hello,
i tried to run command
g.select.pg host=138.232.34.82 database=rsdb
i got following error-message:
Error: select Postgres:FATAL: no pg_hba.conf entry for host
"::ffff:138.232.34.94", user "sabine", database "template1"
what does the required database (rsdb) have to do with database template1?
the following command is working:
psql -d rsdb -h 138.232.34.82 -U sabine
can anyone give me some advice how to continue accessing the database?
thank you, sabine
I have a group of points (vertex of a polygon) and I'd like to link them to
obtain a polygon (vector) to transform it in a rast.
Is it hard to make it?

Simple, r.in.poly.
See the help page for details:
http://grass.ibiblio.org/gdp/html_grass5/html/r.in.poly.html
or v.in.ascii if you really want a vector polygon.

Following up on Hamish's post[GRASSLIST:2756] :
What function would I use to define raster sectors of a circle?
Thanks.

r.digit can do this interactively, or
GRASS 5.0/5.3
v.circle -> v.to.rast
GRASS 5.7
v.buffer (and v.patch for multiples of different sizes)
or 'd.vect.chart ctype=pie' with one data column.
-> v.to.rast
