Tigris: Topolosically Integrated Geographic Information System
نویسنده
چکیده
A Geographic Information System (GIS) requires both interactive edit/query, and power-ful spatial analysis capabilities -for large volumes o-f geographic data. This spatial analysis requirement has led to the investigation o-f the mathematical -field o-f topology. The major problems o-f previous topological systems have been the construction o-f a logically consistent topological structure and the integration o-f structured spatial data with nonspatial attribute data. The TIGRIS system incorporates both types o-f data into a single, highly interactive data base using an object oriented system on Intergraph's stand alone workstations. This paper describes TIGRIS and its design.
