Spatial Information Retrieval from Images using Ontologies and Semantic Maps

Abstract. Cameras provide integrated GPS technology which makes them a powerful sensor for geographical context related images. They allow wire-less connection to computers and the images can be automatically trans-ferred to a PC or can be integrated into a GIS system. In this paper we pro-pose an approach for spatial information retrieval from images using the concept of ontologies and semantic maps. The term of ontology is used in our case to describe spatial domain knowledge to enhance the search capa-bility and image annotation. The objects are represented by their location in semantic maps. We describe a developed prototype system with a database design for ontologies and semantic maps. We demonstrate the automatic image annotation and the visualization of the spatial queries. The system is oriented to the area of culture and tourism and provides a user friendly in-terface
