Hi all !

I'm sorry but didn't find help on the archives.

My question is simple :

How could I force one Layer (MyEsriLayer extends EsriLayer) to
be the most important to redraw when a projection changed occurs ?

I would like it to redraw fast cause other layers are very
slow WMSPlugIn and I can't wait for all the layers to be
loaded. It seems they slow down my MyEsriLayer's loading.

Thanks in advance and a happy new year to all of you !

Hi,

One other question. In my toolbar I put a zoomPanel. Sometime
this one becomes not editable, I can select the text in it by
double clicking but writing is impossible, the cursor is not
here. 
It comes to a normal behavior after some operations (resizing
the windows, clicking on the map...) I can't determine what
really happens. Any idea ?

Thanks in advance.

Thanks for the answer!

Currently, it is two projections, google for the base map and EPSG: 
4326 for the overlay. I was just thinking of implementing the google  
projection in my wms-service to prevent openlayers from stretching  
the image and thereby reducing the number of projections to one.

It is not that important, I am very pleased by the current  
functionality. Thanks a lot for openlayers!

  - Tore.

Hi...

I was wondering if there was a reason the QuadTree bounds is unavailable ??

It seams it would be convinient to get the bounds like:

        // 
------------------------------------------------------------------------------
   /**
     * Get the bounding box of the object
     * @return QuadTreeRect Bounds of QuadTree
     */
    public QuadTreeRect getBounds()
    {
            QuadTreeRect retVal = null;
            if(top != null)
            {    retVal = top.bounds;
                retVal = new QuadTreeRect(retVal.north, retVal.west, 
retVal.south, retVal.east);
            }       
            else
            {    retVal = new QuadTreeRect(0f,0f,0f,0f);}
            return retVal;
        } // QuadTreeRect getBounds()

Hi all !

I'm currently trying to program a synchronised polygon edition
with a View of my program ! I wrote a MyEditableOMPoly witch
canGrabGraphic value is false.

When I select an OMPoly, the grabPoints appear and all goes
well. The graphic is not entirely moveable.

But I found that when no graphics are selected and I'm in a
mousemode my layer responds to, if I press the mouse on a poly
then drag, the poly moves. Then it's selected and I can grab
the entire poly. 

If deselect then reselect, the behavior returns to normal !

Any idea ?

thanx

Hello Don and Tore!

Is it possible now to use OpenMap as WMS server for OpenLayers?
Having quick look around openmap CVS I did not find corresponding code.
Ping :) 
(http://openmap.bbn.com/mailArchives/openmap-users/2006-12/5100.html)

Sincerely,
  Ru.

Hello.

I do not think the code has been included in cvs yet. I have done  
some more improvements in my local copy that I will try to make a new  
patch from.

  * projection codes was duplicated in both java code and properties- 
file. fixed.
  * fixed transparent png images.

It still does not work with all WMS-clients. I am using OpenLayers to  
overlay WMS-layers from OpenMap over Google Maps. Pretty cool.

  - Tore.

Hello.

Here is a new version of the WMS server patch. It is still not  
complete, but works well with OpenLayers and uDig. Please let me know  
of anything that must be changed for this patch to be accepted.

Changes since the prev version:
* Projections defined in openmap.properties are used in  
checkProjectionType as well. projections were hardcoded here.
* Case insensitive wms request parameter names. Needed by TileCache.
* Transparent images.

In addition, I have the following in openmap.properties. EPSG:4326 is  
safe, but I am not completly sure that I have found the correct code  
from Mercator.
###
# wms config
# separate aliases with space

Hi..
 I'm trying to use Icon Images with locations.
When I use Images loded from the disk it works fine.
When I  use the same image from BufferedImage it doesn't draw.
I've traced it to 'OMRasterObject.render.java' (line357)

//--------------------------------------------------------------------------------------
            if (g instanceof Graphics2D && bitmap instanceof 
RenderedImage) {
                // Affine translation for placement...
                ((Graphics2D) g).drawRenderedImage((BufferedImage) bitmap,
                        new AffineTransform(1f, 0f, 0f, 1f, point1.x, 
point1.y));
                // Undo the affine translation for future graphics??
                ((Graphics2D) g).translate(-point1.x, -point1.y);
            } else {
                g.drawImage(bitmap, point1.x, point1.y, this);
            }
//--------------------------------------------------------------------------------------
When I load the Image from disk it's a 'sun.awt.image.ToolitImage' and 
it renders just fine.
When It's loaded from memory(image I've drawn)  it's a 
'BufferedImage'/RenderedImage' it does not render.

Any Ideas ??
Any insight on this would be appriciated.
    Thanks
       JR

It works when I use:
Toolkit.getDefaultToolkit().createImage(BufferedImage.getSource());

Hi...

 I'm looking to see if there is anyone that is intrested in 
subcontracting some work on Openmap.

We need some changes made to the Shape layer.
These changes are designed to make  interaction with Polylines/Roads better.
Specificly:

1) Better control of labeling.
    a) Ability to specify  label Column(s) in properyfile/GUI.
    b) Ability to specify more granular min/max zoomfactor based on 
attribute values.
    c) Decluttering of labels.
    d) Rotating labels to follow Polyline/Road.

2) Improve performance with large dataset.
    a) Change the shape layer to NOT project and draw all the objects 
that are offscreen.

