Re: [GRASS-user] Getting Started with GRASS Python Scripts

Hello Paolo, Yes, my initial thought was to just use GRASS via SEXTANTE. I tired to do this, but did not have any luck. I posted previously on 14/5/2013 to qgis-users with the subject "How to run SEXTANTE algorithms outside of QGIS Python console?" but did not get a solution to the problem I encou

Dear all, I need a suggestion. I have 180 point dislocated in europe, at which are a value (gps tropospheric delay) that vary in time (every 2 hours) for several years. I want to interpolate between such points to create a raster map for each temporal istance (one every 2 hours), and then look

[GRASS-user] r.example

Hi! I'm a newbie to GRASS and would like to do some C programming with its modules. I'm having some troubles putting to work just a simple raster example (r.example)! I'm on a Debian squeeze machine and installed Quantum GIS with the GRASS plug-in. Nevertheless I installed GRASS (version 6.4
