That's true, we haven't completed that. Our MRO, MSL and LRO work has cut into the hobby time I used to make the B&W mosaics, and the color mosaics are much more labor-intensive to make.
The sheer amount of data is amazing. Your 256 pixels/degree map is multiple gigabytes, but even then is only a fraction of the MOC resolution. I'm looking for a map from which to generate simulated HiRISE views, but 256 pixels/degree at the equator works out to 232 meters/pixel, compared to the HiRISE resolution of 0.30 meters/pixel. For the 1.14 degree FOV, the 256 ppd map at 300 km altitude affords about 26 pixels across, compared to 20,000 for HiRISE. Of course, I shudder to think of how many bytes a full MOC resolution map would entail, and the amount of work involved making it.
Phil: Thank for the links. I'll have to read up on that JPEG2000 format. I tried a couple of programs that are supposed to read that format but they both bombed out with a Windows unrecoverable application error when trying to read the images (over 200 MB JPEG2000). Maybe I need more than 512MB RAM!
