Abstract

The design concepts and languages of a geographic information system ATLAS (Administration and Total Landuse Analysis Support system) are proposed. The database structure is designed based on the geographic information structure concepts which contain semantic structure, topological structure and location structure. For a flexible user interface, the system provides two languages) IGL (Interactive Geographic Language) and GDDL (Geographic Data Definition Language), whose functions are designed based on the geographic information structure concepts. IGL is an interactive end user language, which facilitates information retrieval under geographic and/or statistic conditions and thematic map production. GDDL is a language for a system manager who constructs and maintains the database.
