Welcome to the Kalideos Littoral Web site !

After Kalideos Adam and Kalideos Isle-Reunion, Kalideos Littoral is the third of the reference remote sensing databases set up by CNES. This reference database concept results from CNES will to support research in remote sensing by collecting the largest possible amount of images from various sensors on a few selected sites and giving free access to the scientists who would like to include them in their basic or applied research activities.

The Kalideos Littoral database is more particularly aimed at researchers working on coastal areas, complex ecosystems at the crossroads of many themes (study of sea phenomena, town-and-country planning, environmental protection…). That is why the French scientific community concerned by coastal management issues has been widely asked for advice before selecting the test site to implement this database.

The selected site is the Arcachon basin, located on the French Atlantic coast. This high potential study area is especially interesting not only in terms of research for a better understanding of coastal ecosystems, but also of issues concerning town-and-country planning. It merges indeed very diverse topics, from dune erosion and displacement of shoreline to water quality, more particularly around aquaculture sites, through urban development and tourism pressure.

Thus, the Kalideos Littoral database first aims at promoting remote sensing towards researchers specialised in coastal areas, some of them still not using this technology, by offering them an opportunity to use satellite data customised to the issues specific to these areas in a simple and practical way.

The second objective is to provide scientific teams with preprocessed spatial data with a known geometric or radiometric quality level, which they will be able to interface directly with their models in order to develop new applications.

Finally, the third objective is to allow these teams to enhance themselves the database with their own information (maps, ground data, specific measurements, links towards specialised Web sites…) and the results derived from the analysis of images (value-added products, technical reports, scientific papers…)..