There are other thinkgs to solve as well, but we can work out details at 
some later stage.
  If anyone is intrested, let me know. Also, please give me an 
indication of rates/costs.
   Thanks
       JR

Hi all -
=20
We are using an AreaShapeLayer to display provinces in Iraq. We =
generated a shapefile using ArcView and, using the generated .dbf file, =
we can get mouseover information about the name of the province, etc by =
setting up the appropriate properties to drive the AreaShapeLayer.
=20
Now, we are trying to do some computation about those areas. =
Specifically, we want to be able to create a new region based on the =
aggregation of several provinces. Using the United States as an example, =
we'd like to be able to outline New England by combining the shapes of =
Maine, New Hampshire, Vermont, Massachusetts and Connecticut. Once we =
have a combined shape, we want to draw that as an outlined polygon.
=20
We are trying to access the OMGeometryList objects that are part of the =
PoliticalArea objects but the lists are empty when we try to do that. =
Perhaps we are trying to access them too early in the pipeline? What we =
have tried to do is extend the AreaShapeLayer class and override =
something like paint() and access the PoliticalArea objects using =
findPoliticalArea of the AreaHandler class.
=20
Is there an easier way to do this (or rather a way that works)? :)
=20
Thanks
Chris

Hello All,

Please let me know if this sounds crazy.  I'd like to create a layer
that brings image tiles into view as I zoom in (like google Maps or
Google Earth).  The current basic earth layer (Political Boundaries) is
slow when zooming and panning.  I'm thinking a collection of
ortho-rectified png tiles that can be addressed by x,y, and z would
provide pretty fast zooming and panning.

Anybody have any experience with this kind of thing?

Thanks
-Tom

Hi Thomas,

This doesn't sound crazy, but I think openMap wasn't designed to manage 
this kind of display system.
The idea of openMap is to draw a layer completely when its content is 
ready. Avoiding this principle means avoiding openMap imho...

Take a look at JXMapViewer and its TileFactory. There is already a WMS 
tile factory and it also works directly with Googles map thing (I think 
there are legal issues with this however). Combining it with the raster 
reprojection/scaling facilities off GDAL should make it possible to make 
an OM layer without doing to much work.

More on on JXMapViewer here

Hi Chris,

You're probably trying to get the geometries before they are loaded.   
You can call getAreas().getGraphics() on the layer to get the  
AreaHandler to load the geometries.  That's usually done when the  
layer is added to the map for the first time.

Thanks Don. I now get back an array of OMGraphicList objects, one list
for each defined area. Now, I have two questions:

1. How do I relate a particular OMGraphicList with one of the
PoliticalArea objects that I can access via id (e.g. "IRQ-AAN")?

2. Once I'm able to determine the mapping from id to OMGraphicList,
what's the best way to combine the shapes together to form a new shape
and then only draw the outline of that new shape?

Thanks,
Chris

p.s. Yes, this is the same issue that Karen Harper emailed the openmap
list about. Didn't realize she had done that. :)

You should be able to call:

OMGraphic.getAttribute(ShapeConstants.SHAPE_INDEX_ATTRIBUTE);

which will return an Integer that is the index for that shape.  This  
number will correspond to the row number of attributes in the  
DbfTableModel.

There really isn't anything in OpenMap that will do this, but you  
should be able to retrieve the coordinates of the shapes from the  
OMGraphics.  For OMPolys, calling getLatLonArray() will return the  
lat/lon in *radians*.  You can covert them to decimal degrees if you  
like, but you probably want to make a copy of the array first.  With  
the coordinates, you have some options.  You might want to check the  
JTS part of the JUMP project (http://www.jump-project.org/project.php? 
PID=JTS&SID=OVER) to do geometry operations.  You could also iterate  
over the coordinates looking for common points in the opposite  
direction, and create a new coordinate array based on those findings,  
copying the unique coordinates into the new array.

Hope this helps,

- Don

Looks pretty close, but no altitude (z) is required in the data for
CSVTiledImagePlugIn.  That would put the icing on the cake.  We'd need
at least 3 images to accommodate min zoom to max zoom, without too much
pixilation.

Thanks for the pointer.

Hello All,

Please let me know if this sounds crazy.  I'd like to create a layer
that brings image tiles into view as I zoom in (like google Maps or
Google Earth).  The current basic earth layer (Political Boundaries) is
slow when zooming and panning.  I'm thinking a collection of
ortho-rectified png tiles that can be addressed by x,y, and z would
provide pretty fast zooming and panning.

Anybody have any experience with this kind of thing?

Thanks

Thanks a lot Don! In case anyone was curious, this is the code I wrote
that performs the aggregation of areas. I wrote it using the
java.awt.geom package classes and, for now, have stuck it into my own
extension of the BasicMapPanel. I also realized that the OMPoly object's
have the Integer index set as their appObject and you can look up the
name of the OMPoly based on that Integer so that worked out well. In any
case, it's working the way we expect now.

Hello.

Here you have an updated version of the WMS patch. It revert a change  
from Vector to List in ProjectionFactory as at least  
com.bbn.openmap.gui.menu.ProjectionMenu need it to be a Vector.  
Thanks Ru for pointing out the problem.

Changes to existing files that are in CVS:
http://www.pvv.ntnu.no/~halset/tmp/20070124-openmap-wmsserver- 
changes.patch
Files that are not in CVS:
http://www.pvv.ntnu.no/~halset/tmp/20070124-openmap-wmsserver-new- 
files.zip

I have also tested this with ossimPlanet and it works well. Very cool!

Hi,
I've implemented a chart-plugin to ms-iis. This module is listening to
requests from users, and sends a png back to the user based on these
parameters;
LatLon-center, scale, image width and image height. The chart api is based
on Mercator-projection.

I have tried to implement this in openmap as a nearly-wms-service. I've made
a plugin like this;


public class CMAPPlugIn extends WebImagePlugIn implements
ImageServerConstants{

    /** Creates a new instance of CMAPPlugIn */
    public CMAPPlugIn() {

    }

    public String createQueryString(Projection p) {

        LatLonPoint center = p.getCenter();
        float center_lat = center.getLatitude();
        float center_lon = center.getLongitude();

        float scale = p.getScale();
        int height = p.getHeight();
        int width = p.getWidth();


        String url = "
http://www.myserver.com/init.dll?Render?CENTER_LAT="+center_lat+"&CENTER_LON="+center_lon+"&SCALE="+scale+"&IMG_WIDTH="+width+"&IMG_HEIGHT="+height+"&IMG_FORMAT=1
";
        return url;
    }

    public String getServerName() {
        return "name";
    }

}



this I add to a pluginlayer.

My problem is that it works almost fine, but there seems to be som problem
with the scale factor. Can anyone please help me with this?

Thanx, I've tried that, but it didn't work. The problem is that the
chartserver uses Transverse Mercator instead of Mercator. Anyone implemented
this projection?

