Abstract

Since 1994 the Digital Mapping, Charting and Geodesy Analysis Program at the Naval Research Laboratory has been developing an object-oriented spatial and temporal database, the Geographic Information Database (GIDB™). Recently, we have expanded our research in the spatial database area to include three-dimensional synthetic environment (3D SE) data. This work has focused on investigating an extension to the National Imagery and Mapping Agency's (NIMA's) current Vector Product Format (VPF) known as VPF+. This paper overviews the GIDB and describes the data structures of VPF+ and a prototyped 3D synthetic environment using VPF+. The latter was designed as a 3D Geographic Information System (3D-GIS) that would assist the U.S. Marine Corps with mission preparation and also provide onsite awareness in urban areas.
