This study uses genetic algorithms to formulate and develop land use plans. The restrictions to be imposed and the variables to be optimized are selected based on current local and national legal rules and experts' criteria. Other considerations can easily be incorporated in this approach. Two optimization criteria are applied: land suitability and the shape-regularity of the resulting land use patches. We consider the existing plots as the minimum units for land use allocation. As the number of affected plots can be large, the algorithm execution time is potentially high. The work thus focuses on implementing and analyzing different parallel paradigms: multicore parallelism, cluster parallelism and the combination of both. Some tests were performed that show the suitability of genetic algorithms to land use planning problems.
Resumen: Este artículo describe el desarrollo del sistema de información del Banco de Tierras de Galicia, organismo gallego que actúa de intermediario entre propietarios y agricultores para fomentar el arrendamiento de tierras y evitar su abandono. Sus objetivos son realizar la gestión interna del Banco, difundirlo entre el público y facilitar distintos tipos de tramitaciones a través de Internet. El sistema, disponible en http://www.bantegal.com/sitegal, está formado por una aplicación web con componentes SIG que ofrecen una mayor y mejor información sobre las parcelas y su entorno. El desarrollo se apoya en el uso de software libre y en la utilización de estándares para el manejo de la información geográfica. El artículo detalla la arquitectura, componentes y funcionalidades del sistema y ofrece datos estadísticos de su utilización.
