Hi, In the past I have successfully been able to fix linestring topology problems (undershoots and overshoots) by using the following approach:
- identify startpoints and endpoints closer to another line less than a given distance; - determine the closest point to that other line; - use a collection of closest points as input to ST_snap, to force the lines to pass on those points. This works fine for 2D linestrings, but know I need to make the Z values of those touching vertexes also match. If I am not wrong, ST_snap only works for 2D, Any ideas of how to assign the same Z to vertexes that have the same XY? Thanks, Alexandre Neto Now, I also need to do it in 3D, any
