CNES Land Cover Map

Short description

The CNES Land Cover Map (Occupation des Sols, OSO) produces land classification for Metropolitan France at 10 m spatial resolution based on Sentinel-2 L2A data within the Theia Land Cover CES framework. Maps for 2020, 2019, and 2018 use a 23-categories nomenclature. For earlier maps in 2017 and 2016, a fully compatible 17-classes nomenclature is employed.

Band information

The CNES Land Cover product contains 3 bands. The OCS band contains main classification data with class values ranging from 1 to 23. The Land Cover nomenclature and colouring scheme is shown below.The other 2 bands are OCS_Confidence and OCS_Validity. The OCS_Confidence band provides the information on the classifier confidence with values ranging from 1 to 100. The OCS_Validity band indicates the number of cloudless images.
