This page explains overlapping map features within one map layer. Also see Overlapping Layers in MapGuide for overlapping layers that are on top of each other.
Some Improvement Plan areas in this sample map overlap. You can guess which ones, but do you know for sure?
There is no way to know and identify the mapped plan areas without selecting the area of interest and getting a report. You'll be surprised to see what overlaps -- and what doesn't.
You can experiment with overlaps using the Improvement Plan MapGuide Map. Be sure to zoom in to see the "Improvement District Plans - Pima County" layer.
How do I get information for overlapping map features in one map layer? - The short answer:
First, be sure MapGuide's selection mode is set to "Intersection". (Right-click in the map area, choose Preferences..., pick "Intersection" in the Selection Mode area and pick OK.)
