I have a geodatabase with a given number of polygon features. I would like to generate a layer (V) that displays the number of overlapping polygons at any given (x,y) location spanned by my polygons. For example, if at (x1,y1) I have two overlapping polygons my V(x1,y1)=2, if I have no polygons at (x2,y2) then V(x2,y2)=0, and so on. What is the easiest way to build this map? I am currently reviewing join and merge tools to see how I can make this work.
I know this is an older post but I had a similar problem and found this tool http://www.arcgis.com/home/item.html?id=1dd4a6832b3d40b494dbf8521cc5134c, was the easiest solution.
using union and dissolve i was able to get it to work, the key for me was to select the right Dissolve_Field to Count over in the Statistics Field (i.e. both fields match and I used "shape_Area" as the unique indentifier). Thanks for the comments! This post was most helpful for me: Counting and rasterizing polygon overlaps in ArcGIS Desktop?