Hi Tore,

I've incorporated these updates into the code base.  Sorry for the  
delay in getting this done, and thanks for your persistence and updates!

Hi again,
The projection of my chart-api is indeed Mercator, not TMercator as I
thought. The center point of the map seems to be right, but when you place
icons around the map, it seems to be dislocated when you reach the corners.
When you zoom out it gets worse. Any ideas?

Hi Erling,

I does sound like the scale factor is doesn't match, which isn't that  
surprising because scale is kind of an arbitrary factor.  Is it  
possible to ask the server for an area based on a bounding box?  If  
you can get more information about the corner coordinates of the area  
returned from the server, you can use the ProjMath class to figure  
out what the 'openmap' scale of the image is, and either come up with  
a multiplier to use for future requests or use a OMScalingRaster to  
display the image based on the corner points.

Hope this helps,

Don

Hi Chris,

Thanks for the update and for showing the code that worked out for you.

I'm moving away from using the AppObject in OMGraphics directly, and  
I'm using the putAttribute()/getAttribute() methods instead, so you  
might expect the OMPoly's appObject to be a hashtable in future  
releases.  If the index attribute isn't available from the  
getAttribute(SHAPE_INDEX_ATTRIBUTE) on the OMPolys, it will be for  
the next release.

Regards,

Don

Hi JR,

You should be able to use a BufferedImage directly.  I do this all  
the time, creating a new BufferedImage with a certain image type,  
getting the Graphics object from it an rendering into the image, and  
then sticking it in a OMRaster.

Hi...
 I've created a Spatial Index package/class that does helps out a lot 
on  a ShapePlugin layer.
It's loosly based on the Shape.SpatialIndex, with minor changes.
It's only a lineas search right now, but it makes it concidderably 
qucker to redraw the screen.
I'll share it to be included if there is an intrest.

   JR

P.S. I also tried it with an R* tree, but the improvements were 
marginal, and creation time was exponential.

You can figure out the points you want the text to align itself with,  
and then find the azimuth between them using the  
com.bbn.openmap.proj.GreatCircle class method.

No, none in the OpenMap package itself.

I can see how you would use this in an OMLabeler, but it also seems  
like something a specific labeler implementation would use  
internally.  I think you could put these methods in any  
implementation of OMLabeler, or subclass of OMTextLabeler, without  
having to add them to the OMLabeler interface itself.

Don

Hi, William,

Thank you for your response.  I found a way although not a desired one.
I chain these layers from top to bottom, with each layer knows the next
layer below.  I override "findClosestLocation" as following.  In this
way, an upper layer will get the priority.

LocationLayer nextLayer;
public Location findClosestLocation(MouseEvent e) {
  if ( ! isVisible()) {
    if (nextLayer == null)
      return null;
    else
      return nextLayer.findClosestLocation(e);
  }
  Location loc = super.findClosestLocation(e);
  if (loc == null) {
    if (nextLayer != null && nextLayer.isVisible())
      loc = nextLayer.findClosestLocation(e);
  }
  return loc;
}

-Sunny Lin

Hi Sunny,

don't know if anyone has responded to this yet.

It sounds as if your top-most layer is consuming the mouse events.
You need to tell either the mouse mode or the mouse listener methods not
to 
consume events. There is more than one way to do this I think, depending
on your 
event needs. Look at the mouse*() methods in MapMouseListener, and at 
setConsumeEvents() in AbstractMouseMode.

Hi Sunny,

don't know if anyone has responded to this yet.

It sounds as if your top-most layer is consuming the mouse events.
You need to tell either the mouse mode or the mouse listener methods not to 
consume events. There is more than one way to do this I think, depending on your 
event needs. Look at the mouse*() methods in MapMouseListener, and at 
setConsumeEvents() in AbstractMouseMode.

Hope this helps, Bill

Hello.

I am doing some profiling of my app here and it looks like Debug is  
using way too much cpu. Ofthen used methods like Length.roRadians and  
LLXY.forward all calls Debug.debugging that does a  
Hashtable.containsKey.

I do not want and openmap debug output, but changing Debug.On to  
false is not possible as it is static final.

Here you see a screenshot from jprofiler. This is the CPU Hotspot  
view. Projection and drawing are taking most of the cpu, but I think  
Debug is taking way too much.
http://www.pvv.ntnu.no/~halset/tmp/20070207-openmap-jprofiler.png

Is there a master plan for logging in openmap? Like switching to a  
more common logging solution. Or should I hack my own Debug to set  
Debug.On to false?

  - Tore.

Hi Tore,

Thanks for the profiling information.  It looks like those three  
com.bbn.openmap.proj methods are the main hotspots for Debug, so I  
can take a look at that to reduce the load on Debug for the next  
release.

The master plan for OpenMap logging is to move to the logging  
mechanism in the jdk.  For all of the new code I've written for  
OpenMap I've replaced Debug with Logger, and I'll be re-factoring the  
other classes for the 4.7 release.

I'm not sure why the Debug.On flag is final, it shouldn't be.

- Don

Hi,

What about Log4J instead of the jdk logging ?

Hi Geir,

I've used both, and also considered using the Commons Logging API,  
and decided to go with what's in the jdk in order to minimize  
OpenMap's dependencies on third party APIs.  I couldn't find a  
significant advantage for using log4j that offset the requirements of  
adding yet another jar to the classpath.

Regards,

Don

Hi...
 I read that you're planning a new release here sometime(soon I hope :).
Is there a process for getting changes put into the next release.

I have a couple of chanegs that I'd like rolled in.
I've mentioned these before, though I've not gotten any response.
I understand we're all busy and don't have time to chatter, but there 
are some
changes that would be beneficial to those of us who rather not change 
the base source.
(I'm not critisizing, just trying to contribute)

1) In-Mem spatial Index, I posted the to some people already.
2) Object labler/formatter class. ( I have one for Shape labler )
3) Tracing Labels for polylines(only on shape files) that hides lables 
that are labeling object too mall)
      Here I could use access the calculated text/font metrics etc.
4) Filter on the Shape dbf stream to eliminate the columns we're not 
intrested in.
     (Would be very handy, some of the shape files I have are in the 
1/2-1 Gig range(200MB shape, 800MB dbf).
 
