Vegetation cover mapping from NOAA/AVHRR

Advances in Space Research, 1985
Abstract The visible and near infrared channels, Ch1 and CH2 respectively, on the Advanced Very High Resolution Radiometer (AVHRR) provide daily information for monitoring changes in vegetation and crops. Data from these channels are used to create a normalized vegetation index (NVI) that is sensitive to changes in green leaf biomass and is ...

Can vegetation indicate landfill cover features?

Flora - Morphology, Distribution, Functional Ecology of Plants, 2011
Generally, great efforts are made in measuring features of landfill covers. However, conventional physical or chemical parameters reach their limits in indicating the small scale changes of the habitats. Bio-indication is a proven tool to assess habitat conditions.

Potential vegetation and potential ecosystem cover

Biology Bulletin Reviews, 2017
A review of literature dedicated to the creation and development of concepts of the potential vegetation and ecosystem cover has been performed. The developmental stages of these concepts are presented in relation to changes in paradigms and the development of historical ecology as a science, allowing an estimation of the depth, intensity, and ...

Method for monitoring vegetation ground covers

2020
A method to be used for the monitoring of vegetation surfaces is described, which includes the use of a device for measuring the spectral reflectance of vegetation using images acquired with a lightining system based on visible and infrared monoband LEDs and including devignetting, image cropping, radiometric calibration procedures and calculation of ...

Aeolian Sand Transport and Vegetation Cover

2008
The Nizzana area has experienced periods of heavy grazing which resulted in the destruction of a cryptogamic soil crust and vegetation cover which, in turn, led to increased aeolian sand movement (Tsoar and Moller 1986). The influence of cryptogamic soil crusts on deflation has been the focus of several studies mainly in drylands used or suitable for ...
