A DISCUSSION ON SOME TRENDS OF GEOGRAPHIC INFORMATION SYSTEMS

:Based on the progress of geographic information systems (GIS) in different countries, thedefinition and basic components of a GIS were involved, and five trends relating to the deve-lopment of GIS were discussed. These trends are as follows:1. The GIS has become an important component of a being perfected technical systemapplied to geography;2. To perform various types of spatial analysis represents a major aim in applicationsand research of GIS;3. The most important technical topic within the field of GIS concerns the spatial datastructures;4. The integration of approaches and procedures within a single system is becoming in-creasingly evident;5. A great attention has been paid to the research on the standardization and artificiai in-telligence techniques.
