Thanks Barend, the function you mentioned is just what I needed. I have implemented it on my own. Sadly, only the brute force approach using for_each_segment and adding up the length travelled. Great lib nonetheless. Cheers, Stephan On Fri, May 25, 2012 at 1:14 PM, Barend Gehrels <barend@xs4all.nl> wrote:
There is no such function built in. You are probably looking for a function as LocateAlong, http://postgis.refractions.net/documentation/manual-2.0/ST_LocateAlong.html
This function is (ever) planned, it is part of the OGC SF specification. But it is not there yet.
