Hi all, I am looking for either a "parallel line" feature or "open buffers around a linestring element".
The idea is to visualize a waste-water system where in large map scales the actual diameter of the waste-water pipes (canalization). The linecaps shouldn't be stroked, but the parallel offset to the centerline should be drawn. Are there any tricks how this can be done in Postgis? I see that there is st_buffer, but there is no option to get an open buffer or parallel lines. Thanks for any hints, Andreas -- Andreas Neumann http://www.carto.net/neumann/ http://www.svgopen.org/ _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
