I don't mean you! But I encounter so many scientists who use maps all the time and don't understand them at all... Some terrible things are done in the name of cartography, even in the best journals. Perhaps the most common is referring to any cylindrical projection as Mercator.

Some terrible things are done in the name of cartography Would this be the cynical projection? One of the things I truly love about this forum (among many others) is how much I learn and how much threads like this inspire me to educate myself even more. I stole my one of my wife's GIS manuals for a little light night reading and what do you know, it's online as well: ESRI's Understanding Map Projections (2 MB PDF file) Beginner level, but I found it helpful.... I trust that the system works for Mars as well as Earth, though Eros, Itokawa et al might require different coordinate systems? Phil? This page has a good set of references for the cartographically challenged: Harvard GIS Resources And of course, what enthusiast autodidact post would be complete without mentioning the golden oldies: Remote Sensing Tutorial and JPL's Basics of Spaceflight -------------------- Lyford Rome

All this is well and good, Phil, but let me ask you a more sophisticated question. When you get a map out, whether it be cylindrical, mercator, or whatever, can you fold it back up properly?
