Reliability scores for the grassland-change map (Copernicus)
What it measures. A companion quality layer describing how trustworthy each pixel is in the matching map of grassland gains and losses, rather than the grassland information itself.
How it's made. Refreshed every three years by the EU's Copernicus Land Monitoring Service as a 20-metre grid across Europe's 38 countries, including French overseas territories.
How & where you'd use it. A technical support file that helps analysts decide which parts of the grassland-change map are dependable before using them.

Official description
The High Resolution Layer Grassland Change Confidence Layer (GRACCL) is a quality support raster product. This dataset is provided in 20 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).
