Try using ST_StartPoint and ST_EndPoint, which can be used in self joins of linestrings. These functions can identify (e.g.) stream confluences, where one start point meets more than one end point. Also, these functions can be made faster with a functional index. _______________________________________________ postgis-users mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/postgis-users
