Re: [OpenMap Users] OMArc uses LatLonPoint

Don,

We are reusing a layer from another map that uses LLXY projection. That layer used OMCircle. When we created this new map tool based on the Cartesian projection points where not drawn past -180 to 180 and -90 to 90. That's why we switched it to OMPoint.

So far the Cartesian projection is working. On thing we noticed was the NavMouseMode would not zoom in. The method Cartesian.getScale(Point2D ulWorldPoint, Point2D lrWorldPoint, Point2D point1, Point2D point2) was not returning the correct scale, but we worked around that. The second two parameters needed to be 0,0 and projection.getWidth(), projection.getHeigth().

Hi Kevin,

I can do that, but what's the difference between that and using an
Arc2D object in an OMShape? Do you get different results?

You are the first person to write in saying you're using the Cartesian
projection (and I'm assuming, OMShape), how's it working for you?
