"A 2D map of C-G seems like a tough order; the projection math alone..." Don't worry! If you can put a grid on the surface (as we have seen already), you can warp that grid into any map projection you like. Mapping will be no huge problem - in fact I expect they have a rough one already (I've been playing with one myself). Phil -------------------- ... because the Solar System ain't gonna map itself.

thanks, Gerald, for your insights. I noticed you follow the Rosetta blog, too. Unless another Gerald is at work there! My own name (Peter Groeneweg) is a bit too difficult so on the ESA blogs I'm PeterG.
In my previous entry my use of the English language is perhaps "difficult" too, so let me say here what I really wanted to say: I feel privileged to be a member, a junior member to be more precise, of a forum that has experts like Phil in its ranks. No unmanned spaceflight subject seems too arcane for the forum! A further thought: is a cartography system the province of ESA, or does it need endorsement by the international organization(s)? One thing seems sure: after the initial spectacular success at 67P/C-G I expect more missions to follow and a sound cartography system seems most useful to have by then. |
