I have a friend on Labrador's North Coast who is doing (and has done) avalanche research. He is inquiring about Apple computers and research software. Number crunching, graphs, and GPS/map overlays is what he has on his agenda. I will see what he can get in the Apple line for $2000 max., but I am unfamiliar with what type of programs are out there for such research. Does anyone have any direction for me on this, and for my friend?
