What happens if the data are in a feature class?. I.e it looks like your input is in a table. If you do, for example, kriging (no cokriging), does it work? Thanks Steve ... View more

Peter Right click on the Geostatistical layer and click on Properties->Method Summary, what is shown? Also, right click on the Geostatistical layer and click on Method Properties, can you step through the Wizard? Thanks Steve ... View more

TopoToRaster in ArcGIS 10.1 can produce larger output rasters than were created pre-10.1 However, we still cannot create huge rasters and it appears that the output size limit was reached in this case. To read more about it please see http://blogs.esri.com/esri/arcgis/2012/08/13/how-large-a-dem-can-the-topotoraster-tool-create/ Regards Steve ... View more

use the ExtractByMask tool on the output ... View more

Justina I'm sorry to hear that you are experiencing problems. Please try the following: - use Spatial Analyst IDW with the points that you are using in SplineWithBarriers - use the same field and cell size and output raster name Does this work? If it does then try SplineWithBarriers with a barrier. Or zip and email ([email protected]) me your dataset, the field you're using and the cell size. Regards Steve ... View more

Jenni You may want to add TopoToRaster to your list of interpolation techniques. I'm pretty sure that it'll out perform IDW. You may also want to look at the SubsetFeatures tool in the Geostatistical Analyst toolbox. With this you can "hide" some data, interpolate and then compare your predictions to the "hidden" values. I.e. model validation. Regards Steve ... View more

In ArcMap, use the Catalog window and browse to the folder where you extracted the zip files. There is a toolbox, expand it and you'll find the script tool. Double click it. Regards Steve ... View more

Why not use TopoToRaster as it was designed from creating DEMs. And BTW, it uses thin plate splines. Steve ... View more

Anke In ArcMap (Python window) or via a Python script, do the following import arcpy arcpy.GetSystemEnvironment('AGSDESKTOPJAVA') Navigate to the folder printed above and navigate further into java\jre\bin do you have java.exe in that folder? Also look and see if you have a system environment variable called AGSDESKTOPJAVA and it'll point to what is printed by arcpy.GetSystemEnvironment('AGSDESKTOPJAVA') Regards Steve ... View more

Julian You'll have to write your own. TopoToRaster, however, has many diagnostic outputs that can be used to assist in fitting a good surface. Regards Steve ... View more

In versions prior to ArcGIS 10 we wrote the output to .shp and then converted to whatever format you wanted. However, from ArcGIS 10 we natively write to the requested format. Therefore, if you're using ArcGIS 10+ you can output to file geodatabase and you won't hit the 2.1GB file limit. Regards Steve ... View more

Ellie We made a big change to TopoToRaster in ArcGIS 10.1. http://resources.arcgis.com/en/help/main/10.1/index.html#/Spatial_Analyst_toolbox/016w00000047000000/ You may also want to look at http://blogs.esri.com/esri/arcgis/2012/08/13/how-large-a-dem-can-the-topotoraster-tool-create/ If you can isolate the problem please send it to me ([email protected]) Thanks Steve ...