Anyways, there are some others to, but those are the ones off the top of 
my head.
I'll contribute the things I've done any way you want, just let me know 
how....
   Thanks
      JR

Sure, you would just sent them in to openmap-users@bbn.com or  
openmap@bbn.com.

That's OK, we appreciate the contributes and criticisms.  Sometimes a  
feature isn't in a component because we wrote something we needed,  
and we didn't need a particular feature that is entirely obvious for  
a different use case.

I am interested in seeing what the difference is between yours and  
the one in the toolkit.

Sure, sounds interesting.

I think you can get that stuff from an OMText, no?  Interesting idea  
for the tracing label, how does it affect performance (memory usage  
and generation)?

This one is interesting and needed, too.

They all sound like good improvements, please go ahead and mail in  
what you'd like to contribute.

Regards,

Don

Hi...

I do understand that, that is the way we work to.

Well...
The only one in the toolkit i saw was 
com.bbn.openmap.layer.shape.SpatialIndex.
This one is based of that one, but it will index an arbitrary 
OMGraphicsList..
The reasong I created it was that I was using EsriPligin.
It ignores the shx, (which is reasonable if you're loading over the net) 
so it painted everything, even the offscreen stuff.
Given the size of our datasets, that made it unusable.
The Spatial Index is just a linear search(not even ordered), but it does 
wonders for the redraw...
It's pretty quick to "index" and performs OK on search
I tried the same approach with an R* tree implementation, but the 
creation time was horrendus.

> 2) Object labler/formatter class. ( I have one for Shape labler )
> Sure, sounds interesting.

OK... We've been using this approach for years with our DB GUI
UnitHandler is a LocationLayer
UnitHandler.colorFormat=Inactive:lightgray/Active:green:black/ALERT:red/STOPPED:yellow/OFFLINE:darkgray/STALE:Gray/PURSUIT:red(1):red

It would be available but not until after the setLocation() call.
I could not figure out the correct sequence of events, so I just used a 
static for the min size.
The performance is fine (when I don't have to draw all the off-screen 
objects).

Just give me free reins and the latest copy of the files and I'll do it.

Hello,
I try to display a LambertConformal raster map on OpenMap but I am not able to
change the meridian used to display the world layer. I tried to change the
getUpperLeft and getLowerRight code to this :
        return new LatLonPoint(90.0, -180.0 + centralMeridian);
and     return new LatLonPoint(-90.0, 180.0 + centralMeridian);
respectively.
I expected the world map to rotate in order to have my centralMeridian in a
vertical way but the world layer stays with the meridian 0° vertical.

Do you have any clue to change this ?

Regards,
Fred

Hi,

I am using the Drawing Tool Layer and the corresponding Drawing Tool =
Launcher widget for initiating drawing.

When opening the Drawing Tool Launcher widget and pushing the Create =
Graphic button I get a "Problem" popup windows displaying the text :

Problem creating new graphics:
No valid receiver for the created graphic.

The Send To Selection pull down list shows one item :

	Drawing Tool Layer

I thought this was the receiver. Am I wrong ?

The problem is not happening always but I have not been able to figure =
out why and when I get the "Problem" popup window

Got a clue anyone ?

Camille,

Thanks for the feedback.
I have investigated a bit further and found :

What you state seems to be correct if there are > 1 item in the combo box.
But not with only one item.

When I started debugging the code of OpenMap (4.6.3) class OMDrawingToolLauncher
I found that the ActionListener method tied to the JComboBox will not be called when there is only one item in the JComboBox.
I will do a private quick fix in the OpenMap source (I am in a hurry) but to me it seems this must be a bug and should have a proper fix.

I am running Java 1.6, having recently switched from 1.5 and have a suspicion that the behaviour was different under 1.5.    

Anyone else with an opinion here ?

/Geir

Hi !

I also noticed that behavior and realized that even if the combo box displays the layer you want to draw on, you must "reselect" it in the combo, I mean, display the list and click on Drawing Tool Layer, then it works !

Hi Fr=E9d=E9ric,

Enclosed you will find my update of the openmap projection. I also found=
 some strange things and thus changed the projection to my needs. it has=
 been used for belgium. maybe it is useful for you.

Subject: [OpenMap Users] Rotation of map in Lambert projection

Hello,
I try to display a LambertConformal raster map on OpenMap but I am not a=
ble to
change the meridian used to display the world layer. I tried to change t=
he
getUpperLeft and getLowerRight code to this :
        return new LatLonPoint(90.0, -180.0 + centralMeridian);
and     return new LatLonPoint(-90.0, 180.0 + centralMeridian);
respectively.
I expected the world map to rotate in order to have my centralMeridian i=
n a
vertical way but the world layer stays with the meridian 0=B0 vertical.

Do you have any clue to change this =3F

Regards,
Fred

Speaking of the Lambert projection, shouldn't one be able to use this 
projection to convert from State-plane coordinates to Lat/Lon and 
vice-versa?

I tried it using this approach:

            LatLonPoint center = new LatLonPoint(30.1167,-100.3333);
            LambertConformal lambert = new 
LambertConformal(center,1000000.0f, 500,500,
                                        -100.3333333333333, 
30.11666666666667, 31.88333333333333,
                                        29.66666666666667,700000,3000000);
            Point2D pt = new Point2D.Double();
            lambert.LLToWorld(30.015643,-98.179725, pt);
            System.out.println(pt.toString());
and get this:
            Point2D.Double[0.039672363330592424, 1.6755878139863907]

I should be getting numbers for easting and northing in the hundreds of 
thousands to millions.

Does anybody know how to transform these numbers into Easting and 
Northing in meters or feet?

(I need to be able to convert back and forth in order to display some 
imagery data from a server that expects the bounding box to be specified 
in the state-plane coordinate system.)

