I would like to fill these holes by interpolating the values. Is there a way to do this? Further, if possible I would like to interpolate out to the edge of my shoreline polygon (depth = 0). I'm at a loss at how to do this.</SPAN><BR /><BR /><A href="http://img.photobucket.com/albums/v211/Matrix-D/Columbia.png"><IMG src="http://img.photobucket.com/albums/v211/Matrix-D/Columbia.png" /></A></BODY></HTML> Mon, 07 Nov 2011 21:10:31 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/filling-holes-in-a-raster/m-p/718006#M10432 DrewLindow 2011-11-07T21:10:31Z Re: Filling holes in a raster https://community.esri.com/t5/arcgis-spatial-analyst-questions/filling-holes-in-a-raster/m-p/718007#M10433 <HTML><HEAD></HEAD><BODY><SPAN>The </SPAN><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z00000050000000.htm">Fill</A><SPAN> tool is used to fill in the gaps between values and depending on the inputs it will determine what will be changed.&nbsp; If you are looking to digitize the shoreline, then I would use the Raster Domain tool in 3d Analyst to create a polygon along the edge.&nbsp; Then I would use the </SPAN><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//009z000000m8000000.htm">IsNull</A><SPAN> and then </SPAN><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Con/009z00000005000000/">Con</A><SPAN> statement as described </SPAN><A href="http://blogs.esri.com/Support/blogs/supportcenter/archive/2011/08/02/null-doesn-t-mean-zero.aspx">here</A><SPAN>, with the polygon created before used as the </SPAN><A href="http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001w0000001t000000">Mask</A><SPAN> in the Environment Settings.&nbsp; That way the values inside the polygon should be converted to 0 and then only the internal edges will be filled in.&nbsp; Another way would be to use the Con(IsNull("raster"),FocalStatistics("raster",NbrRectangle(4,4),"MEAN"),"raster").&nbsp; So there are a few ways to accomplish based on which ones you want to change.</SPAN></BODY></HTML> Wed, 09 Nov 2011 10:57:30 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/filling-holes-in-a-raster/m-p/718007#M10433 JeffreySwain 2011-11-09T10:57:30Z
