topic How to select from overlapping polygons? in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/how-to-select-from-overlapping-polygons/m-p/163722#M5521 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I have a polygon dataset which have around 70% overlapping polygons. The overlap is designed to store data for a variety of polygon types. For instance, 5% of a polygon has Aspen trees and 95% of that polygon has Willow trees. I want to use one polygon per one type of data. I would like to see the polygons that have the maximum percentages of tree cover. My new shapefile will be free from overlapping polygons and each polygon will have a single attribute of percent of tree cover. I was thinking of selecting by attributes; what should be the syntax? Does ArcGIS have any 'If' function? How might I have this question solved? </SPAN><BR /><BR /><SPAN>Thanks for considering,</SPAN><BR /><SPAN>Sharif</SPAN></BODY></HTML> Tue, 18 Mar 2014 01:01:12 GMT SharifIslam 2014-03-18T01:01:12Z How to select from overlapping polygons? https://community.esri.com/t5/geoprocessing-questions/how-to-select-from-overlapping-polygons/m-p/163722#M5521 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I have a polygon dataset which have around 70% overlapping polygons.
