Hi all, I am using QGIS with PostGIS with the data that represents some cables on the terrain. There are some segments where the cables are drawn one near another (for example about 30 cm apart) and they even cross sometimes. My goal is to get the trenches, so to "merge" those parts of lines, that are separated for example for 50 cm at most into one so that later I can get the length of the trenches required (in the cases where lines are separated for less than 50 cm, of course one trench will be planned and it should be in the middle of both lines with the defined width).
What would be the best procedure to follow to achieve this? I have tried ST_Equals and ST_HausdorffDistance, but I can't get on the right track ... Thanks, Matej _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
