In your case the CONdition is if raster1 (slope) &gt; 10 then raster2 (isopach). This will give you a new raster output with all the values where slope is greater than 10.</SPAN><BR /><BR /><SPAN>Robert</SPAN></BODY></HTML> Wed, 15 Sep 2010 16:11:28 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/raster-to-raster-calculations/m-p/320923#M4519 RobertBerger 2010-09-15T16:11:28Z
