FWIW, this is what I'm using on my cycle map: ST_length_spheroid(transform(way,4326),'SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]]') Note the space in "WGS 84". > Is there a difference between st_length() and length()?

Same thing, but the ST_ is the newer version, thought up to distinguih spatial calls. > Postgis manual has a similar query to sum up the length of ways. Why is > it working there? Different projection? I guess it's just an example of the ST_length() function as is, not taking into account any projection issues. -- Lennard _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
