    Abstract
    Describes a WWW based system which allows users to view, search and post geographically indexed information of the Earth. 2 geographic browsers have been developed: a 2D map browser capable of continuous scroll and zoom of an arbitrarily large sheet and a 3D flight-simulator browser capable of continuous flight around the Earth. On the server side, a geographical and geometrical server has been developed which contains large databases of images, elevations, lines, points and polygons stored in tiles structured into hierarchical pyramids or quadtrees. A metadata server has also been developed which contains URL pointers and geographical coordinates of various WWW documents, geographical information and geometrical models
