Ben Some additional comments regarding your script. - EBK is a geoprocessing tool and therefore you don't need to 'create' it via the CreateGeostatisticalLayer tool. - if you are creating raster output you can use the environmental MASK which will speed up execution a lot - it appears that your data are in GCS (geographic coordinate system), not a good idea, rather project the data. -Steve ...

What happens if you launch the GA Layer To Grid geoprocessing tool (Geostatistical Analyst tools-> Working with Geostatistical Layers) ? What OS are you running? Thanks Steve ... View more

There are a number of ways to exclude data from the analysis. Here are some; 1) from the Geostats help. "For data formats that support Null values, such as file and personal geodatabase feature classes, a Null value will be used to indicate that a prediction could not be made for that location or that the value showed be ignored when used as input. For data formats that do not support Null values, such as shapefiles, the value of -1.7976931348623158e+308 is used (this is the negative of the C++ defined constant DBL_MAX) to indicate that a prediction could not be made for that location." 2) or use the Make Feature Layer geoprocessing tool 3) or use the Select Layer By Attribute geoprocessing tool -Steve ...

There is a problem with the DEM, it has NoData and �??Not a number�?�. I'm not sure how the NAN values got into the raster. We�??ll fix the hanging issue that you see in our next release, which will most probably be 10.3. To fix your issue, do the following: - RasterToPoint tool - Then use this feature class in place of the raster If you really want to use a raster then: - RasterToPoint - PointToRaster using the original DEM�??s cell size and extent -Steve ...

When creating a DEM from contours one should rather use the TopoToRaster tool. It is designed for that purpose. When converting lines to points and then interpolating the points you'll often get terraces in the output DEM and that is why a more suited tool should rather be used. -Steve ... View more

I'm sorry that you are having a problem. First close ArcMap Please set the GA_TMP variable to a location like c:\temp Then open ArcMap again or reboot your computer or email me at [email protected] -Steve ... View more

It'll be a location similar to C:\Users\xxxxYourNamexxx\AppData\Local\ESRI\Desktop10.0\GeostatisticalAnalyst  (not sure if it is 10.0 or 10 in your case) If you can't find this then set a Windows System Environment variable called GA_TMP -Steve ... View more

After clearing the cache try kriging and if that works then try cokriging BTW, are the points and the raster in the same coordinate system? -Steve ... View more

Sarah You have 13 rain gauges and a DEM with approx. 180x180 rows and columns, correct? - It should have finished, you can kill the process - what version of ArcGIS do you have? - What operating system are you on? - 13 is a very small number of gauges! (but I understand that is all you have) - what type of kriging are you trying to perform? - what transformation have you selected (if any)? - does kriging without the DEM work? - try clearing your cache, viz., close ArcMap, then delete all the files in this location -Steve ...

Trying increasing the bandwidth value. I would rather suggest you first use KernelInterpolationWithBarriers, same concept, larger bandwidth brings in more data, however, it may then over smooth the data. Trial and error and look at using the CrossValidation tool or it can all be done in the Geostatistical Wizard.
