30m land use and cover maps for the Sahel Region in Africa (1990-2020)

30m land use and cover maps for the Sahel Region in Africa (1990-2020)

This data set is a 30m land use / cover classification product in the Sahel region of Africa every five years from 1990 to 2020. The product is based on a collaborative framework of land cover classification integrating machine learning and multiple data fusion, and integrates supervised land cover classification with existing thematic land cover maps by using Google Earth engine (GEE) cloud computing platform. The classification system adopts FROM_ GLC classification system includes 8 categories: cultivated land, forest, grassland, shrub, wetland, water body, impervious surface and bare land. The data set has been verified by a large number of seasonal samples in the Sahel region. The overall accuracy of the data set is about 75%, and the accuracy of change area detection is more than 70%. It is also very similar to FAO and the existing land cover map. The data set can provide data support for the sustainable use of land resources and environmental protection in the Sahel region of Africa.

File naming and required software

File naming: the data is stored in GeoTIFF format. The file name is "Sahel30_lc_yyyy.tif", where yyyy represents the year.
Data reading method: software or computer language that can read GeoTIFF can read the data, such as ArcGIS, envi, IDL, python, MATLAB, etc.
