An Initial Design of Extended Vector Product Format for Modeling and Simulation.

Abstract

The Digital Mapping, Charting, and Geodesy Analysis Program (DMAP) has been tasked with making the Defense Mapping Agency's (DMA) georelational Vector Product Format (VPF) more amenable to the Modeling and Simulation community. Under the direction of DMA's Terrain Modeling Program Office and the Defense Modeling and Simulation Office, DMAP has used requirements survey analyses and user feedback to devise a draft Extended VPF (EVPF), utilizing the design constraint of a relational database model. EVPF incorporates a new primitive structure for incorporating a Triangulated Irregular Network (TIN) as a means of representing three-dimensional surfaces. While VPF allows for the storage of three dimensions, this concept has traditionally been exploited primarily as elevation attributes of features. EVPF also stresses the use of attribute tables for storing rendering information. Using variable-length attribute fields, a current VPF capability not used to its fullest extent is also recommended for richer feature attribution.
