Makes sure that any two vertices of the vector layer are at least at distance given by the threshold value.
|
|
|
|
The algorithm moves nearby vertices to one location and adds vertices to segments that are passing around other
|
|
vertices within the threshold. It does not remove any vertices. Also, it does not modify geometries unless
|
|
needed (it does not snap coordinates to a grid).
|
|
|
|
This algorithm comes handy when doing vector overlay operations such as intersection, union or difference
|
|
to prevent possible topological errors caused by numerical errors if coordinates are very close to each other.
|
|
|
|
After running the algorithm some previously valid geometries may become invalid and therefore it may be useful
|
|
to run Fix geometries algorithm afterwards.
