# ESA Climate Change Initiative Land Cover at 300m spatial resolution¶

Date modified: 16 February 2022

## Product Overview¶

### Background¶

Digital Earth Africa (DE Africa) provides free and open access to a copy of ESA’s Climate Change Initiative Land Cover product over Africa for 1992-2019.

Among many potential uses, the CCI Land Cover product aims to:

• build on the United Nations (UN) Food and Agriculture Organization (FAO) Land Cover Classification System (LCCS) for the sake of compatibility with other land cover products;

• meet the needs of climate and global carbon flux modelling communities.

The CCI maps were designed to be globally consistent. Therefore, their “level 1” legend was determined by the level of information that was available and that made sense at the scale of the entire world. This “level 1” legend is the one expressed by ten values (i.e. class values of 10, 20, 30, etc.). The land cover maps were also described by a more detailed legend, called “level 2” which corresponds to the non-ten values (i.e. class values of 11, 12, 61, 62, etc.). This “level 2” legend made use of more accurate and regional information where available.

Further information is available at the ESA landcover CCI website and in the user manual. A Jupyter Notebook which demonstrates loading and using landcover datasets in the Sandbox is also available.

### Processing¶

The ESA Climate Change Initiative Land Cover maps were made with a dominance of MERIS FR imagery. The MERIS RR dataset was also used to compensate for a lack of MERIS FR acquisitions in some areas and observations acquired by the SPOT. Vegetation (SPOT-VGT) were used to extend the temporal coverage of the project over the years 1998-2002.

The multi-year global land cover mapping at 300 M and characterization for climate modelling document and land cover mapping framework paper describe the pre-processing and classification chains used to produce the most recent distibution of land cover maps.
