Re: [OpenMap Users] Question Regarding an Error Message When Loading Shapefiles

Hi Erich,

The layers do not show street names as they are written. To get that
to happen, you'll have to write the code to create OMText objects from
the dbf files, and then use the corresponding geometries from the shp
to figure out where to put them (the OMText). The
com.bbn.openmap.plugin.esri.EsriPlugIn is an example of using the
DbfTableModel object to read the dbf file.

You might want to look at the com.bbn.openmap.layer.shape.areas
package, and check out the AreaHandler. It does work in matching up
the geometries with the dbf file contents, too. But there isn't any
code in place to actually lay out the text on the map.

Regards,

- Don
