This program integrates high-resolution shaded topographic imagery and several kinds of map information to provide a 3D view of earth. The vector map displays layers including political boundaries, coastlines, islands, lakes and lat/lon grids. There are also four types of point maps, including 267 countries and regions, more than 40,000 ranked cities, 15,000 islands and 1,700 historical earthquakes. You can rotate the globe, zoom in and out, and measure distances between any two points.
