I am having a look at the new r.sample.category addon. Great idea. I would like to make a suggestion; to allow the user to define the number of points as a percentage, similar to r.random.

do you mean number of points should be based on percentage of cells in each

category or the entire raster? There are some other TODOs in

https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.sample.category/r.sample.category.py#L47

Hi Anna

I was thinking about the option for the user to (1) define a separate percentage for each category or (2) one percentage for the whole raster (e.g., 10% → 10% of cells in each category is sampled).

If you implement the second option, you would more or less have your 6th TODO (specify number of points and distribute them according to histogram) I guess?

Cheers,

Paulo
