Abstract:

This report summarizes the studies, prototype development, and design decisions undertaken in the development of the Defense Mapping Agencys Vector Product Format VPF Military Standard and the new topologically structured global geo-spatial database, the Digital Chart of the World. The VPF is a generic, machine-independent format for Geographic Information System GIS data designed for use by diverse software systems. This format will be used by DMA for the provision of all future geo-spatial vector information products. The DCW is a comprehensive 11,000,000 scale vector basemap of the world. It consists of cartographic, attribute, and textual data stored on compact disc read only memory CD-ROM utilizing the VPF. The report covers the objectives, study methodology, and conclusions for each phase of the development effort. It covers design and prototyping, special studies, standards development, VPFVIEW software development, DCW database production, quality assurance, and other VPF product development