Thanks

Rob

Thank you but I already patched the LCC openmap projection with code from java
map projection library (http://www.jhlabs.com/java/maps/proj/ ). It does not
work very well in southern hemisphere at this time and I did not find why. If
someone is interested in testing it, I can post the patch here.

It looks like Chris's version of the LambertConformal works much better!=20
Thanks Chris!
(I'm testing it out now on the imagery data server.)

           Point2D.Double[0.039672363330592424, 1.6755878139863907]

I should be getting numbers for easting and northing in the hundreds of=20
thousands to millions.

Does anybody know how to transform these numbers into Easting and=20
Northing in meters or feet?

(I need to be able to convert back and forth in order to display some=20
imagery data from a server that expects the bounding box to be specified=20
in the state-plane coordinate system.)

Thanks

Rob

It looks like Chris's version of the LambertConformal works much
better! Thanks Chris!<br>
(I'm testing it out now on the imagery data server.)<br>

Speaking of the Lambert projection, shouldn't one be able to use this
projection to convert from State-plane coordinates to Lat/Lon and
vice-versa?
<br>
<br>
<br>
I tried it using this approach:
<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LatLonPoint center = new LatLonPoint(30.1167,-100.3333);
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LambertConformal lambert = new
LambertConformal(center,1000000.0f, 500,500,
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -100.3333333333333,
30.11666666666667, 31.88333333333333,
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
29.66666666666667,700000,3000000);
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Point2D pt = new Point2D.Double();
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; lambert.LLToWorld(30.015643,-98.179725, pt);
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; System.out.println(pt.toString());
<br>
and get this:
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Point2D.Double[0.039672363330592424, 1.6755878139863907]

Chris,

Would you mind defining a, ba and e?

I assume that "a" is equal to the first term  (6378137)of  the Spheroid 
number below.

My northing values are off by a factor of ten so I think I need to tweak 
these parameters for my SP coordinate system.

Thanks,

Rob

Hello Rob,
It has been a while since I produced that code, so I would like to refer you
to a manual where you can find those definitions:
http://remotesensing.org/geotiff/proj_list/guid7.html
1.4.1.4 Lambert Conic Conformal (2 SP Belgium) (EPSG coordinate operation
method code 9803)
Hope this helps

Hi Geir,

I can't reproduce this behavior in the beta, so it might have been  
something that has been fixed.

You can get the beta from the download page on the website if you  
want to test it in your environment.

Hi !

There is a shapeFile bundled with openMap (dcwpo-browse.shp) which contains 
political boundaries.
Unfortunately, this dataset is not up to date.
I'm searching for an up to date (and free) one... Multiple resolutions 
would be better, but I can't ask too much !
Can someone provide me (a link to) such data ?
Thanks a lot in advance !!!

Stephane

Hi Stephane,

I only use dcwpo-browse shp file for the overview map, because it it  
pretty lightweight.  The cntry02 shp file in the package is from  
2002, and is more accurate (and larger).

Hello,

I'm working on a crime simulation project that uses the simulation
framework Repast. This framework has openmap integration which I want to
exploit to plot known crime incidents by a sort of density surface or
hotspot layer. On the homepage of OpenMap there is this image:
http://openmap.bbn.com/images/etopo.png. This image seems to show some
of this functionality. However, I am not able to find the right
information on these functions. Can someone give me some hints here?
When I used google I was overwhelmed by all kinds of irrelevant
information.

So in short my question is:

Is there some kind of density surface layer or hotspot layer
functionality? If yes, where can I find an example, tutorial, etc?

Thanks in advance,

Jeroen

Hello,
I'm trying to implement the Transverse mercator projection to display raster
maps projected using this projection. Is it possible ? Do I only have to create
the projection in the com.bbn.openmap.proj package ? Are there mandatory methods
to implement to display data along the abstract ones ?

Thanks for your answers.

Fred
PS: I still have problem with my LCC projected raster map on the LCC projected
vector openmap map.

Hi Jeroen,

You can create a density surface several different ways in OpenMap,  
but it comes down to having your layer display the information in an  
OMRaster (OMRaster, OMScalingRaster) object, or an OMGrid object.  It  
depends on what your source data looks like and how you access that  
data.  To use an OMRaster, you would create a  
java.awt.image.BufferedImage and render directly into it based on  
your data, and then pass that BufferedImage to an OMRaster for  
positioning.  That would force you to manage the representation of  
the data in the image.

The OMGrid is really build for representing grid data, though.  You  
use a GridData object to hold your data values, and the OMGrid object  
holds the GridData and the position information about the GridData.   
The OMGrid also uses an OMGridGenerator object to interpret the  
GridData and create other OMGraphics to render to the map.  The  
OMGridGenerator is really where your focus will be, because that's  
what decides how your data will be visualized.  The  
com.bbn.openmap.omGraphics.grid package contains a bunch of  
OMGridGenerator implementations, the simplest one being a  
SimpleColorGenerator that interprets the grid data as color values.

I'd start with a Layer that extends OMGraphicHandlerLayer and  
overrides the prepare() method to return an OMGraphicList with an  
OMGrid on it.  Use the prepare method from the DemoLayer as an  
example of mananging the OMGraphicList for a layer, and how to create  
an OMGraphic once and reuse it of for different projection changes.

Then, get your data into an OMGrid object, create/use an  
OMGridGenerator that creates a visualization to your liking.

Hope this helps,

Don

Hi all,
 
A short question for help :
 
How do one check if a LatLonPoint is contained within an OMPoly/OMCircle/OMRect ?
All coordinates I handle are in Lat,Lon degree format.

Hi Stephane,

Thanks for the code, this is a cool addition.  I'll incorporate it  
into the code base.

Hello.

I am working on a project to use OpenMap as a WMS server. It is  
working very well, but it does currently only support SRS=EPSG:4326  
(unprojected). I want to support OSGEO:41001[1] (Mercator) as well.

The problem with OSGEO:41001and a lot of other SRSs used in the OGC  
WMS/WFS world is that the units are in meters instead of in degrees  
lat/lon. To match OpenMap projection system (based on lat/lon) I  
guess I will need a frontend that convert all incoming meters to  
degrees before handling over to OpenMap projection.

