Exploitation of high resolution satellite data is an essential part for many research works associated with the understanding of physical phenomena describing our environment: the ocean and in particular the coastal zones where the phenomena are more complex due to the land/sea interactions, the land media at a regional scale and the urban zones where the interactions between countryside and cities are in constant evolution. The synergy with other data sources (other active sensors, passive sensors) allows to complement the processing methods and co-registered time/space access to data constitute a fundamental axis for the development of remote sensing technologies. The availability of an extremely large amount of data, optical as well as radar, for a large scientific community will eventually increase our knowledge in these phenomena and will allow us to bring some advances in the climate change consequences. Scientists will work for a better planning of the socio-economical developments at the regional scale, preventing natural hazards and possibly in the framework of renewable energy source implementations. This approach will have to be a model for the other Regions, European first, but as well for country under development – more specifically Africa – for global outreach through research work dissemination.
Several research teams from Telecom Bretagne, Ifremer, Université de Rennes 1, CNRS, Université de Rennes 2, Université de Bretagne Occidentale, Inria and Agrocampus-Ouest are the founding partners of the GIS BreTel. One of the goals of the GIS BreTel is to become the French and European leader in the domain of research and academic programs linked to the exploitation of high resolution satellite data for a better knowledge of the environment and an increase in security. The GIS was created with teams from the Brittany region, but one of its first goals is to bring the developments into a European context. Indeed the Brittany region is part of the European initiative NEREUS (« Network of European Regions Using Space technologies»).
The aim of the collaborative project GIS BreTel is therefore to reinforce the team links, federate collaborations between these teams and accelerate the shaping of a cluster focused upon a central theme – high resolution Remote Sensing – based on a large range of applications (oceans, coastal zones, land and urban zones) and build on information processing methods. A major asset is in the possibility to easily access data, not only for immediate actions but, as well, for long data series, for data acquired under very different conditions (geophysical – weather, wind, etc.- or system - resolution, polarization, etc.) but on the same zone. This possibility is highly linked with the VIGISAT station due to the associated services such as archiving, catalogs and processing. Furthermore, access to the data at several processing levels is fundamental for many applications as some part of the information is hidden in the final product.
