Reliability scores for the grassland map (Copernicus)
What it measures. A companion quality layer indicating how confident the matching grassland map is at each location, rather than mapping grassland itself.
How it's made. Produced yearly from 2017 onward by the EU's Copernicus Land Monitoring Service as a 10-metre grid across Europe's 38 countries, including French overseas territories.
How & where you'd use it. A technical support file letting analysts gauge how much to trust the grassland classification at any given spot.

Official description
The High Resolution Layer Grassland Confidence Layer (GRACL) is a quality support raster. This dataset is provided annually starting in 2017 in 10 meter rasters (fully conformant with the EEA reference grid) in 100 x 100 km tiles covering the EEA38 countries. High Resolution Layer Grasslands product is part of the European Union's Copernicus Land Monitoring Service. This dataset includes data from the French Overseas Territories (DOMs).