I know of Length.METER and have used it to find distances, but I do  
not know how to use it or anything else to convert incoming x/y in  
meters to lat/lon. Perhaps I can use Length.METER to convert the  
direct distance between the projection origin and the point and then  
the same for delta lat. Using it for delta lon will not work (as the  
world is not flat), but Pythagoras should help me find this last number.

Am I thinking correct here? Anyone done this before in OpenMap and  
want to give me some hints?

Regards,
  - Tore.

Hello.

All my OMGraphics have appObject to point back to the underlying  
feature object. In a Layer I can then do a prepare().findAll(...) if  
a user wants information about some features.

This works pretty well in most situations, but not so elegant for  
features that need a OMGraphicList to represent the view. The problem  
is that OMGraphicList.setAppObject does not make sure all the  
graphics in the list have the same appObject, so findAll() may return  
OMGraphics without a appObject.

To overcome this problem I have created my own subclass of  
OMGraphicList that overrides setAppObject to set appObject on all  
subgraphics as well and _add to set the appObject on OMGraphics added  
at a later point in time. See attached code.

Do you think this should be the default behaviour of OMGraphicList?  
Any reason to why this may *not* be a good

(On a side note: I sure hope it (in the future) will be possible to  
still have the appObject as a single Object ref and not a Map as I  
operate with a huge number of OMGraphics and do not want all those  
extra Map-objects.)

Regards,
  - Tore.

     public synchronized void setAppObject(Object obj) {
         super.setAppObject(obj);

         for (Iterator it = iterator(); it.hasNext();) {
             OMGraphic g = (OMGraphic) it.next();
             if (g.getAppObject() == null) {
                 g.setAppObject(obj);
             }
         }
     }

     protected synchronized void _add(OMGeometry g) {
         Object appObject = getAppObject();
         if (g.getAppObject() == null) {
             g.setAppObject(appObject);
         }

         super._add(g);
     }

Dear all,

My name is Rui Lopes and I am new to openmap. I am a student of Informatics
Engineering in Coimbra, Portugal.
I have a model built in RepastJ, that needs 512 MB o memory to run.  I've
been using the repast gui tools to display the world. Now I wan't to
integrate it with a GIS software, in order to, hopefully, have better
performance on the visualization and extra GIS functionalities. 
I started by trying OpenMap. RepastJ offers inbuilt functions to use
openmap, but they are quite limited. One has to load agents from a shape
file for example and use a library to create the GIS agents. So, I
integrated it directly with openmap by creating my own
OMGraphicHandlerLayer, following the samples in the openmap package. This
worked, but now I need to the double the memory in order to run the model
and I am not able to deal with the gui, because my computer is almost
freezed (I have only 1024MB ram).
The thing is that the world is a grid of 2400x1200, what gives at start
2880000 objects (I used OMRect), that change, at least some do, every tick.
Is this a plausible number of objects to use in openmap or should I forget
it?
Has someone used some GIS software with such a large number of objects in a
dynamic model? which application did you used? what are the requirements for
a machine to properly deal with a model of this size?

Thanks in advance,
Rui

Hi...
 I tried using it with a 1.5Gb Shape file.
It didn't work too good. I'm sure there is a way to trim it.

Hello there,
I'm very impressed with the capabilities of OpenMap, thanks to all involved.

However, have a problem I've been trying for a few hours to fix to no
avail.



I've been trying to get an applet to load a shapefile defined in the
openmap.properties file as an EsriPluginLayer.



I copied the demo applet and openmap.properties file and defined in the
properties file a shapefile for the applet to load from the server.

This works as the esriPluginLayer when the applet is run locally but not
when it is run on the server. It does work as a ShapeLayer when run from the
server.



This is the error when trying to load the EsriPluginLayer on the server.

*** ERROR ***

PropUtils: AccessControlException trying to access data/shape/cfp.shp

*************

Despite the shapefile not displaying, 'show data table' will display the dbf
file fine.



Text added to the properties file :

        cfp.class = com.bbn.openmap.plugin.esri.EsriPlugIn

        cfp.prettyName = CFP

        cfp.shp=data/shape/cfp.shp

        cfp.dbf=data/shape/cfp.dbf

        cfp.shx=data/shape/cfp.shx



#test loading as shapeLayer rather than esriPluginLayer

cfp2.class=com.bbn.openmap.layer.shape.ShapeLayer

cfp2.prettyName=CFP2

cfp2.shapeFile=data/shape/cfp.shp

cfp2.spatialIndex=data/shape/cfp.ssx



Any suggestions appreciated,

Thanks,

Andy

Don,

Sorry for my late respond, I just recently got again time to work on the
OpenMap aspect of my project. I have experimented a bit with OMGrid and
the OMGridGenerator object. I have succeeded to display a grid with
different colors for different values. However, I'm left with the
following issues:

I use a 100 by 100 grid based on int values. When I zoom far enough,
this depends on the scale and the scale of the OMGrid, I get heap space
problems (load gets easily 1GB+ of memory). Is there a more efficient
class/or method to do this?

I hoped the other Generators would be more efficient, but when I try to
display my Grid with the ElevationBandGenerator or the SlopeGenerator
nothing shows up. What do I do wrong? (the code for
ElevationBandGenerator is commented out in the init method below)


Regards,

Jeroen

Hi Jeroen,

You can create a density surface several different ways in OpenMap,  
but it comes down to having your layer display the information in an  
OMRaster (OMRaster, OMScalingRaster) object, or an OMGrid object.  It  
depends on what your source data looks like and how you access that  
data.  To use an OMRaster, you would create a  
java.awt.image.BufferedImage and render directly into it based on  
your data, and then pass that BufferedImage to an OMRaster for  
positioning.  That would force you to manage the representation of  
the data in the image.

