Map Overlays

Some coastline and border outline overlays included with G.Projector are based on the Micro World Data Bank II (MWDB II) dataset, originally created by Fred Pospeschil and Antonio Rivera. We use the version dated 2011 that is available for download from Fred Pospeschil's MWDB II website.
