Abstract :
An overview of geographic information systems (GISs) is given, covering data collection, applications, organization, and data models. Recent trends in map data processing are examined, namely, automatic name placement, map generalization, an automatic digitizer and expert system for land-use analysis, a map oriented system for urban planning, and a knowledge-based GIS. Techniques for extracting information from paper-based images are discussed, and some experimental results are given.<>
