Monitoring urban development consolidation for regional management on water supply using remote sensing techniques

Abstract

This work's frame is the assurance of water availability/demand balance in the Community of Madrid linked to the urban growth. The paper presents the development of an operative methodology to define and create a cartographic database in the Community of Madrid. based on SPOT5 satellite imagery and its periodical updates with a further usage of QuickBird images for its validation. This database reflects the evolution of urbanized areas as a result of the Urban Development Plannings' consolidation in all municipalities, as well as the state and evolution of green urban areas. The resultant cartographic database has been integrated in the Canal de Isabel II's Geographical Information System and is intended to be the reference information for the development and updating of the strategic infrastructure plans that should anticipate to future water demands caused by urban expansion in the Community of Madrid.
