Hello, I hane in my database 6 linestrings and I want to get the boundary rectangle from them (not from each of them)
If i use: select AsText(ST_Boundary(the_geom)) from segments; i get MULTIPOINT(-8.593025208 41.180818082,-8.594827652 41.187632944) MULTIPOINT(-8.594827652 41.187632944,-8.591823578 41.193090782) MULTIPOINT(-8.591823578 41.193090782,-8.611950874 41.190119708) MULTIPOINT(-8.611950874 41.190119708,-8.613796234 41.179203081) MULTIPOINT(-8.613796234 41.179203081,-8.602809906 41.180559684) MULTIPOINT(-8.602809906 41.180559684,-8.593025208 41.180818082) but i need one big Boundary.