The OMGrid is really build for representing grid data, though.  You  
use a GridData object to hold your data values, and the OMGrid object  
holds the GridData and the position information about the GridData.   
The OMGrid also uses an OMGridGenerator object to interpret the  
GridData and create other OMGraphics to render to the map.  The  
OMGridGenerator is really where your focus will be, because that's  
what decides how your data will be visualized.  The  
com.bbn.openmap.omGraphics.grid package contains a bunch of  
OMGridGenerator implementations, the simplest one being a  
SimpleColorGenerator that interprets the grid data as color values.

I'd start with a Layer that extends OMGraphicHandlerLayer and  
overrides the prepare() method to return an OMGraphicList with an  
OMGrid on it.  Use the prepare method from the DemoLayer as an  
example of mananging the OMGraphicList for a layer, and how to create  
an OMGraphic once and reuse it of for different projection changes.

Then, get your data into an OMGrid object, create/use an  
OMGridGenerator that creates a visualization to your liking.

Hope this helps,

Don

Hello All,

I'd like to drag a circle or rectangle on the map, but I don't want it
to be drawn on the map, or become part of a layer as a shape.  It should
just exist as a dashed line, for example, for the user's visual
pleasure.  If the user clicks away, the dashed line would disappear.
The DrawingLayer seems to do what I need -and more.

Looking for some advise on how to approach this problem.  I'll start by
looking at the Drawing layer and go from there.  Any advise or success
stories anybody can share?

Thanks.
-Tom

Hi all,
=20
Just wondering if there is a way around the 180 degree longitudinal
limit when drawing lat/lon polys and lines ? My app allows the user to
draw an 'Area of interest' (OMRect) and the 180 'flip' is causing some
operator annoyance so I've been asked to look into it.

Jon.

Hi all,

I experienced some problem using the "Save/Load Properties" feature (from
the File menu).
When loading the file (created before by "Save Properties"), some layers
are missing, other arent displayed, and I get lots of exceptions...

Did someone tried to use that feature and succeed loading properties from a
saved file?

regards,

Thomas

Hello, I created a new OMGraphic with his respective Loader and=20
EditableOMGraphic.

For my case, I created a OMFreeHand. It  inherited from OMPoly, and my=20
EditableOMGraphic inherited from EditableOMPoly.

My problem is when Iike edit the OMFreeHand for code. Internally the=20
OMDrawingTool assign the EditableOMPoly for the work, because my=20
OMFreeHand is assignable to OMPoly (inherited from it).
For me the problem is in  public EditableOMGraphic=20
getEditableGraphic(OMGraphic g)  method.=20
I think is better find te classname in the hashmap before iterate on it.

Sorry by my english.

Please tell me if is my mistake o how can I make may better work  about=20
this point.


Thanks in advance.

Hi All,
=20
I've have a base ShapeLayer which has been overridden such that a right
click will display my applications menu (as I don't have a menubar).
This layer displays the basic countries shape file and has
getItemsForOMGraphicMenu(...) and getItemsForMapMenu(...) overridden so
I get the popup menu on both land and sea.
=20
I also have a 'higher' layer which displays some OMGraphics. I've
overridden the getItemsForOMGraphicMenu(...) method in this layer to
display a popup menu for the graphic.=20
=20
My problem is that the 2 layers won't work together. Right clicking
displays the lowest (in layer order terms) menu it can find.=20
=20
As a test I removed the getItemsForOMGraphicMenu method from the base
layer and had my graphic layer draw a filled poly which covered both
land and sea. If I right click on the poly over the sea I will get the
base layer's popup menu and right clicking on the poly over land will
display the graphic layer's popup menu.
=20
How do I make my graphics display the correct popup ?
=20
Thanks,
Jon.

Hello,
 
I'm trying to get an understanding of how to most efficiently display
Lat, Lon of the current mouse position as it moves over the map.  Looks
like CoordMouseMode plays an important part.  I'd like to display Lat,
Lon somewhere on the GUI (not necessarily on the "info line".  I admit
not fully understanding the architectural details of the various OM
parts.  I'd appreciate any guidance.
 
Thanks.

Jeroen,
=20
LatLonPoint.distance(LatLonPoint) will give you the distance between two
LatLonPoint objects in radians.  You can convert it to what you like
using com.bbn.openmap.proj.Length.  Here is an example.
=20
LatLonPoint p1, p2;
......
float dist =3D Length.KM.fromRadians(p1.distance(p2));
=20
This will give you the distance in kilometers between p1 and p2.

Hi, <br>
<br>
This depends on what you mean by correctly.
LatLonPoint.distance(LatLonPoint toPoint) will return a float that
represents the distance between the two points in radians. Use Length
to convert to any other unit of measurement. This returned distance is
not entirely correct, as it is based on a spherical model of the Earth.
However, the margin of error should be about 0.5%.<br>
<br>
If you need to compute the distance more accurately than this I think
you'll have to do it outside OpenMap.<br>

If you want to determine the distance based on an ellipsoid, you can  
use the com.bbn.openmap.geo.Geo class, combined with the Length class:

Length.KM.fromRadians(geo1.distance(geo2));

or, you can also do:

geo1.distanceKM(geo2);

Cheers,

Don

Hi Thomas,

There's a couple of things you can do.  The CoordMouseMode asks the  
InformationDelegator to put the coordinates on its info line  
specified for coordinates  
(InformationDelegator.COORDINATE_INFO_LINE), and to the  
InformationDelegator, that's just a JLabel.  If you want the  
coordinates to go somewhere else, you can create a JLabel somewhere  
else in your application, and tell the InformationDelegator you want  
it to use your label instead.

You can also just put the information delegator somewhere else in  
your GUI and have it display the coords.

You can add a MouseMotionListener to the MapBean to get the mouse  
events.  The MapBean has methods on it that will tell you the  
coordinates of the pixel location, and should be the source of the  
MouseEvents you get.

To get to the MapBean and/or the InformationDelegator, you can use  
the MapHandler in the BasicMapPanel, if that's what you are using.

Hope this helps,

Don

Hello,

I just would like to know if there were a way to set relative path (I'm
using Windows) into the openmap.properties file...
For example, I need to set the "etopo.path" property, and instead
"C:/.../.../data/etopo", I would like to set something like "/data/etopo",
but it seems that doesn't work.

