Abstract
Spatial Information revision and updating is the main concern and production effort of maintaining the ever-growing GIS systems and spatial Databases. Developing easily effected automatic updating methods of spatial information becomes the key to the successful maintenance of the large GIS data bases established by many mapping agencies all over the world. The paper presents the third phase in a three-year research effort for the development of automatic capabilities for updating the Israeli National Spatial Database. This ongoing research in funded by the Survey of Israel within the framework of maintaining the Israeli National GIS. Discussed are the experiments and the evaluation steps to define an efficient method for Change Identification and Feature Extraction. Presented are the GIS-Driven change identification and the texture classification methods.
