资源简介:
This dataset is a seasonal standard deviation time-series of Landsat Analysis Ready Data (ARD)-derived Normalized Difference Vegetation Index (NDVI) computed from Landsat 5 Thematic Mapper (TM) and Landsat 8 Opeational Land Imager (OLI). It complements the seasonal mean dataset. To ensure a consistent dataset, Landsat 7 has not been used because the Scan Line Correct (SLC) failure creates gaps into the data.
NDVI quantifies vegetation by measuring the difference between near-infrared (which vegetation strongly reflects) and red light (which vegetation absorbs) using this generic formula:
(NIR - R) / (NIR + R)
For Landsat sensors, this corresponds to the following bands:
Landsat 5, NDVI = (Band 4 – Band 3) / (Band 4 + Band 3).
Landsat 8, NDVI = (Band 5 – Band 4) / (Band 5 + Band 4).
NDVI values ranges from -1 to +1.
NDVI is used to quantify vegetation greenness and is useful in understanding vegetation density and assessing changes in plant health.
