"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.

well the landing site is near 190 long and just a bit north about 15 north
some pics in 3D of the area and a DEM ( using SFS) there is a zip of the mesh ( not 100% accurate to the comet ,just an approximation ) https://googledrive.com/host/0B6ZYAd08tZL-V...LandingSite.zip PhilaeLandingSite.zip │ ├── PhilaeLandingSite.mtl │ ├── PhilaeLandingSite.obj │ ├── Philae_s_primary_landing_site1.png │ ├── sfs_DEM.32bitFloat.tiff │ └── sfs_DEM.8bit.png the heightmap is from this image http://www.esa.int/spaceinimages/Images/20...ry_landing_site using Shape From Shade |
