DTIC ADA231465: Geographic Information Systems: A Primer

GIS offer a computer-based method for systematically recording, storing, retrieving, analyzing, and portraying geographically referenced information. New techniques for spatial analyses are also provided that range from multi-layer stacking and interpretation of georeferenced data to automatic construction of new coverages (digital maps) produced by intricate and analytical routines. Developmental trends currently under way indicate that merger of computer-assisted cartography (CAC), computer aided design and drafting (CADD), and GIS technologies is taking place under the umbrella of spatial data analysis and management. Segregation of the technologies is becoming less and less apparent, and the capabilities provided therein are becoming more and more interdependent. As a result, GIS is not currently unified in a well-defined disciplinary niche and suffers from a serious lack of definition of terminology, concepts, and standards. This report is intended to serve as a primer for middle and upper management personnel who may be considering applications of GIS hardware and software with intent to apply GIS technology in solution of local problems. Concepts are defined, and an attempt
