Rengifo: 1) import
v.in.ogr dsn=your.shp out=vector

2) new column to database table
v.db.addcol map=vector columns=”slope DOUBLE,aspect DOUBLE”

3) get the values
v.what.rast vect=vector raster=slope column=slope
v.what.rast vect=vector raster=aspect column=aspect

Hi Jachym,
I am newie to GRASS GIS. So, I hope my questions are not to simple.
DATA AND PROBLEM DESCRIPTION: I have a SRTM -DEM, which I used to calculate slope and aspect. I also have ground control points (GCP) over the area. The GCP´s are in shape format.
QUESTION
How can I extract raster values per location (point) in GRASS GIS?
The Idea behind of it is that I want to compare
slope, aspect, GCP,and SRTM -DEM values to determine the slope/aspect error dependency of the SRTM-DEM

Thanks in advance
Rengifo

Wonderful Jachym!
I wait your ready-steady-go to install it :-)

It should be at the server by now – let me know, if it works.

I’ll wait for it :-)
If you plan to package it within a month I’ll avoid recompiling it…

Hi Jachym.
Is it in your schedule the packaging of Mapserver 5 for the gutsy repo?

Any plan to make 64bit packages too ?

Jachym, at first thanx for the repository!!
As I’ve seen Emanuel also has some problems running QGIS 0.9 on 7.10 64-bit system. In my case I can install the grass-plugin but after that there exists a dependency problem between libgdal and the grass-plugins. The same problem exists if do install qgis 0.8 on my gutsy 64-bit system. Seems somehow strange…

#10 Anne: ahhgr, sorry, I did not prepare the packages for amd64 yet.

However, since sources are there, you can compile and install them easy.

apt-get source grass
cd grass-6.2.2…
dpkg-buildpackage -rfakeroot # fix missing packages
dpkg -i ../*.deb
