r.connectivity.distance bugfix

[ecodiv]

• Bugfix resulting in error when using the -p flag
• Correction in example on manual page
• Some small code cleanup

question: can from osgeo import gdal, osr, ogr be replaced by from osgeo import ogr? The gdal and osr do not seem to be used?

Hi, @ecodiv and sorry for the inconvenience. I do have a major update of the module that includes parallel processing. However, when testing my update again, I discovered a bug in v.db.join in 8.4. I plan to post a fix for v.db.join tonight and then create a PR for the new r.connectivity.distance

I'm having trouble getting rpy2 to work on my computer so I was just looking into how difficult it would be to replace the R part in the second module with Python. Is that something which you are (still) considering to do as well?

[ninsbl]

Yes, The R implementation is buggy and not as performant as I wish it would be. I do have a partial replacement of R with Python for r.connectivity.network. Will have a look into it and at least provide you with what I have so far (as I am currently not working on ecology topics...).

[ecodiv]

Thanks, that would be great.

@ninsbl how far are you with this? If you need somebody to test things, let me know.
