Dear All, I have a linestring that constructed from many points, my question is how can i identify(select) one of the point from the linestring. I know there is ST_POINTN(geometry,integer) that Return the N’th point in the first linestring in the geometry. But with ST_POINTN, i have to know the number of the points in order to return the geometry of the points. is there any other function beside ST_POINTN that can return point geometry without have to know the index number of the points?
I hope all of you can understand my question..thank you in advance -- View this message in context: http://www.nabble.com/select-point-in-linestring-tp21741396p21741396.html Sent from the PostGIS - User mailing list archive at Nabble.com. _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
