OSO VECTOR
Main characteristics of the OSO Land Cover product : Production of national maps (mainland France). Nomenclature with 17 classes (2016, 2017) and 23 classes since 2018, spatial resolution between 10 m (raster) and 20 m (vector), annual update frequency. Input data : multi-temporal optical image series with high spatial resolution (Sentinel-2). The Vector format is a product with a minimum collection unit of 0.1 ha derived from the 20 m raster with a procedure of regularization and a simplification of the polygons obtained. In order to preserve as much information as possible from the raster product, each polygon is characterized by a set of attributes: - The majority class, with the same nomenclature of the raster product. - The average number of cloud-free images used for classification and the standard deviation. These attributes are named validmean and validstd. - The confidence of the majority class obtained from the Random Forest classifier (value between 0 and 100). - The percentage of the area covered by each class of the classification. This percentage is calculated on the 10m raster, even if the simplified polygons are derived from the 20m raster. - The area of the polygon. - The product is clipped according to the administrative boundaries of the departments and stored in a zip archive containing the 4 files that make up the “ESRI Shapefile” format.
