Thanks Paolo. I'll post any new material directly in the wiki. GMT is tough to
get into, it took me a while to become comfortable with it. I would
reccommend looking over lots of examples if you are interested in learning.

José,
I have been interested in implementing potential fields function in
GRASS since long,
but I don't have the necessary background (I mean, I don't know the
equations) or the coding skills.
However, I can help you test/debug.
Maybe that could be the starting point for me to learn

Hello. I can not use the number pi in r.mapcalc. I tried these ways:
r.mapcalc 'prueba = pi()'
r.mapcalc 'prueba = pi'
r.mapcalc 'prueba = PI()'
r.mapcalc 'prueba = PI'
With the following results:
Syntax error
Is this normal? Is IP defined within GRASS / r.mapcalc?
Thanks for your help.

r.mapcalc doesn't have a definition for pi; you'll need to enter a
literal value.
Thanks Glynn. This sounds like a weak point for me.
I need to introduce Pi several times. Not for converting degrees to
radians. It is another class of applications.

Is it possible to define variables?
2008/8/23 Glynn Clements [EMAIL PROTECTED]:
Yes; an assignment anywhere other than at the top level will define a
variable rather than an output map. You can either place the
assignment at the point that you
