Abstract. Data Warehouse (DW) is a dimensional database for providing decision support by means of on-line analytical processing (OLAP) techniques. Another technology also used to provide decision support is Geographical Information System (GIS). Much research aims at integrating these technologies, but there are still some open questions, particularly regarding the design of a geographical dimensional data schema. This paper discusses some related work and proposes GeoDWFrame that is a framework based on the star schema and has been specified as guidance for designing geographical dimensional schemas. Some experimental results are also given.
