[Geodata] Natural Earth public domain data

[Keith Jenkins]

FYI,

In December 2009, Natural Earth started offering "free vector and
raster map data at 1:10m, 1:50m, and 1:110m scales. This is a NACIS
and MapGiving co-branded product with assistance from the University
of Wisconsin-Madison cartography lab, Florida State University, and
others."
