[postgis-users] import of Raster data

[Andreas Laggner]

Moin Stefan  ;-)

i want to use the spatial data from the raster together with vector data 
in postgis. For example: soils from buk1000 and preception from DWD 1km 
raster or altitude/slope from DEM25m raster to analyse potentials of 
farmland.
I need the values from the cells in a spatial correct topology.
In the year 2007 the archive did not have any solutions for raster data 
import.......

hasta luego      Andreas
