2018 Land Cover Map of Chongoroi, Angola

Year published: 08/10/2022

The 2018 land cover map of Chongoroi, Angola has been developed as part of the process of land degradation assessment in the area from 2001 to 2021. A stratified random sampling by land cover class was used for training data collection in Collect Earth Online (CEO). Land cover legend classes are prepared using LCML/LCCS v3. A temporal segmentation has been applied to Landsat image collections over the area of interest using the continuous change detection and classification (CCDC) algorithm in SEPAL platform. CCDC slice for 1 July 2018 has been used to generate the 2018 land cover map of Chongoroi by using a random forest classification algorithm in Google Earth Engine (GEE).
