Simulated resolution of the various cameras on orbit at Mars right now - all the way from 100000 to 30 cm smile.gif

At least - once the FTP is back up and running. Grrrr..

I just hope Google Maps don't try and send me to jail for using their pictures ohmy.gif

Very useful, but a couple of observations: first, maximum THEMIS VIS resolution is 18m, not 12m (probably close enough). More importantly, I would say that this overestimates the true image quality at all resolutions. The highest resolution images in Google Maps are from scanned air photos, which probably have roughly 3x the sharpness of satellite images at equivalent sampling.

I usually advise that people run a blur filter of about 1.5-2 pixel radius for these sorts of simulations. Of course, it depends on the point you're trying to make.
