Europe's grasslands at coarse 100-metre resolution (Copernicus)

CLMS VLCC Grassland (GRA) Europe 100m yearly V1
biosphere ESA ESA Copernicus active
In plain English

What it measures. Shows the share of grassland within each 100-metre cell, covering managed, semi-natural, and naturally grassy areas, but excluding short-lived temporary grasslands.

How it's made. Produced yearly from 2017 onward by counting grassland pixels and storing their percentages, by the EU's Copernicus Land Monitoring Service across Europe's 38 countries, including French overseas territories.

How & where you'd use it. Good for continent-wide summaries and statistics on grassland extent where a broad overview is more useful than fine detail.

Official description

The High Resolution Layer Grassland (GRA) dataset provides binary status layer of grassland/non-grassland mask. This grassy and non-woody vegetation baseline product includes all kinds of grasslands: managed grassland, semi-natural grassland and natural grassy vegetation. It does not include temporary grasslands, which are masked out using the corresponding Ploughing indicator (PLOUGH), indicating on the number of years since a pixel was last ploughed. In the 100 meter raster product, the number of Grassland pixels are counted and the percentages stored in each 100 meter cell. The class 255 = outside area is predefined by the 100m boundary layer and remains unchanged. This dataset is provided annually starting in 2017 with 100 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).
