Hi everyone, I have a vague memory that someone has coded this before, but cannot find it anywhere, but before I code it myself I wanted to know if my vague memory actually was right: I need a module that takes a qualitative raster map (e.g. land cover map) and a vector polygon map and calculates the share of each raster class in each vector polygon. This just means looping of the raster categories, create a reclass map for each category (category = 1 and rest=null) and then use r.univar to calculate non_null_cells/(non_null_cells+null_cells), so it's fairly easy to code, but even so, does anyone know if something like this already exists, before I reinvent the wheel ?
