Then use the build footprints tool. Set maximum data value to 254 and number of vertices to 20. Tick the maintain sheet edges, Tick Overviews and Update Boundaries boxes. Run the tool. Then bring the mosaic into arcmap and export the boundaies as a shapefile. </SPAN><BR /><BR /><SPAN>Let me know if this works for you.</SPAN></BODY></HTML> Mon, 03 Mar 2014 07:15:35 GMT https://community.esri.com/t5/data-management-questions/how-to-create-polygon-shapefile-shp-from-an/m-p/399884#M22915 DXXX 2014-03-03T07:15:35Z Re: how to create polygon shapefile(.shp) from an satellite image https://community.esri.com/t5/data-management-questions/how-to-create-polygon-shapefile-shp-from-an/m-p/399885#M22916 <HTML><HEAD></HEAD><BODY><SPAN>Here is what I did, it´s well explained in this video:</SPAN><BR /><BR /><A href="http://www.youtube.com/watch?v=RlPsJyyy6eE">http://www.youtube.com/watch?v=RlPsJyyy6eE</A><BR /><BR /><SPAN>1) Create signature</SPAN><BR /><SPAN>2) Then Maximum Likelihood Classification (SA)</SPAN><BR /><SPAN>3) Convert �??Raster to Polygon�?�</SPAN></BODY></HTML> Tue, 04 Mar 2014 06:26:51 GMT https://community.esri.com/t5/data-management-questions/how-to-create-polygon-shapefile-shp-from-an/m-p/399885#M22916 AnneKuellig 2014-03-04T06:26:51Z Re: how to create polygon shapefile(.shp) from an satellite image https://community.esri.com/t5/data-management-questions/how-to-create-polygon-shapefile-shp-from-an/m-p/399886#M22917 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Here is what I did, it´s well explained in this video:<BR /><BR /><A href="http://www.youtube.com/watch?v=RlPsJyyy6eE">http://www.youtube.com/watch?v=RlPsJyyy6eE</A><BR /><BR />1) Create signature<BR />2) Then Maximum Likelihood Classification (SA)<BR />3) Convert �??Raster to Polygon�?�</BLOCKQUOTE><BR /><SPAN> </SPAN><BR /><SPAN>Nice one. Keep my method in mind because when you start using the raster to polygon tool on larger data sets the tool will fail.
