Re: Geophysics functions [was Re: [GRASS-user] use pi number]
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 something about it. Pointers to interesting sites/books/papers would be nice. =D At my current job I have access to plenty of datasets and experts, so we could use (borrow) further help =] José wrote: Yeah! I am studing for surveyor. At this moment, I am trying to finish a course of geophysics, one of the last courses, focusing on the use of GRASS and other free programs (I can send a copy of the presentations to you and all interested persons). I'm using GRASS at very low level, but I wish to get more deeply into GRASS. I am thinking about doing my final work in gerophysics (and free software of course). Therefore, interesting times very soon. as always, feel free to add any tips tricks relating to your research field to the wiki site: http://grass.osgeo.org/wiki/Applications Hamish ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
