Abstract
A method for storage and retrieval of digital map data representative of a tessellated sphere including five zones. Firstly, the number of tessellations for each zone is defined. Secondly, the range of each zone is defined. Next, the radius of the sphere is defined. A sphereical data base is then created by warping the digital map data into the spherical data base by latitude and longitude. Finally, data from the spherical data base is retrieved and the data may be displayed on a cathode ray tube (CRT) display or a flat panel liquid crystal display.
