The Compressed Aeronautical Chart Database: Support of Naval Aircraft's Digital Moving Map Systems
Abstract
There is a recent movement toward the electronic display of aeronautical charts for mission planning and navigation in military aircraft. With the installation of the Digital Moving Map System (DMS) in the AV-8B harrier, the U.S. Navy has taken the first step toward the widespread use of electronic navigational charts in its aircraft. In order to maximize the benefits from these systems, a new map image database has been specifically designed to meet the requirements of the DMS. The Naval Oceanographic and Atmospheric Research Laboratory (NOARL) is creating a compressed aeronautical chart database by compressing and transforming scanned chart data into a format that is compatible with the aircraft DMS. Image compression techniques have been chosen to allow rapid decompression and display while maximizing image quality. Production of the database, which will be distributed by the Defense Mapping Agency (DMA) on Compact Disk - Read Only Memory (CDROM), began at NOARL in February of this year.
