[GRASS-dev] r.sample.category

[Paulo van Breugel]

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
