" Marble features a lot of historic maps from the age of discoveries, such as the Schagen map, see: World Map Schagen 1689 as an example.
are a possible source for more maps. Don't forget to check license and whether Marble includes such a map already. You can also create a historical map of Mars or the Moon if you find such data.
We've created a step-by-step-tutorial that you can follow to create these kinds of maps:
In order to prepare the map for use in Marble it needs to be morphed/reprojected. Once the map has been morphed you need to retouch the map using Gimp, Krita or Photoshop. This requires good skills on how to touch up graphics using e.g. the clone tool. The new map needs to have a legend included (like the other historical maps - you can use the existing ones as a template).
Expected results: A new historical map ready for upload to the GHNS server.
Prerequisites: Knowledge of editing xml files, Advanced knowledge of Krita, Gimp or Photoshop for touching up the morphed image and for creation of the map key."
