Hi Jason,
Thanks for the quick reply. Your suggestion to rename files to start with a letter worked like a charm. Thanks again!
Cheers,
Karl

Karl,
Thanks for your interest in MGET. We’re glad it is useful to you.
I think the problem is that ArcGIS has some restrictions on the names of GRIDs:
· 13 characters or less
· Only letters, numbers, and the underscore (there might be a few other permitted characters, I just don’t remember)
· Must start with a letter
I think this last constraint might be the problem. Can you rename your GRIDs to start with a letter and try again?
Most other formats (e.g. TIF) do not have such stringent restrictions on the names, so if need flexibility in the names you might have to change formats.
Best regards,
Jason

Hello,
First off, I want to commend you on a great set of tools!
I am currently trying to use the Sample Rasters Listed in Fields to sample values from a GRID raster, but I'm getting an error when the tool runs. I think its not recognizing the raster listed in the field as existing. Is there an extension I need to be putting to the end of the raster path in the field for it to recognize the grid? If I change them to .tif rasters and put the .tif file extension at the end of the path it works great, but I'd prefer to have my rasters as GRID files as they seem to
be smaller file sizes. An example of my raster path listed in the field for the GRID files is:
H:\MODIS_Data\SeasonalRasters\DecadeSnow\101sFalD9999
and for my .tif rasters that work my path looks like this:
H:\MODIS_Data\SeasonalRasters\DecadeSnow\101sFalD9999.tif
So they have the same format with the only exception I've got the file extension listed at the end for the tif files and nothing for the GRID files. Should h
I add an extension for the GRID files? If so what should it be?
