Hy everbody,

i am having following problems using GRASS 6.2.0 :

  1. When Digitizing in GRASS, my GRASS hangs in between and X Monitor and Digtizing Window also stop responding. I have to stop the grass session and kill the appropriate processes inorder get things going again. What might be the cause for this???

  2. I’ve also heard about running QGIS from inside GRASS. What QGIS & GRASS versions are required for the purpose? becuase my GRASS dosent support this.

  3. What is the purpose of CAT valules in the database table of the vector files??

  4. Can someone also mail me exact step of installing Cygwin and then GRASS on it on windows XP? Also i need the link for latest GRASS rpm’s.

Thanks in Advance.

Hy everbody,

i am having following problems using GRASS 6.2.0 :

1. When Digitizing in GRASS, my GRASS hangs in between and X Monitor and
Digtizing Window also stop responding. I have to stop the grass session and
kill the appropriate processes inorder get things going again. What might be
the cause for this???

2. I've also heard about running QGIS from inside GRASS. What QGIS & GRASS
versions are required for the purpose? becuase my GRASS dosent support this.

you have to install qgis with support for GRASS (so QGIS supports
GRASS, not GRASS supports QGIS). In debian-based distros, there are
packages with the GRASS plugin for QGIS avaliable. I have no idea, how
this is organized in RPM-based distros. If you compile QGIS by
yourself, you have to use --with-grass option for ./configure

3. What is the purpose of CAT valules in the database table of the vector
files??

CATegory value is uniqe ID, which connects vector objects to database
records. More about GRASS vector format in
http://www.ing.unitn.it/~grass/conferences/GRASS2002/proceedings/proceedings/pdfs/Blazek_Radim.pdf

4. Can someone also mail me exact step of installing Cygwin and then GRASS
on it on windows XP? Also i need the link for latest GRASS rpm's.

Thanks in Advance.

Usually, the GRASS-OGR-GDAL plugin is a separate RPM package.
