There is no readme for the map downlaoded application, as with MapThis! the GPL licence applies.
(from http://www.gnu.org/copyleft/gpl.html, and attached in LICENSE.TXT).

Keep in mind the disclainer from MapThis!, below, and also consider the terms for using data from the other sources.

The NASA Open Source license now also applies as access to NASA World Wind's servers is now possible.
(see http://worldwind.arc.nasa.gov/index.html for further information)
