I need to assign elevation values to my beach zones from a much more extensive underlying DEM. I could always convert the beach raster to a polygon, then clip the DEM to the polygon extent, but I would rather eliminate that step of the process. Is there a way to assign DEM values to match the extent of my beach raster without such a conversion?</SPAN></BODY></HTML> Tue, 04 Jan 2011 22:24:21 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/assigning-values-from-one-raster-to-another/m-p/584656#M8477 PhilLeckman1 2011-01-04T22:24:21Z Re: Assigning values from one raster to another https://community.esri.com/t5/arcgis-spatial-analyst-questions/assigning-values-from-one-raster-to-another/m-p/584657#M8478 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Hi - <BR /><BR />I have a raster showing locations of beaches along a reservoir that is currently all classified with a single integer value.
