Hello to everyone, i'm using Grass 6.4.0 with the purpose to compute the average value of a raster for each polygon of a vector in the same boundingbox. Theese are the steps: - Improve resolution from 200x200m to 5x5m - Rasterizing the vector map using cat column as identifier - Computing r.average using the raster map of a particular phenological situation and the rasterized vector map
Everything seems work well, till i found that the computed value of the r.average is different by a constant (-19.6137256622). This value is added to every computed mean in the raster map, and i don't understand the reason of this weird behavior. I wish you could help me.
