I have a set of features of type
linestring. I'm trying to polygonise the linestrings and assumed that they were closed (naive me :) ). Of course some were not closed and I'm trying to locate the gaps or the endpoints of the individual linestrings, so I can close them manually.
How can I locate the gap in or endpoints of an open linestring?
