ESA WorldCover 2020. Global land cover product at 10 m resolution for 2020 based on Sentinel-1 and 2 data

ESA WorldCover 2020. Global land cover product at 10 m resolution for 2020 based on Sentinel-1 and 2 data

The ESA WorldCover Team has announced the successful development of a new baseline global land cover product at 10m resolution that is developed and validated in almost near-real time and at the same time maximizes the impact and uptake for the end users.

Inspired by the 2017 WorldCover conference organized by ESA, the cardinal requirements of the WorldCover project are:

  • fast generation and validation of a world land cover based on Sentinel-2 and Sentinel-1 constellations
  • 10 land cover classes
  • 10 meters resolution
  • 75% overall accuracy

The WorldCover products are delivered in a regular latitude/longitude grid (EPSG:4326) with the ellipsoid WGS 1984 (Terrestrial radius=6378 km).

The legend includes 11 generic classes that appropriately describe the land surface at 10m: "Tree cover", "Shrubland", "Grassland", "Cropland", "Built-up", "Bare / sparse vegetation”, “Snow and Ice”, “Permanent water bodies”, “Herbaceous Wetland”, “Mangrove” and “Moss and lichen".

Considering the heavy download of the WorldCover map at 10m, a web interface was developed to mainly visualize and interact with data. A left click, anywhere on the layer, highlights the LC-Map label of the selected pixel in the legend description of the left panel.

Consortium

The WorldCover consortium consists of a group of highly experienced major European service providers and research organizations, covering all relevant aspects of land cover mapping including the validation. The consortium has a long track record of collaboration in diverse European and ESA projects, as well as the Copernicus Land and Climate Change Service.

WorldCover has five key end-user  ( UNCCD, OECD, WRI, FAO, CIFOR) which are an integral part of the project and will follow the whole project workflow from design up to validation and uptake.
