After exploring and removing the outliers, my data is now very close to normal distribution and there is no trend in the data. I now want to perform the variogram analysis and do ordinary kriging for the error values at 218 sampled locations to create error maps.</SPAN><BR /><SPAN>I am not confident enough to analyze the spatial structure of my data, how to fit the variogram model,&nbsp; how to look if there is anisotropy. How to use the tools related variogram fitting properly. I have attached the data also for reference. </SPAN><BR /><SPAN>Any feedback, suggestions is very much appreciated</SPAN></BODY></HTML> Fri, 14 Jan 2011 13:00:09 GMT SudhirKarki 2011-01-14T13:00:09Z Fitting a variogram model https://community.esri.com/t5/arcgis-geostatistical-analyst-questions/fitting-a-variogram-model/m-p/577418#M1294 <HTML><HEAD></HEAD><BODY><SPAN>Hello everyone!!!</SPAN><BR /><SPAN>I am trying to create an error map for 2m LiDAR DEM based on the RTK-GPS measurement points collected from the field.
