"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.

I reprojected the VIRTIS heatmap to a more usable Lat Long format. I hope it might help trying to determine where to put north and stuff in my model to be in the same coordinate space as ESA. The projection choosen has considerable overlaps where the neck and the head share the same map coordinates. That is a bit easier to see when draped over the shape model. So I rendered a little movie: http://mattias.malmer.nu/2014/10/virtis-heatmap/ |
