Description

WorldCover provides a baseline global land cover product at 10 m resolution for 2021 based on Sentinel-1 and 2 data. It was developed and validated in almost near-real time and at the same time maximizes the impact and uptake for the end users. 

The 2021 data features a new algorithm (v200) and is incompatible with the 2020 version. Therefore, no comparison can be drawn from a change in pixel between the 2020 and 2021 versions of ESA WorldCover.

The 2021 version supersedes the earlier 2020 version. For more information about this new and improved update, please see ESA's website and webinar explaining the differences between this version and version 1.

Classes

10. Tree Cover
This class includes any geographic area dominated by trees with a cover of 10% or more. Other land cover classes (shrubs and/or herbs in the understorey, built-up, permanent water bodies, …) can be present below the canopy, even with a density higher than trees. Areas planted with trees for afforestation purposes and plantations (e.g. oil palm, olive trees) are included in this class. This class also includes tree covered areas seasonally or permanently flooded with fresh water except for mangroves.

20. Shrubland
This class includes any geographic area dominated by natural shrubs having a cover of 10% or more. Shrubs are defined as woody perennial plants with persistent and woody stems and without any defined main stem being less than 5 m tall. Trees can be present in scattered form if their cover is less than 10%. Herbaceous plants can also be present at any density. The shrub foliage can be either evergreen or deciduous.

30. Grassland
This class includes any geographic area dominated by natural herbaceous plants (Plants without persistent stem or shoots above ground and lacking definite firm structure): (grasslands, prairies, steppes, savannahs, pastures) with a cover of 10% or more, irrespective of different human and/or animal activities, such as: grazing, selective fire management etc. Woody plants (trees and/or shrubs) can be present assuming their cover is less than 10%. It may also contain uncultivated cropland areas (without harvest/ bare soil period) in the reference year.

40. Cropland
Land covered with annual cropland that is sowed/planted and harvestable at least once within the 12 months after the
sowing/planting date. The annual cropland produces an herbaceous cover and is sometimes combined with some tree or woody
vegetation. Note that perennial woody crops will be classified as the appropriate tree cover or shrub land cover type. Greenhouses are considered as built-up.

50. Built-up
Land covered by buildings, roads and other man-made structures such as railroads. Buildings include both residential and industrial building. Urban green (parks, sport facilities) is not included in this class. Waste dump deposits and extraction sites are considered as bare.

60. Bare or sparse vegetation
Lands with exposed soil, sand, or rocks and never has more than 10 % vegetated cover during any time of the year.

70. Snow and Ice
This class includes any geographic area covered by snow or glaciers persistently.

80. Permanent water bodies
This class includes any geographic area covered for most of the year (more than 9 months) by water bodies: lakes, reservoirs, and rivers. Can be either fresh or salt-water bodies. In some cases the water can be frozen for part of the year (less than 9 months).

90. Herbaceous wetland
Land dominated by natural herbaceous vegetation (cover of 10% or more) that is permanently or regularly flooded by fresh, brackish or salt water. It excludes unvegetated sediment (see 60), swamp forests (classified as tree cover) and mangroves see 95).

95. Mangroves
Taxonomically diverse, salt-tolerant tree and other plant species which thrive in intertidal zones of sheltered tropical shores,
"overwash" islands, and estuaries.

100. Moss and lichen
Land covered with lichens and/or mosses. Lichens are composite organisms formed from the symbiotic association of fungi and algae. Mosses contain photo-autotrophic land plants without true leaves, stems, roots but with leaf-and stemlike organs.

          Your tile layer is ready to use
          This tile layer will automatically create tiles as needed and cache them for future use. No further configuration is required. View the Settings tab to change the default options. Build tiles manually for specific scales and extents to improve display performance for the first person to view the tile layer at that scale and extent. Tiles must exist if the layer will be used offline.
