This paper describes and analyzes the results of our experiments in Geographical Information Retrieval (GIR) in the context of our participation in the CLEF 2007 GeoCLEF Monolingual English task. Our system uses Linguistic and Geographical Analysis to process topics and document collections. Geographical Document Retrieval is performed with Terrier and Geographical Knowledge Bases. Our experime...

Introduction Since its origin in the late 1980’s, the development of geographical information science and of geographical information systems (GIS), the toolset enabling to conduct this type of research, has now reached the necessary maturity to be considered a main stream application: GIS evolved from the status of ‘a promising tool’ to the status of ‘a tool achieving its promises’. To maintai...

The contribution presents an application of information visualization techniques in emergency medical services process analysis. We used a novel combination of simulation approach and geographical information system technologies to model and present large volumes of different kinds of information. The suggested methodology was used to evaluate system readiness for a major incident and the capab...

Developing a three-dimensional (3D) data model for Geographic Information Systems (GIS) is an essential and complex issue. 3D modelling in GIS is becoming ever more important for the development of cyber cities and digital earth, which have recently become feasible. A competent 3D model forms an efficient foundation for 3D visualization, query and spatial analysis. As a development of the exist...
