GMES Urban Services (GUS) is a project from the European Space Agency to consolidate a product portfolio, based on the combination of satellite images and in-site data, that enables the municipalities, regional, national and European authorities to address efficiently the urban strategic planning with a focus on environmental issues.

The project is being developed by a consortium of 10 European partners leadered by Indra. Within the portfolio we include high resolution land use maps, change detection maps, hot spot identification of new constructions, 3D city modelling, thermography, noise observatory maps, risk maps, etc.

GMES is a joint initiative of the European Space Agency and the EC. Many programmes (EC, ESA, others) will eventually contribute to GMES. In November 2001 the ESA Ministerial Council approved a new 5-year ESA programme dedicated to GMES, called the Earthwatch GMES Services Element (GSE for short). This is the very first programme dedicated to GMES. GSE will deliver policy-relevant services to end-users, primarily (but not exclusively) from Earth Observation sources. GSE is a key element of GMES, because it will enable end-users to become key players in the move from present generation Earth Observation satellites to future European systems that will deliver vital information on global environment and security.
