The current aim of the project is to build a map server dedicated to providing map layers for the surfaces of known astral bodies, such as the Sun, the planets and the various non-man-made satellites.

The data the project depends on should be of an open nature, whether that is public domain, creative commons or an alternative license that allows use in a non-commercial context.

The current design assumption of the project is to provide a collection of JSON files that indicate the location of the source map data, along suitable metadata and then have a script that fetches the source map data and then via a script prepare the content for distribution.

This is still very much a work in progress and not ready for deployment, though if you want to take a peek at the work in progress, you can take a look at the dev server, which should be treated as highly unstable and more of a experimental lab.
