A good approximation would be fine. It would be necessary to write in C for efficiency reasons and because C library functions need to be heavily used. Additionally, search structures like balanced binary search trees and min heaps are needed which are already implemented in GRASS as C code. I have already written 2 different C modules trying to extract the medial axis, both are incredibly complex and none of them works properly. I am familiar with GRASS, C, and Python and like to use the easiest approach. In this case I am pretty sure that the easiest and most appropriate approach is using C, not Python. Therefore I would recommend a good knowledge of C and some knowledge of the GRASS C API for this project. Markus M > > And one more question.
