Abstract
Geospatial information systems (GIS) are a relatively new technology. The key GIS technology strengths are its capabilities to store attributes of various spatial features, provide spatial-analysis functionality and offer multiple-perspective, two-dimensional (2D) and three-dimensional (3D) visualizations. This report presents an overview of the basic concepts of GIS and spatial databases, provides an analytical usability evaluation and critically analyses different spatial-database applications for different fields, with special emphasis on defence-related applications. We provide a comprehensive spatial-database evaluation methodology. Basic and advanced functions for GIS operations are analysed, with a focus on selected major GIS products and selected common database systems. Optimal system-requirement recommendations for spatial-database design are provided, with particular attention paid to the needs of the Advanced Deployable Day and Night Simulation (ADDNS) project. This report provides a detailed overview of spatial-database technologies to assist decision-makers with selecting the best system for a particular task.
