[postgis-users] Cost weighted distance raster

ST_Raster2WorldCoordX and ST_Raster2WorldCoordY were replaced with ST_RasterToWorldCoordX and RasterToWorldCoordY in newer version of PostGIS.

Just replace those names in the function and reexecute the CREATE FUNCTION…

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.

Ah thanks. Didn't see the code page. I'll let you know whether these work as is or if they need tweaking.

In the code page :


There is a ST_CostDistance() function.
