Sorry, I now see that I can just export each CV point table as part of a new feature layer for each iteration. Is there a way to combine all of the summary CV statistics into a table or other format?

Hi Steve. Thanks for the hint!... that was helpful. The Cross Validation GA utility tool seems to provide the summary statistics as values and the option to append the point CV to a point feature layer. Since I will be iterating over my input points and selecting subsets, it seems that exporting to the input points feature layer is not possible. I would like to 1) Store the summary CV statistics for each iteration in a table or other output and 2) save the table of CV statistics per point. Are these tasks beyond Model Builder? If not, can you steer me toward how I can do them?

Thanks for the comment, Steve. I have ultimately switched to using EBK, so the projection issue is not a problem. I have another question, however. I would like to export the CrossValidation result table for each surface created in my Model Builder model to use for further assessing the resulting surface. Do you know of a way to automate export of this table in Model Builder?

I was able to resolve my problem by setting additional variables both for the environment and the tool. Specifically, I added the target raster as an element in the model. I then used the 'Connect' tool to link it to the 'GA Layer to Grid' model object and set: 1) Snap raster environment variable, 2) Extent environment variable, 3) Cell size tool parameter and 4) Cell size environment variable. I don't know if the order has any effect (it shouldn't), but this process gave me output rasters with the proper resolution and extent matching the target raster.

I have a geostatistical layer created using ordinary kriging and the 'Create Geostatistical Layer' tool in Model Builder. I am trying to output this layer to a raster that matches a target raster using the 'GA Layer to Grid' tool. I have used the target raster to set the 'Snap Raster', 'Cell Size', and 'Processing Extent' environment variables and various logical combinations of these variables. However, the raster that is output has one additional row at the top when compared to the target raster. This row is filled with NoData values. The target raster has these dimensions: Columns_and_Rows: 110, 166 Cell_Size: 0.11559105, 0.11559105 Extent: Top 49.359975678 Left -129.652945807 Right -116.937930333 Bottom 30.1718614184 Spatial_Reference: CS_WGS_1984 The output raster has these: Columns_and_Rows: 110, 167 Cell_Size: 0.11559105, 0.11559105 Extent: Top 49.4755667278 Left -129.652945807 Right -116.937930333 Bottom 30.1718614184 Spatial_Reference: CS_WGS_1984 Why does my raster have an extra row (and therefore the wrong Extent) and how can I fix this?

I figured out the solution. You can use the 'Calculate Value' tool from the 'Insert'>>'Model Builder Tools' menu with the iterator 'Name' variable as an input. Adding the python script "%Name%"[4: ] will return the character string minus the first 4 characters. You can then use the result of the tool as your inline variable for naming.

Hi- I have a model using the 'Iterate Feature' tool. I am using the %Name% inline variable from the iterator to name my output files. The %Name% variable takes on the values "All_2014_06", "All_2014_07",.. etc. I would like to name my files with "Speed_2014_06", "Speed_2014_07", etc. instead... is there a way to alter the %Name% variable or only use a subset of the variable (the date portion) to do this?

OK. Thanks for your help, Eric!

Great! I wasn't certain, but thought this might be the way to do it. Thanks for confirming, Eric! I have another question about model builder, if you don't mind. I am using the %Name% inline variable from the iterator to name my output files. The %Name% variable takes on "All_2014_06", "All_2014_07",.. etc. I would like to re-name with "Speed_2014_06", "Speed_2014_07", etc. instead... is there a way to alter the %Name% variable to do this? Thanks!

Hi- I have built a model in Model Builder that iterates over point Features in a file geodatabase, selects a subset of each point feature based on attributes and then uses the 'Create Geostatistical Layer' tool to implement Ordinary kriging with optimization via crossvalidation. I am using an xml file as a template. I attached a screenshot of the model for reference. I would like the output to be 1) a raster of predictions and 2) a raster of Standard Errors. I have used the 'GA Layer To Grid' tool to output the prediction raster. However, the type of output from the 'Create Geostatistical Layer' tool is specified in the xml file. Do I need to re-run the tool with a new xml template in order to output the SE raster or is there a simpler way to do this. (This is simple to do when a GA Layer is created with Geostatistical Analyst by right clicking the layer and selecting 'Change output of Standard Error'). I am using ArcGIS 10.3.1 for Desktop with the Advanced license on Windows 10. I also have 64-bit Background Geoprocessing installed in case that is relevant. I used some of the information from this (Automating geostatistical interpolation using template layers | ArcGIS Blog) post by Eric Krause and this (https://community.esri.com/thread/80709 ) to get started.
