I have been working with GIS and remote sensing in an university and professional environment some ten years ago (ArcInfo etc), so I have some experience even though somewhat outdated
Right now I am looking for an GIS application for a small farming project and I found GRASS and QGIS projects which sound both very interesting. However I do not really get the difference between the two programmes. Which one do I use best for simple thematic maps with different layers?
Thank you very much in advance.
