THEIA OSO RASTER
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 classification raster is a single raster covering the whole French metropolitan territory. It has a spatial resolution of 10 m. It results from the processing of the complete Sentinel-2 time series of the reference year using the iota² processing chain. A Random Forest classification model is calibrated using a training dataset derived from a combination of several national and international vector data sources (BD TOPO IGN, Corine Land Cover, Urban Atlas, Référentiel Parcellaire Graphique, etc.).
