[GRASS-user] OSM, v.kernel, raster combination, id begint

Hello GRASS-Users,

I want to analyse the OSM data with GRASS (6.4.0RC5+39438) / Ubuntu 10.04.4 LTS / PostGIS-database. I want to use the v.kernel function to create a density raster. In addition I want to combine this density-raster with a population density raster. I hope to find a correlation between the OSM density and the population density. There are anybody who have an idea to realize this raster-combination?

Another issue is the problem with the OSM object identifier in begint-dataype. GRASS only supports integer id's! Is it possible to modify GRASS?

Thank you!
Christopher

Please note that this seems to be a pretty antique GRASS GIS version...

Please use GRASS GIS 7:
http://grass.osgeo.org/download/software/linux/
--> Precompiled GRASS GIS 7.svn
  ---> Ubuntu

GRASS 7 comes with Large File Support, see
http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Libvector

Hope this helps,
