[GRASS-user] extrude vector points

[Martin Landa]

Hi,

now in CVS possible also using v.transform.

Martin

E.g.

# create table containing transformation parameters
echo "create table archsites_trans (cat int, zs double)" | db.execute
# insert transformation parameters for category 1
echo "insert into archsites_trans values (1, 1000)" | db.execute
# insert transformation parameters for category 2
echo "insert into archsites_trans values (2, 2000)" | db.execute
# connect table contaning transformation parameters
v.db.connect archsites layer=1 table=archsites_trans -o
# perform transformation
v.transform in=archsites out=archsites_t col="zshift:zs"
# reconnect original table
v.db.connect archsites layer=1 table=archsites -o
# drop table contaning transformation parameters
echo "drop table archsites_trans" | db.execute
