Well I'm sure you are aware of this, but there is a lot of very high res ( ~a few meters) Mars imagery available from MOC . I've had it in my head for a while now to try to put the all the available images into a network link, but I suppose that is easier said than done.

In any case, I do have an old set of MOC 'pic of the day' overlays at this post that I would like to use with your overlays. Unfortunately, they seem to have too low of a draw order to work nicely.
