topic Smoothing in Topo to Raster in 3D Questions https://community.esri.com/t5/3d-questions/smoothing-in-topo-to-raster/m-p/266883#M1604 <HTML><HEAD></HEAD><BODY><SPAN>Hi guys,</SPAN><BR /><BR /><SPAN>I've been doing some surface interpolation with the Topo to Raster function in ArcGIS and I had a few questions I was hoping someone could help with. The data I am using is relatively noisy and potentially overconstrained and so the surface I have produced has come out somewhat "bumpy". I was hoping to smooth this out a bit but I wasn't entirely sure what changes to make to the settings. I imagine that it will be the Roughness penalty and/or Profile curvature roughness penalty options which would make the difference but I wasn't exactly sure what values to use either. Any help/advice would be greatly appreciated.</SPAN><BR /><BR /><SPAN>Regards</SPAN><BR /><SPAN>Robin</SPAN></BODY></HTML> Thu, 06 Mar 2014 03:51:57 GMT RobinLee1 2014-03-06T03:51:57Z Smoothing in Topo to Raster https://community.esri.com/t5/3d-questions/smoothing-in-topo-to-raster/m-p/266883#M1604 <HTML><HEAD></HEAD><BODY><SPAN>Hi guys,</SPAN><BR /><BR /><SPAN>I've been doing some surface interpolation with the Topo to Raster function in ArcGIS and I had a few questions I was hoping someone could help with.
