Xrmap is a program running under X that can interactively display portions of the Earth, using the huge CIA world vector map. It is based on an earlier console utility 'rmap'. It features political boundaries, major and minor rivers, glaciers, lakes, canals, etc. The map remains accurate under a very large zoom factor, which can possibly exceed 100. Spherical, rectangular, Mercator and Miller projections are implemented, and all features can be interactively set from the GUI.
