A_M Posted March 13, 2014 Report Share Posted March 13, 2014 Hi, I need help to analyze some data. I have a shapefile with several attributes that correspond to polygons. Some of these polygons do not overlap, but others overlap. The polygons have several overlapping case, for example: - A polygon can exactly overlap other, or more than one. - But it may happen that one polygon is overlapped by other polygon in a location and is overlapped by three polygons in another location and in other location it is not overlap by any polygon. So what I want to do is an analysis of overlapping polygons, resulting an image where no overlapping polygons appear green, the polygon that has more than one overlay appear with different kinds of red. And, the polygon having different amounts of overlap would have different shades of red and green (in places where it had not overlap). This has to be possible to do but I 'm having some difficulty. Can anyone help me on this problem? I have done several searches but I did not find the solution. Thanks for your help . Quote Link to comment Share on other sites More sharing options...
Orso8888 Posted March 14, 2014 Report Share Posted March 14, 2014 In your case, if you have only few polygons I will use ArcGIS Topolygy tools, and assign manualy atributes of overlapping. if you have many polygons I recommend you to use ArcGIS Tool "AnalysisTools">"Overlay˙">"Intersect". You will revive overlapping poligons Quote Link to comment Share on other sites More sharing options...
A_M Posted March 14, 2014 Author Report Share Posted March 14, 2014 (edited) Thanks for your answer! I have more than 100 polygons. I will try the overlapping option "AnalysisTools">"Overlay˙">"Intersect". Thanks again! Edited March 14, 2014 by A_M 1 Quote Link to comment Share on other sites More sharing options...
