SIGHabitar - Business Intelligence Based Approach for the Development of Land Information Systems: The Multipurpose Technical Cadastre of Ouro Preto, Brazil

This paper evaluates the use of Business Intelligence(BI)technologies as a viable approach to the efficient engineering, update and evolution of Multipurpose Technical Cadastres (MTC) in the context of Land Information Systems (LIS). For this, the MTC of a small Brazilian city named Ouro Preto, located in the Minas Gerais state, has been built as a spatiotemporal data warehouse and BI tools have been used to developing the LIS. The system architecture, conceptual data model and tools are presented. Evaluation experiments have shown that, in two months, 92% of 3,037 realties registered in the study area have been correctly georeferenced and associated to legated information systems. We estimate that fifty percent of project investments will be recovered in the first year in which the LIS will be used to collect taxes and
