Linearized Vegetation Indices Using a Formal Statistical Framework
نویسندگان
چکیده
Vegetation indices have been used extensively to estimate the vegetation density from satellite and airborne images for many years. In this paper we first focus on one of the most popular vegetation indices, the normalized difference vegetation index (NDVI ) [1] and introduce a statistical framework to analyze it. We propose a solution to the saturation problem of this index based on our statistical framework. We investigate the relationship of this index with the ratio vegetation index (RVI ) [2], another popular measure. Using the established statistical framework, we introduce new vegetation indices using blue and green bands in addition to the red and the near-infrared.

Remote estimation of crop fractional vegetation cover: the use of noise equivalent as an indicator of performance of vegetation indices
Many algorithms have been developed for the remote estimation of vegetation fraction in terms of combinations of spectral bands, derivatives of reflectance spectra, neural networks, inversion of radiative transfer models, and several multi-spectral statistical approaches. The most widespread type of algorithm used is the mathematical combination of visible and near-infrared reflectance, in the ...

Ž In the last two decades, numerous investigators have proposed cumulative vegetation indices i.e., functions which . encode the cumulative effect of NDVI maximum value composite time-series into a single variable for net primary Ž . productivity NPP mapping and monitoring on a regional to continental basis. In this paper, we investigate the relationships among three of the most commonly used c...
متن کاملA Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies
In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...
