Adding the Third Dimension to Digital Mapping

Abstract

The Digital Mapping, Charting & Geodesy Analysis Program (DMAP) at the Naval Research Laboratory has been developing the distribution of geographic data over the Web through its Geospatial Information Database. While this work has primarily included digital mapping information from a variety of formats, DMAP has also been working on 3D synthetic environment data delivery. This chapter describes DMAP's work to provide a three-dimensional representation of geographic data. We provide an overview of the data structures used to reconstruct 3D synthetic environments and to store full 3D topology. We also describe a prototype that supplements traditional 2D digital-mapping output with a 3D interactive synthetic environment.
