It can be a rather additional specific reiteration with the Electronic Chart of the planet (DCW) which was created within the 80's and early 90's, and is therefore dated. However depending on your needs, VMap0 should still supply valid geometry for functions that do not alter considerably (like coastline and drainage) and offers a great starting point navigate to these guys for areas of the World the place vector info is tough to return by.
Level 1 (VMap1) is at a scale of one:250k, and about 1 / 4 of the entire world's coverage is in the public domain.
