This paper presents the GeoSphereSearch engine for context-aware geographic queries on the Web. It facilitates the formulation of geographic queries and the visual presentation of discrete or aggregated query results in an intuitive manner. In contrast to other approaches it does not assign geographic footprints to documents, but considers context-aware geographic information on the fly, allowing a fine-grained query evaluation on the level of document fragments, not complete documents.
