Aligns maplets to the current shape model and will provide slight changes to the shape (stored in MAPFILES).

Lithos is the key for SPC. It works on a single landmark, which defined the associated maplet. This landmark must be created (i.e. fully defined) and all the images it includes must be shifted so that everything is aligned. Once those are done, you can calculate the topography which includes identifying other maps that overlap, creating a template, and then solving the whole system.

The output from make_script(P) is used as input to Lithos and LithosP for batch processing. The mark_script program will create a script for each landmark that you will process, which is taken as input (e.g. lithos < LAND01.IIN > LAND01.OOT)

The MAIN MENU can be seen from within LITHOS by type "?" into the user prompt. The following list will be displayed.
