[postgis-users] Nearest point on an linestring

[skoehler at buschjena.de]

Hello,

with the distance function I can compute the distance between an 
linestring and an point. But how can I compute the nearest point on the 
linestring to my query point?
I think the distance function needs this point also and so the information 

is in the system, how can I use it?

Thanks 
Steffen
