Patent ID: 7492965

Claim:
A method for projecting and fusing multiple map images in an object oriented computer system on an aircraft, said method comprising the steps of: creating a first map data object, wherein the first map data object comprises a map data connection process and a map data retrieval process; creating a second map data object, wherein the second map data object comprises a map data connection process and a map data retrieval process; creating a first map image object, wherein the first map image object comprises a map data selection process and a map image rendering process; creating a second map image object, wherein the second 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 first map data object to a first map data source by invoking the map data connection process of the first map data object and providing a first map data source identifier; connecting the second map data object to a second map data source by invoking the map data connection process of the second map data object and providing a second map data source identifier; connecting the first map image object to the first map data object by invoking the map data selection process of the first map image object and providing an identifier corresponding to the first map data object, and connecting the first map image object to the map projection object; connecting the second map image object to the second map data object by invoking the map data selection process of the second map image object and providing an identifier corresponding to the second map data object, and connecting the second map image object to the map projection object; connecting a map image of the second map image object to a map image of the first map image object; and creating a combined map image on an aircraft from the first map image object and the second map image object by invoking the map rendering process of each map image object and projecting a map image from each of the first map image object and the second map image object by invoking the map projection process of the map projection object by fusing the images together into the combined map image.
