Hi,
ok, now a little bit simplified (table parameter)...
I imagine this means that you are obliged to call your key column 'cat' ?

# create table containing transformation parameters
echo "create table archsites_t (cat int, zs double)" | db.execute
# insert transformation parameters for category 1
echo "insert into archsites_t values (1, 1000)" | db.execute
# insert transformation parameters for category 2
echo "insert into archsites_t values (2, 2000)" | db.execute
# perform transformation
v.transform -t input=archsites output=archsites1 column="zshift:zs"
table="archsites_t"
# drop table contaning transformation parameters
echo "drop table archsites_t" | db.execute

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

Dear list,
Is there a way to "extrude" 2D vector points to 3D points based on
attribute column values, similar to what I have read v.extrude can do
with lines? I have tried to use v.extrude with points but an empty 3D
vector was created.
Thanks and regards,
Luigi
