I know the Spatial Join tool functions when using two shapefiles, but not when one map is a raster file. </SPAN><BR /><SPAN>For the sake of accuracy I prefer to not convert the shapefile into a raster file. </SPAN><BR /><SPAN>What tool can I use to solve my problem?</SPAN></BODY></HTML> Mon, 26 Mar 2012 09:18:44 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/combine-raster-with-shapefile/m-p/3690#M64 WouterNelis 2012-03-26T09:18:44Z Re: Combine raster with shapefile https://community.esri.com/t5/arcgis-spatial-analyst-questions/combine-raster-with-shapefile/m-p/3691#M65 <HTML><HEAD></HEAD><BODY><SPAN>I would recommend using the </SPAN><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z000000w8000000.htm">Zonal Statistics as a table</A><SPAN>, then take the table and join it back to the polygons.
