Hi all,

With a table of x, y znd z points can I have the correspondent map? Is this
possible with GRASS? How can I make it?
Thanks!

Best Regards,

=======================================

Yes, if you have a database table (dbf), you can use v.in.db; if you have a
plain ascii text file, use v.in.ascii.

Hope this helps,

Dear all,

I have for example the following text file called teste:

x y z
1 2 3
2 3 2
4 5 1
3 1 2

I tried
$ v.in.ascii -z input=/home/teste fs=tab skip=1
and nothing happens.
Is the command correct?

Thanks

What do you mean by "Nothing happens"?

Without an output=map_name it gives an error, and without z=3 it says
"ERROR: Please specify z column."

So try:

GRASS 6.1> v.in.ascii -z z=3 input=/home/teste fs=tab skip=1 output=test
