Abstract

The SATURN project (SATellite applications for Urban Mobility; Id SI2.680449 Agreement Number 632671) funded by the European Commission allowed the CEREMA to develop a demonstrator based on satellite imagery VHRS Pleiades (Very High Spatial Resolution) to deal with of urban challenges.

The project took place over a period of 18 months in 2014 and 2015. It is now complete and has produced a series of indicators for planners in charge of urban development.

Using data from the Urban Atlas enable to export the method to all European cities covered by the Copernicus territory service: the objective of Cerema is to get a reproducible product in other territories and ultimately to compare the different European cities. Use of the Urban Atlas data allows positioning this demonstrator as a downstream Copernicus cores services. Through its work in the framework of SATURN, the Cerema shows the added value provided by the imaging Pleiades VHRS. The mobilization in parallel with its double expertise in both space technologies and urban public policy, has helped to design relevant products. Several approaches can be considered to complete the Urban Atlas, or even possibly change the production method. A first axis is to complete the nomenclature with new attribute information (built surface rate, habitable floor area, high vegetation rate, low vegetation and soil sealing rate). The SATURN project is based on the geometry of the Urban Atlas without distinction and distributes the information from the classification as an indicator in each polygon.
