Integrating GIS's and remote sensing image analysis systems by unifying knowledge representation schemes

The major barriers to the integration of remote sensing image analysis and geographical information system (GIS) technologies include the problems with data format, data accuracy, and system communication. This research explores a new path for achieving the integration. The three problems, which at first may seem to be independent of each other, are considered as different aspects of a problem with knowledge (information) representation and are tackled by unifying the systems on a common knowledge representation framework. Three new techniques-relational-linear quadtree, fuzzy representation method, and communication subschema-have been developed to provide such a framework.<
