I don't know how you would make the decision as to which H/V to convert to which diagonal values. I assume you may get some very strange results.</SPAN></BODY></HTML> Fri, 09 Mar 2012 18:51:46 GMT MarkBoucher 2012-03-09T18:51:46Z Stream network from flow accumulation whihc is based on d4 flow direction https://community.esri.com/t5/water-resources-questions/stream-network-from-flow-accumulation-whihc-is/m-p/572668#M2940 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>how can I generate stream network from flow accumulation whihc is based on d4 flow direction.</SPAN><BR /><SPAN>I want to avoid diagonal connections in rivers.</SPAN><BR /><BR /><SPAN>Thanks</SPAN></BODY></HTML> Fri, 09 Mar 2012 12:16:10 GMT https://community.esri.com/t5/water-resources-questions/stream-network-from-flow-accumulation-whihc-is/m-p/572668#M2940 TaiseerHarb 2012-03-09T12:16:10Z Re: Stream network from flow accumulation whihc is based on d4 flow direction https://community.esri.com/t5/water-resources-questions/stream-network-from-flow-accumulation-whihc-is/m-p/572669#M2941 <HTML><HEAD></HEAD><BODY><SPAN>If I understand what you are wanting to do, all I can think of, off the top of my head, is you'd have to create the fdr using the 8 directions in arc hydro and then use the raster calculator to convert the diagonal grid values to some other horizontal of vertical (H/V) grid value.
