Since the development of Geographic Information Systems (GIS) and the increasing popularity of mobile devices, many standardization bodies such as OGC (Open Geospatial Consortium) had proposed the implementation of Location Based Services (LBS) applications. Furthermore, map service providers started to use the correspondent devices for visualizing geo-graphic data essentially based on the users' location, his contextual infor-mation and his profile. However, many geographic databases (GDBs) could offer slightly different data/metadata for the same requested service. Advanced LBS have to improve interoperability among them. In this paper, we had elaborated many reasoning algorithms and build/match extended geo-ontology framework for the integration of homologous objects on mobile devices. Our approach is illustrated by a tourism LBS case study and could be applied for any geographic domain where posi-tion, place name, semantic details and visual aspects' (icon, texture, color, etc.) ambiguities will be integrated automatically through our platform.
