Hi, my problem is - I have polygons defined as a set of coordinates with assigned categories and I want to create vector areas where the centroid would have that category. I don't want to use PyGRASS because of ctypes. I wanted to write an ascii file (ascii vector format) but it allows me to write only boundaries and centroids (not areas). But I don't have centroids. So I can write boundaries and then use v.centroids afterwards but I don't know how to specify the correct category values for those new centroids. There doesn't seem to be any way to transfer categories from boundaries to centroids. So, am I missing something? Why vector ascii format doesn't support areas? Would it be difficult to add it?
Thanks, Anna
