NORDA MC and G Map Data Formatting Facility: Development of a Digital Map Data Base.

摘要

Hardware and software systems have been developed at the Naval Ocean Research and Development Activity (NORDA) to provide digital mapping, charting, and geodesy (MC&G) data bases for Digital Moving Map Systems installed on naval aircraft. The computer system developed at NORDA is known as the Map Data Formatting Facility (MDFF). The MDFF transforms digital map data bases, distributed by the Defense Mapping Agency (DMA), into a form suitable for actual field use by the AV-8B, F/A-18, V-22, and A-12 naval aircraft and Tactical Aircraft Mission Planning Systems. These data bases include DMA's Equal Acr-Second Raster Chart Digitized Raster Graphic Data, Digital Terrain Elevation Data, and Digital Feature Analysis Data. In addition to describing the hardware and software components of the MDFF, this report gives an overview of current and proposed MC&G research projects being investigated in conjunction with the MDFF work. This research is primarily intended to improve the digital map display in the cockpit and to investigate new methods of compressing digital image data. Keywords: Cartography. (kr)
