Re: [GRASS-user] ITRF92 Not found.
Thank you! You are really great! This is going to be so much useful to Mexican people, You are very kind. How can I help, How can I include other definitions for Mexico like ITRF08? I remember that Grass has US states projection definitions in order to create sites, Is there a way that I can achieve the same? Thanks again for all your effort and kindness. Javier García Prieto.

[GRASS-user] v.mapcalc
Hi How are you? After solving thanks to Stefan and his r.slope.direction how to calculate the slope along the keyline, now I have to solve how to create parallels to the keyline. Nothing easier: see parallel! But I have to create many. In the graphical modeler I can't learn how to use the loop. Damn if I'm ignorant. But maybe v.mapcalc would also be very handy.
