TLDR
In this paper, a method has been developed for quantitative measurement of vegetation conditions over broad regions using ERTS-1 spectral bands 5 and 7, corrected for sun angle, which is shown to be correlated with aboveground green biomass on rangelands.Abstract:
The Great Plains Corridor rangeland project utilizes natural vegetation systems as phenological indicators of seasonal development and climatic effects upon regional growth conditions. A method has been developed for quantitative measurement of vegetation conditions over broad regions using ERTS-1 MSS data. Radiance values recorded in ERTS-1 spectral bands 5 and 7, corrected for sun angle, are used to compute a band ratio parameter which is shown to be correlated with aboveground green biomass on rangelands.read more

A Physically-Based Transformation of Thematic Mapper Data---The TM Tasseled Cap
Eric P. Crist,Richard C. Cicone +1 more
TL;DR: In an extension of previous simulation studies, a transformation of actual TM data in the six reflective bands is described which achieves three objectives: a fundamental view of TM data structures is presented, the vast majority of data variability is concentrated in a few features, and the defined features can be directly associated with physical scene characteristics.

Hyperspectral Vegetation Indices and Their Relationships with Agricultural Crop Characteristics
TL;DR: In this article, three types of hyperspectral predictors were tested: optimum multiple narrow band reflectance (OMNBR), narrow band normalized difference vegetation index (NDVI), and the soil-adjusted vegetation indices.

The interpretation of spectral vegetation indexes
TL;DR: In this article, the spectral derivative of surface reflectance with respect to wavelength is used as a measure of chlorophyll abundance and energy absorption in the leaves of a broadband and near-infrared vegetation index.
