The “Irrigation” Scientific Expertise Centre (SEC) brings together teams from Cesbio that develop high spatial resolution maps of irrigated / un-irrigated surfaces intended for regional chambers of agriculture, water supply agencies and watershed managers.
The product resulting from the Irrigated surfaces SEC is updated with an annual or biannual frequency. It has a decametric scale (between 10m and 20m) and covers all of France. Other sites may be taken into consideration on a case-by-case basis.
The data used are level 2A (or 3A) products from Sentinel 2, Sentinel 1 products and Landsat 8 data.
