topic Merge Adjacent/Connected Polygons in Data Management Questions https://community.esri.com/t5/data-management-questions/merge-adjacent-connected-polygons/m-p/80706#M4682 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I have an output that has 400000+ features in the polygon and I need to find the areas that have a certain size. I have noticed that the polygons that are adjacent/connected to each other are different features in the shapefile and I would like to merge the features that are connected to one and other. The output has various polygons that were merged together. Areas appear to be connect but when selected 10 features make up 1 large area that appears to be connected. </SPAN><BR /><SPAN>Any help would be great. </SPAN><BR /><BR /><SPAN>Thanks</SPAN></BODY></HTML> Thu, 16 Feb 2012 17:40:34 GMT ChadMahoney 2012-02-16T17:40:34Z Merge Adjacent/Connected Polygons https://community.esri.com/t5/data-management-questions/merge-adjacent-connected-polygons/m-p/80706#M4682 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I have an output that has 400000+ features in the polygon and I need to find the areas that have a certain size.
