Abstract: An mechanism for range estimation mapping that includes creation of a world map on an azimuth/elevation (AZ/EL) grid, relation of the grid to an earth-fixed north, east, and down (NED) coordinate system through an address table, and association of each pixel in each frame, by a programmable device, with an entry from the address table in order to determine a range is discussed. The associations may be repeated for each frame while an updated world map and address table are generated. When an updated address table is complete, the process may begin anew using the updated data.
