Remote sensing is a collection of spatiotemporal views (images) of Earth's surface from vantage points, high above Earth. Such a collection has become instrumental to monitor and predict the future biophysical changes on Earth's surface that human beings will need to overcome. By using remote sensing techniques that involve the interpretation of reflective and absorptive properties of electromagnetic radiations (EMR), image interpreters are able to predict sea surface temperatures, wind patterns, the health of vegetation, possible occurrences of fire based on the structures of various plant canopy, and many other environmental factors. The EMR is absorbed and reflected by both the biological and physical objects of the Earth.

The solar radiation distribution among the vegetation is a function of canopy structure that strongly affects the productivity ...
