[postgis-users] Cost weighted distance raster

[Spencer Gardner]

Just to follow up:

I was able to execute the CREATE FUNCTION scripts with some minor tweaking.
When I run ST_CostDistance it chokes on making a call to
ST_World2RasterCoordx. That's as far as I've gotten. I'll have to turn my
attention to another solution for now.

It's a shame--having a good cost and raster routing library would be very
nice to have.

Thanks for your help.
