Mars -
I and some others on the list come from the Arc world. I am always happy to
help share what cross-over techniques I have learned. After several years,
there are few to no things I cant do with open source GIS now
(QGIS/GRASS/GDAL/OGR), which I can do with Arc. The reverse is not true,
where there are things i can do in GRASS that I cant do in Arc (Simulations
come to mind, and true 3D modeling).
When you hit the daunting and challenging problems feel free to drop me
(and/or the list) a line. Someone can likely help walk you through it.
The best way to transition from arc to grass/qgis is to take it one task at
a time. decide on a task that needs completed, and work your way through
the resolution, and make good reference notes. A bit of mindset change will
need to occur, but I have found it to be for the best! GRASS/QGIS/OGR/GDAL
have restored the reason I got into GIS in the first place. Its fun! =D
