I'm fairly new at GIS and having some problems getting some polygons to do what I want them to! Basically, I have two sets of polygons - a set of large polygons representing watersheds, and another set of smaller polygons representing buildings, roads, etc (impervious surfaceS). I'm trying to find the total area of these smaller polygons within each of my watersheds. </SPAN><BR /><BR /><SPAN>I've tried the Merge tool, with some success. However, I believe with polygons that share a watershed it only assigns the polygon to one of the watersheds. As some of my polygons are large (ie. roads)and shared between multiple watersheds, this isn't working to well.</SPAN><BR /><BR /><SPAN>What I'd really like is for polygons that span two or more watersheds to be broken up between them. Does anyone know how I could do this?</SPAN><BR /><BR /><SPAN>I am using ArcMap 10.</SPAN><BR /><BR /><SPAN>Thanks</SPAN><BR /><SPAN>aaron</SPAN></BODY></HTML> Mon, 12 Sep 2011 07:54:38 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/polygons-within-polygons/m-p/642125#M9291 AaronHodges 2011-09-12T07:54:38Z Re: Polygons within polygons https://community.esri.com/t5/arcgis-spatial-analyst-questions/polygons-within-polygons/m-p/642126#M9292 <HTML><HEAD></HEAD><BODY><SPAN>I would consider using the </SPAN><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00080000000s000000.htm">Union</A><SPAN> tool to create the new feature that would split the polygon across the two zones.&nbsp; Then you should be able to process each building.</SPAN></BODY></HTML> Mon, 12 Sep 2011 11:18:10 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/polygons-within-polygons/m-p/642126#M9292 JeffreySwain 2011-09-12T11:18:10Z
