Local authorities´ obligations about monitoring of urban and green areas and contribution of very high resolution images: Examples in France and Belgium

Local authorities adapt regularly their land policy and land management tools, in order to control urban evolution or to integrate environment protection measures for example. To achieve the diagnostic of the situation and to follow up the effectiveness of the policies, an inventory of the current landuse/cover at local to regional scale is needed for both urban changes and green network management. Remote sensing methods using VHR imagery can help authorities to achieve this integrated multi-scale landuse coverage.
