Radar vegetation indices for monitoring surface vegetation: Developments, challenges, and trends
Science of The Total EnvironmentMonitoring surface vegetation is essential for environmental protection, disaster prevention, and carbon sequestration in forests. However, optical remote-sensing methods and their derivative technologies typically fail to fully meet this requirement due to constraints such as lighting and weather.

Effects of shadows on vegetation indices
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002An important methodology in the remote sensing of biophysical variables is the use of Spectral Vegetation Indices (SVI). An SVI is an algebraic combination of reflectance values from different wavelength bands to produce a single value. Two SVI are evaluated for their usefulness in determining the Fraction of Absorbed Photosynthetically Active ...

Probability and performance of vegetation indices
spie newsroom, 2007A vegetation index (VI) is expressed as the ratio of reflectance of an object at the near infrared (x) to its reflectance at the visible red (y) band. It can also be given as a function of this ratio or the ratio of the linear combinations of x and y. VIs are used in mapping vegetation cover with satellite imagery, with high and low values reflecting ...

Vegetable Distribution and Marketing, Productivity Indicators
Ovidius University Annals, Economic Sciences Series, 2014In recent years, the productivity of agrifood sector rebounded in actuality due to global challenges caused by increasing food demand. Interest in this topic is marked mainly by higher prices of food products due to lower agricultural productivity, cited as one of the causes of the crisis in the long term, [1] and the need to increase productivity ...
