Rule-based system for updating spatial data-base

Research output: Contribution to journalConference articlepeer-review


Spatial Information revision and updating is the main concern and production effort of maintaining the ever-growing GIS systems and spatial data bases. 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 objective of this research was to develop a rule based system for updating a spatial database. Taken into consideration were rules, such as: (a) The radiometric and textural parameters; (b) The geometric parameters of the objects, such as area, perimeter, compactness, elongation, etc; and (c) The topological relationships between objects of the same type group and from different layers, as well. This paper presents the algorithms and rules which were implemented for updating the Israeli National GIS spatial database. Also, discussed are the experiments implemented over the Haifa region test site.
