[GRASS-web] r.sample.category errors

Hi Mitchell,

The problem is that the input map starts with a number. I am actually surprised GRASS accepted that map name...
The database management at least does support column names starting with numbers (here 2016) and throw an error.

Renaming the input map should fix it, I guess...

Hope that helps.


P.S.: grass-user at lists.osgeo.org<mailto:grass-user at lists.osgeo.org> is more suited for that kind of questions.... There you reach more people who could answer that kind of questions...

Subject: [GRASS-web] r.sample.category errors

Good afternoon GRASS GIS developers,

I'm currently trying to run the futures extension through GRASS GIS and have been following the wikipages manual on how to complete the exercise but I'm having an error with the r.sample.category module and am curious if one of you could point me in the right direction.

I've developed all the necessary predictor rasters and the response variable raster for my study area but the module is giving me the same error, no matter what kind of troubleshooting I attempt. I thought that maybe I had to reassign my null and integer values but even after I tried that, I couldn't get the tool to run. It gives me this "Error while executing: "CREATE TABLE output_filename (cat integer, input_filename integer).

I've attached a screenshot of the command output so you can see all the messages GRASS GIS gives me but I'm not sure what the issue could be. If you could please assist me, that would be greatly appreciated!
