Geographic data integration to support Web GIS development.
Résumé
Although research in data integration has become one of the main issues in [6], geographic data integration is still a laborious and complicated problem, even for specialists. Geographic data is of great importance as it describes the surface of the Earth and its interactions with mankind. It has its own specific issues as it can be spatially indexed. Ex- changing data in real-time through the internet has changed Geographic Information System (GIS) paradigm from closed desktop applications to distributed ones. This research aims at investigating the problems surrounding geographic data integration in order to aid the development of optimized Web GIS.
