摘要

讨论了军用飞机任务规划和导航航海图电子显示的发展趋势。随着AV-8B“鹞”式战斗机上安装数字移动地图系统(DMS)，美国海军向在其飞机上广泛使用电子航海图迈出了第一步。为了使这些系统的效益最大化，专门设计了一个新的地图图像数据库来满足DMS的要求。美国海军海洋学实验室和大气研究实验室(NOARL)正在通过将扫描图数据压缩并转换为与飞机DMS兼容的格式，创建一个压缩的航空图数据库。图像压缩技术已被选择，允许快速解压和显示，同时最大限度地提高图像质量。

The compressed aeronautical chart database: support of naval aircraft's digital moving map systems

The trend trend toward the electronic display of aeronautical charts for mission planning and navigation in military aircraft is discussed. With the installation of the Digital Moving Map System (DMS) in the AV-8B Harrier, the US 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 Laboratory and Atmospheric Research Laboratory (NOARL) is creating a compressed aeronautical chart database by compressing and transforming scanner 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.<>
