/hello
I want to create vector points from DEM in regular spaces.
Say, in every 10 m, I want to pick height values from DEM and
create the vector map with db table.
As far as I see, ///v.random <cid:part1.09040903.01070903@deprem.gov.tr>
makes in irregular spaces.
Right.
What do you offer me to do ?
g.region ... to set region boundaries and coordinates,
r.to.vect with feature=point parameter
Spearfish example:
g.region -dp
r.to.vect elevation.dem out=elev feature=point
d.mon x0
d.vect elev
v.db.select elev
cat|value|label
1|1112|
2|1111|
3|1111|
4|1110|
...
The value column contains the elevation.

thank you
I will try your way.
After I sent my mail.
I think I solved the problem with
r.stats -gn input=map1,dem ( it enables me to exclude null values and
confide to my map features (map1) )
then I am trying to import resulting text file to grass.
