  1. 6. Mapping tree canopy cover in the semi-arid Sahel using satellite remote sensing and Google Earth imagery

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Abdalla Eltayeb Abdalla Mohamed; [2017]
    Nyckelord :Sahel; physical geography and ecosystem analysis; tree cover; NDVI; Google Earth; Landsat 8; geomatics; Earth and Environmental Sciences;

    Sammanfattning : Tree vegetation is an essential element in the daily life of the people in the Sahel region of Africa. It is also considered as a robust indicator of the Sahel ecosystem status and health. In this thesis, a method to estimate tree vegetation was developed and used in mapping the tree canopy cover in semi-arid Sahel. LÄS MER
