I'm confused about how grass decides what is an area with a centroid, and what is a boundary with a point inside it. I am using v.in.ascii to import a text file in standard mode. The file contains two circles (boundaries) and two points (their centroids). The circle boundaries overlap. I have notices that if the circles are close together, so that the center point of one is with the boundary of the other, I end up with one circle that is an area with a centroid, and a non-area boundary and a point. If the circles are a little further apart, I get two areas and their corresponding centroids.
I need both circles and their center points to import as areas with centroids, no matter how close together they are.
Can anyone explain what's going on here?
Thanks,
