topic Can Kriging be used in planetary analysis in Developers Questions https://community.esri.com/t5/developers-questions/can-kriging-be-used-in-planetary-analysis/m-p/398302#M2602 <HTML><HEAD></HEAD><BODY><P>I am using Kriging for the first time in the analysis of Martian Topography, and previously I have used IDW with success. I am using approximately 5 million points and I appreciate the predictive,&nbsp; iterative nature of this method but it is taking much longer than I would expect ( 6 hours +). I have looked the session progress and I see the Geographical transformations to be NAD and some&nbsp; of its variants, I would have expected the Martian Coordinate System equivalent to the data frame to be here. The points&nbsp; are GCS_Mars_2000_Sphere and the Projected Coordinate System Mars 2000_Equidistant cylindrical. Could this disparity be the cause of the excessive execution time?</P></BODY></HTML> Tue, 20 Nov 2018 21:26:33 GMT BrianKneller 2018-11-20T21:26:33Z Can Kriging be used in planetary analysis https://community.esri.com/t5/developers-questions/can-kriging-be-used-in-planetary-analysis/m-p/398302#M2602 <HTML><HEAD></HEAD><BODY><P>I am using Kriging for the first time in the analysis of Martian Topography, and previously I have used IDW with success.
