(in addition to lots of the things that other people have said) 1) That not everything that's already mapped is perfect. I started straightforwardly adding GPS tracks in a large area of blank space, but agonized for ages over moving a road that looked like it was in the wrong place (I didn't want to change something that I didn't understand why it seemed to be incorrect). 2) That it's always helpful to add a source tag. Initially I wrongly assumed that all data came from GPS tracks, not realising that quite a lot of features are traced from places such as Landsat, Yahoo, out of copyright maps etc. and that (related to the previous point) not all of those features are still present and correct. 3) That there are sometimes several different, equally correct and mutually incompatible ways of doing certain things. 4) That the wiki isn't always helpful and sometimes contradicts itself, and that "what people have used before to describe X" is usually a better guide (and that places like osmdoc.org exist). 5) That OSM has it's very own version of the "vi vs emacs" debate. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
