Quantifying Vegetation Change in Semiarid Environments: Precision and Accuracy of Spectral Mixture Analysis and the Normalized Difference Vegetation Index
Because in situ techniques for determining vegetation even when applied to areas of low vegetation cover, the SMA approach correctly determined the sense of change abundance in semiarid regions are labor intensive, they usually are not feasible for regional analyses. Remotely (i.e., positive or negative) in 87% of the samples. SMA results are superior to NDVI, which, although correlated sensed ...
متن کاملMapping and Attributing Normalized Difference Vegetation Index Trends for Nepal
Global change affects vegetation cover and processes through multiple pathways. Long 1 time series of surface land surface properties derived from satellite remote sensing give unique 2 abilities to observe these changes, particularly in areas with complex topography and limited research 3 infrastructure. Here, we focus on Nepal, a biodiversity hotspot where vegetation productivity is 4 limited...
