Annual Detection of Forest Cover Loss Using Time Series Satellite Measurements of Percent Tree Cover
We introduce and test a new method to detect annual forest cover loss from time series estimates of percent tree cover. Our approach is founded on two realistic assumptions: (1) land cover disturbances are rare events over large geographic areas that occur within a short time frame; and (2) spatially discrete land cover disturbances are continuous processes over time. Applying statistically rig...
متن کاملVariation of Plant Functional Groups along Livestock Grazing Gradient in Semi-steppe Rangelands (Case Study: Tangsayad Rangelands of Chaharmahal Bakhtiari Province, Iran)
Assessment and monitoring of rangeland in different grazing managements seems necessary to manage rangelands. The plant functional groups can be used as appropriate responders for rangelands condition and management. Therefore, this study was performed and aimed to determine the most important traits that are influenced by rangeland variation and management. In order to this, three areas along ...
متن کاملVegetation cover change detection using RS and GIS in Chaharbagh rangelands of Golestan province for a period of 30-years
Using accurate and low-cost methods to monitor quantitative changes in vegetation cover play an important role in the efficient and sustainable management when the area is too large. In this study, the changes of vegetation cover were investigated using satellite data of TM (Landsat_5) and oli (Landsat_8) sensors for a 30-year period (1988-2018) in Chaharbagh rangeland of Golestan province. T...
متن کاملImproving the Accuracy of the Water Surface Cover Type in the 30 m FROM-GLC Product
The finer resolution observation and monitoring of the global land cover (FROM-GLC) product makes it the first 30 m resolution global land cover product from which one can extract a global water mask. However, two major types of misclassification exist with this product due to spectral similarity and spectral mixing. Mountain and cloud shadows are often incorrectly classified as water since the...
متن کاملPreparation of Rangeland vegetation cover map and monitoring its changes in drought and wet periods using NDVI MODIS product (Case Study: Southern Rangelands of Yazd Province)
Knowledge of rangeland vegetation characteristics as well as factors affecting it in environmental planning, land management and sustainable development is very important. However, regional and up-to-date maps of pasture vegetation cover are not always available. In this study, in order to plot the vegetation cover percentage of the rangelands and monitor its changes in drought and wet periods,...
