THE STUDY OF RELEVANT TECHNIQUES FOR INTELLIGENT INTEGRATION OF GIS AND RS

摘要

In recent years remote sensing (RS), geographic information systems (GIS) and global positioning systems (GPS), have been three main technologies for spatial information acquisition, spatial data storage management, spatial data updating, spatial analysis and applications. However, the integration of the three technologies is an important issue and a big challenge to the geo-information community. This paper addresses three technical aspects relevant for intelligent integration of RS with GIS: (1) possible database structures for integration, (2) application possibilities of the rough set theory in spatial data mining, (3) an approach of image clustering based on mathematical morphology in remote sensing.
