Monitoring and Mapping Vegetation Cover Changes in Arid and Semi-Arid Areas Using Remote Sensing Technology: A Review

Vegetation cover change is one of the key indicators used for monitoring environmental quality. It can accurately reflect changes in hydrology, climate, and human activities, especially arid semi-arid regions. The main goal this paper to review remote sensing satellite sensors methods mapping vegetation semi-arid. Arid lands are eco-sensitive environments with limited water resources cover. Monitoring important regions due scarce sensitive nature plant Due expected cover, land productivity biodiversity might be affected. Thus, early detection assessment their extent severity at local regional scales become very preventing future loss. Remote data useful have been extensively identifying, assessing, such different data, as images, obtained from satellite-based aircraft-based monitor detect changes. By combining remotely sensed e.g., satellites aircraft, ground truth it possible improve accuracy techniques. Additionally, imagery combined ancillary slope, elevation, aspect, bodies, soil characteristics species level. Using analytical methods, then derive indices vegetation.
