    Explanation
    The Digital Map Processor (DMP) component of the F-15E digital map system (DMS) uses present position information and scale select information to determine which map to display. The DMP processes the data and selects the appropriate map based on the aircraft's current position and the desired scale. It then displays the selected map on the aircraft's display system, providing the pilot with accurate and up-to-date navigation information. The Mission Cartridge (MC) and Theater Cartridge (TC) are not directly involved in determining which map to display, and the Advanced Display Core Processor (ADCP) is responsible for processing and displaying sensor video data, not map information.
