With the proliferation of Location-Based Services (LBS) and the increasing amount of geographic data, many issues arise related to the integration of spatial data and their visualization. The thesis’ objective aims at tackling these challenges by integrating LBS offered by multi-providers in the context of touristic Points Of Interests (POI). In this document, a short state of the art of data integration and cartography are presented, followed by an example that describes issues and specificities related to LBS integration and finally a generic solution is proposed.
