Copernicus Global Land Service - Land Cover 100m

Introduction

Example: Roughness Lines in windPRO based on CGLS-LC100m 2015

The CGLS-LC100 is a dynamic land cover map at 100m resolution and a part of the product portfolio for the Copernicus Global Land Service (CGLS) [1]. It has the target to deliver a yearly, global land cover map which primarily will be based based on PROBA-V – and later to be merged and replaced by Sentinel-2 satellite sources. Currently (2018), a demonstration map covering the continent of Africa has been released. This map was derived from PROBA-V time series combined with local land cover training datasets as well as ancillary datasets.

Spatial and Temporal Coverage

Coverage for the demonstration dataset is the continent of Africa for the year of 2015.
Later the coverage will become global and be at a yearly release schedule. It is based on a 100 m x 100 m grid.

Roadmap

Demonstration dataset for Africa was released in ultimo 2017.
In 2018, adaption of the retrieval methodology to Sentinel-2 data is planned and release of the dataset with global coverage.

Legends

The legend is based on the UN LCCS (United Nations Land Cover Classification System). For the CGLS-LS100 main land cover product, it holds 18 classes, see the sample map image for Tenerife above.

Table: CGLS-LC100 with Roughness Classification Data by EMD

ID	Land Cover Type	EMD Roughness Length	Definition UN LCSS
0	No data	z0=NA	NA
20	Shrubs	z0=0.70000	These are woody perennial plants with persistent and woody stems and without any defined main stem being less than 5 m tall. The shrub foliage can be either evergreen or deciduous.
30	Herbaceous vegetation	z0=0.50000	Plants without persistent stem or shoots above ground and lacking definite firm structure. Tree and shrub cover is less than 10%.
40	Cropland	z0=0.10000	Lands covered with temporary crops followed by harvest and a bare soil period (e.g., single and multiple cropping systems). Note that perennial woody crops will be classified as the appropriate forest or shrub land cover type.
50	Urban / built up	z0=0.40000	Land covered by buildings and other man-made structures.
60	Bare/sparse vegetation	z0=0.02000	Lands with exposed soil, sand, or rocks and never has more than 10% vegetated cover during any time of the year.
7	Mineral extraction sites 1.3.1	z0=0.10000
8	Dump sites 1.3.2	z0=0.10000
9	Construction sites 1.3.3	z0=0.30000
10	Green urban areas 1.4.1	z0=0.40000
11	Sport and leisure facilities 1.4.2	z0=0.50000
12	Non-irrigated arable land 2.1.1	z0=0.05600
13	Permanently irrigated land 2.1.2	z0=0.05600
14	Rice fields 2.1.3	z0=0.01840
15	Vineyards 2.2.1	z0=0.30000
	16	Fruit trees and berry plantations 2.2.2	z0=0.40000
17	Olive groves 2.2.3	z0=0.40000
18	Pastures 2.3.1	z0=0.03600