Maybe I've done something wrong?

Thanks in advance

Hi Thomas,

The first '/' is confusing things.  If you use "data/etopo" in your  
properties, and have the first part of the absolute path in your  
classpath, it should work.

Hi Jon,

The plots are interpreted as being placed on the sphere, so the limit  
is there because the code is assuming the shortest path between  
points on the sphere is the intended path between points.

You can get shapes to render that break the limit, but you have to  
construct them with smaller pieces so the whole looks like it's  
breaking the rule.   You'd have to put a switch in the drawing tool  
that specified that the line should take the long way between points,  
so appropriate midpoints could be placed to make the projection code  
do what you expect.

Regards,

Don

Hi Andy,

I'm not sure what's causing the AccessControlException for the  
applet, and I don't see anything in the code that would really cause  
this problem that the ShapeLayer wouldn't also be facing.  The  
PropUtils code throwing the error is used by both the EsriPlugIn and  
the ShapeLayer.  I'm kinda stumped.

What version of Java are you running, and what platform?

- Don

Hi all,

I have the following problem: when I want to zoom in on a particular
data set (in this case an OMCircle) by using the menu function View ->
"Go over data. It zooms completely wrong; it zooms out instead of in and
it seems to move away from the data set as well. For the other data
layers it works all right, but I don't understand why for this layer it
does not.

=20

For example I have a layer which contains streets. When I use "Go over
data" it zooms in correctly, but when I use this same function for the
circle layer (which actually lies within the streets layer) I zooms out.
I cannot find the problem, can someone give me a hint?

=20

Regards,

Jeroen

PS Thanks for all the replies on the distance between two points it
worked!

Hi Don,

I'll send you a screen copy of the stack trace as soon as possible.

Anyway, I looked forward, especially into the generated properties file,
and the problem seems to be caused by lots of empty property values (like
for example the CSV.defaultIconURL).



Regards,

Thomas



PS: I'll send the stack trace asap...





Hi Thomas,

Do you have a stack trace I could look at?

Hello.

I am build support for UTM projections into the WMS-part of OpenMap.  
I am using UTMPoint for the calculation, but would like to be able to  
convert a LatLonPoint to a UTMPoint for a specified UTM zone that may  
not include the given LatLonPoint. This is normal practice in the WMS  
context.

Does this seem to be a good idea? I have attached a patch to UTMPoint  
that works for me.

Regards,
  - Tore.

Hello.

I have created a Transeverse Mercator Projection class based on  
UTMPoint. It seem to work pretty well in my application. It is based  
on my changes to UTMPoint:

http://openmap.bbn.com/mailArchives/openmap-users/2007-03/5226.html

Here are the projection and projection factory:

http://www.pvv.ntnu.no/~halset/tmp/20070319-openmap-utmproj.tgz

It is possible to optimize the code by reducing the number of  
LatLonPoint and UTMPoint objects that are created, but that will  
require some more changes to UTMPoint.

I have only used this with WMS (ImageServer), not in the OpenMap GUI.

Regards,
  - Tore.

Hello,

=20

I have an OpenMap display that shows a map with streets. I'm using this
map to show where street robberies take place. What I want now is to
change the color of the street depending on the number crimes that have
committed in that street. For example, a street with a low crime density
would be blue and one with a high crime density would be red. I want to
be able to set this color after I have loaded the shapefile.? I know how
to set the color for all streets with the Properties class, but how can
I do this for each specific street ? Should I set the color as an
attribute and specify colors for certain values?

=20

=20

Thanks and regards,

=20

Jeroen

Hi...
That's esentially what I did for Locations/Points:
Sorry if the comments leave a little to be desired
I use it to create colored Icon's for the Location as Dot's.
You can probably change it to update the "DrawingAttribute.lineColor"
Here is my property string
UnitHandler.colorFormat=3DInactive:lightgray/Active:green:black/ALERT:red=
/STOPPED:yellow/OFFLINE:darkgray/STALE:Gray/PURSUIT:red(1):red

Start in :DBLocationHandler.reloadData(QuadTree qt)
Then:
UnitData.load(RecordSet drs, LocationColorFormatter colfmt) throws=20
SQLException
Hope it helps

/**
 * The DBLocationLayer is a LocationHandler designed to let you put
 * data on the map based on information from a Database. The
 * properties file lets you set defaults on whether to draw the
 * locations and the names by default. For crowded layers, having all
 * the names displayed might cause a cluttering problem. In gesture
 * mode, OpenMap will display the name of each location as the mouse
 * is passed over it. Pressing the left mouse button over a location
 * brings up a popup menu that lets you show/hide the name label, and
 * also to display attributes of the location in a Browser window that
 * OpenMap launches.
 * 
 * <P>
 * If you want to extend the functionality of this LocationHandler,
 * there are a couple of methods to focus your changes: The
 * setProperties() method lets you add properties to set from the
 * properties file. The createData() method, by default, is a one-time
 * method that creates the graphic objects based on the data. By
 * modifying these methods, and creating a different combination
 * graphic other than the default LocationDataRecordSet, you can
 * create different layer effects pretty easily.
 * 
 * <P>

One thing we did was schedule repaints at some user-specified value 
(defaulted to 250 ms). It only repainted if something changed as well. 
The idea was to coalesce paints. (I haven't looked into it much, but I 
imagine that one could create a RepaintManager that did that for the 
entire application so that the application code wouldn't have to change.)

Also, make sure layers like the VPF layer are using the  
BufferedImageRenderPolicy.  Your poly layer might benefit from using  
BufferedImageRenderPolicy as well.

Hope that helps,

Rob

p.s. Let us know  what you finally come up with!

We also doing scheduled repaints. IIRC we deal with 2000 objects 
repainted each second. Of course repaint time might be adjusted by user.
In our applications we have several so called dynamical layers. One 
thread is responsible for preparing data for them (especially 
interpolate new position of moving objects). After that repaint is 
called in EventDispatchThread.

Agree with that :)

Hi Tore,

Thanks for sending this class and the UTM projection in, I'll take a  
look at them this week.

Best Regards,

Don
