History

#1 Updated by Giovanni Manghi over 6 years ago

attached another vector that causes the operation to never end (use the "b_floresta" field). In the first attached example you can test the "inters.shp" vector and the "id_grid" attribute.

The input files contain geometry errors. Would it give correct results if those errors are fixed?

at least now it finishes, even if it gives incorrect results (as the inputs have topological issues). But as the original issue is about the tool working at all or not, then this can be closed.
