That's hard to say from this, check whether the v.extract gives any
warning and if it extracts any features.

Re: [GRASS-user] v.to.rast error in version 7.0.6svn
Anna,
I run the command you suggested and there is indeed a connection problem.
How do i fix it? Here are the commands i run in a grass/python script:
criteria="(value=255) and (area_sf>"+sys.argv[5]+")"
grass.run_command('v.extract', input='imperv',
output='impervh_clean',type='area',where=criteria)
Here is the command yielding the database connection error...
grass.run_command('v.to.rast', input='impervh_clean',
output='impervh_clean1',use='attr',attribute_column='value')
Any suggestion to establish db connection for vector map "impervh_clean"?
Regards,
Alassane

Re: [GRASS-user] v.to.rast error in version 7.0.6svn
Anna, is that the command needed to make the connection? ... db.connect driver=sqlite database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db' db.tables -p v.db.connect map=vectormap table=table driver=sqlite \ database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db' v.db.connect -p map=vectormap Thanks, Alassane On Tue, Oct 18, 2016 at 9:46 PM, Anna Petrášová wrote: > > > On Tue, Oct 18, 2016 at 9:31 PM, alassane toure wrote: > >> Group, >> While executing v.to.rast the following error came up (not present in >> earlier 7.0 version) >> Your suggestion is appreciated. >> > > Check your database connection for the input vector, it says: > "Database connection not defined for layer <1>" > > using v.db.connect -p vector_name > > Anna > > >> Thanks >> Alassane >> >> ___ >> grass-user mailing list >> grass-user@lists.osgeo.org >> http://lists.osgeo.org/mailman/listinfo/grass-user >> > > ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
