SPATIAL DATA INTEGRATION USING ONTOLOGY-BASED APPROACH

S. Hasani, A. Sadeghi-Niaraki, M. Jelokhani-Niaraki
2015 The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
To solve this issue, we introduce an ontology-based method to provide sharing and integration capabilities for the existing databases.  ...  Last step is consisted of a platform based on service-oriented architecture, which allows integration of data. This is done by using the concept of ontology mapping.  ...  There are some other reasons such as complexity of the system maintenance and impossibility of using legacy applications.  ...
