I came accross the following paper:</SPAN><A href="http://www.hydrol-earth-syst-sci.net/14/1153/2010/hess-14-1153-2010.pdf" rel="nofollow" style="font-size: 14px; color: #4a6b82; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; background: #ffffff;">http://www.hydrol-earth-syst-sci.net/14/1153/2010/hess-14-1153-2010.pdf</A><SPAN style="color: #000000; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; font-size: 14px;"> by THengl 2010. The auther used point datasets to generate the DEM and to generate the variogram model. I've got very little experience in Geostatistics and need help\advice from the community if I can apply the following by converting my DEM to points for the variogram model. Two of the three DEMs will be generated from contours (generated from stereo images and 3D river centrelines), the third DEM is the hydroSHEDS STRM 90m DEM. The reason for choosing the following is based on the current research that I've done so far and determining the uncertainty within the location of the generated river network from two flow routing algorithms (SFD = Single Flow Direction and MFD = Multiple Flow Direction).</SPAN></P></BODY></HTML> Mon, 22 Sep 2014 20:16:11 GMT https://community.esri.com/t5/spatial-data-science-questions/conditional-sequential-gaussian-simulation/m-p/578708#M1293 PeterWilson 2014-09-22T20:16:11Z Re: Conditional Sequential Gaussian Simulation https://community.esri.com/t5/spatial-data-science-questions/conditional-sequential-gaussian-simulation/m-p/578709#M1294 <HTML><HEAD></HEAD><BODY><P>Peter...
