Cameras can be very powerful sensors, enabling new user interaction metaphors and functionalities. They are not independent devices anymore and they can interoperate with external resources and services like user personal libraries, GIS systems, semantic GIS applications, semantic RFIDs, digital libraries, etc. In this paper, we present a Framework for the management of Semantic image information related to geospatial context and a system that has been built based on this Framework. Digital picture contents in the digital library can be interrelated with, and understood based on, contextual semantic geospatial information in the form of ontologies that the system manages. We describe the integrated camera system, the calculation and visualization of the contextual parameters, and the management of the semantics of the spatial objects. Finally, we present the implementation of SPIM, a picture management system that exploits spatial semantic contextual knowledge, its retrieval functionality and the visual user interfaces.

Keywords: context, ontology, semantic, spatial
