Maps of the world (and Mars for good measure).
Far from complete, but the most complete map source I've ever seen.
About 18 GB of images.
Utterly stunning resource (if you're stunned by such things).

Note - I am uncertain about the copyright status of this material. They list
sources.

____________________________________________

Best starting point: Access to individual maps - each entry is a directory
of maps for an area or country and may be clicked on safely. Below this
level there may be individual maps or sub-directories to more localised
areas.

    Maps are mostly large files (several MB each, some MUCH larger) so click
carefully.

Map indexes
Note that these are downloadable files - typically several MB each and up to
10 MB.

Here is the home page which is NOT the most useful access point as it gives
you FTP links to whole area directories - often hundreds of MB at a time.
