Xrmap is an GPL'd user-friendly X program which can be used to generate
|
|
accurate images of small or bigger portions of the Earth. The main data
|
|
source is the CIA World Data Bank II.
|
|
The CIA_WDB2 consists of vector descriptions of coastlines and islands,
|
|
political boundaries, major and minor rivers, glaciers, lakes, canals,
|
|
reefs, etc. The accuracy of the data is at best 1" of arc, approximately
|
|
30 meters at the Equator -- in fact all recorded points are given by
|
|
integer coordinates representing seconds of arc.
