I added the code to be able to add polygons to the example... It created the following output...

I was looking for g.write and can't find that to see what it is looking at to generate the data in the variable "data". How do I use this in order to save and put these polygons back into the polygon layer??? Honestly, I don't know what this object is that I'm looking at. My goal is to dynamically generate the polygon from other code I've already written and insert it into the polygon layer. Then when the cursor is hovered over the polygon, I can display data associated with the polygon. Thanks, Robert J Becraft. _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
