Abstract:
1. A method for creating connectivity between map data and a map image in an object oriented computer system, said method comprising the steps of: creating a map data object, wherein the map data object comprises a map data connection process and a map data retrieval process; creating a map image object, wherein the map image object comprises a map data selection process and a map image rendering process; creating a map projection object, wherein the map projection object comprises a map projection process; connecting the map data object to a map data source by invoking the map data connection process of the map data object and providing a map data source identifier; connecting the map image object to the map data object by invoking the map data selection process of the map image object and providing an identifier corresponding to the map data object; creating a map image by invoking the map image rendering process of the map image object; and outputting the map image.
