Abstract

A significant amount of research has been performed to develop efficient methods for monitoring of vegetation dynamics. A prevailing part of the work is devoted to multispectral data transformation techniques such as spectral bands ratios and linear combinations (vegetation indices) as a mean for vegetation parameters estimation. Vegetation cover fraction and chlorophyll assessment is a main objective in vegetation monitoring. In agriculture, for instance, vegetation amount is related to plant growth monitoring, stress detection and yield forecasting. Here we use colorimetric analysis of spectral reflectance data to examine the sensitivity of vegetation chromaticity features to chlorophyll and canopy fraction changes. Two main factors influence vegetation visible and near infrared reflectance: plant senescence, i.e. chlorophyll inhibition due to plant maturing or as a stress symptom, and soil spectral properties varying with soil type and surface properties. The work was conducted in order to reveal plant senescence effects and soil background impact on vegetation reflectance response and colorimetric characters behaviour.
