This work is related to the area of Geographic Information Retrieval (GIR). In this work, a GIR system has been designed, developed and evaluated, applying different techniques of Natural Language Processing (NLP), several infor- mation retrieval engines and using external geographic knowledge resources. The developed system is modular, allowing the integration of other modules or knowl- edge resources. The main novelty of the system is to use an architecture based on creation of different subqueries from the original query, the use of three textual in- formation retrieval tools and different fusion techniques of document lists, achieving improvements in variability and coverage of the documents retrieved.
