Greetings<div><br></div><div>I'm preparing a small GIS tool to High School students to do some image processing, image vizualization etc and I'm thinking of using GRASS since is free and pretty much do what I need. But I realized that 6.4, 6.5 and 7 have different characteristics, functionalities. What I need to know is if there is any document that compares and assesses these 3 versions in order to characterizes each one. For instance GRASS6.5 is able to have dynamic wxpython scripts (e.g. v.krige) that is an interesting funcionality.</div>
