Patent ID: 7769246

Claim:
A method for projecting and fusing multiple map images in an object oriented computer system onboard a helicopter, said method comprising: connecting a first map data object to a first map data source by invoking a map data connection process of the first map data object and providing a first map data source identifier; connecting a second map data object to a second map data source by invoking a map data connection process of the second map data object and providing a second map data source identifier; connecting a first map image object to the first map data object by invoking a 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 onboard the helicopter from the first map image object and the second map image object by invoking a map rendering process of each map image object and fusing the images together into the combined map image.
