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

Moin PostGis users,
i want to import huge raster datasets from ArcGis Grid or Erdas
Imagine .img to PostGis (for example DEM25 meters germany around 16
million cells). What is the best way to do that? Found nothing in the
documentation that seems to be practical......(perhaps transform the
grid to points and import the points with the information of the
original cell size and the projection - but that seems to be
circuitous??).
What are you going to achieve with that? Perhaps you could have a look
at the archive of this list and search for raster data and so forth.
There can be found an interesting dicussion about rasters and PostGIS.
Best
Stephan
