What is hyperspectral remote sensing?

hyperspectral remote sensing, also known as imaging spectroscopy, is the use of hyperspectral imaging from a moving sensory device, such as satellite, to collect data about a particular interest. This type of display is a technology that can detect electromagnetic frequencies outside the range of human eye, such as infrared and ultraviolet spectra. The data collected using a hyperspectral remote survey enables the detection of certain elements on the ground or changes that take place in these elements because these elements emit a certain spectral signature and are carried out on wide distances and large areas.

The use of hyperspectral imaging is a very useful hyperspectral imaging can collect the visual representation of the range of spectral signatures and put them in a practical form. Usually each picture taken shows one belt of electromagnetic, and the images are composed of a three -dimensional model. This allows easy comparison with known spectralSignature, such as the type of oil generates, or a specific change that occurs, such as the movement of ground comparison over time. Unlike the hyperspectral imaging made on the ground, remote sensing can cover a large area in a shorter time. With the advent of more sensitive sensors, data collected with a hyperspectral remote survey can now be comparable in quality to the ground.

Until recently, the

main use of this technology has been limited to the mineral industry and, in particular, the detection of new oil fields was used mainly by the oil industry. It is now used in several areas, such as agriculture, where they can be used to determine whether the crop fails or what type of crops produces and which are not. This type of display also uses ecology, geology and forestry. It is also used in the field of physics and offers more detailed analysis and improvement compared to traditional observation methods.

one other posoRunning use for hyperspectral remote sensing is in the area of ​​supervision, especially military supervision. In modern times, there are many ways to avoid detection and hide military installations, weapons or people. Detail available in hyperspectral remote exploration allows you to detect most of everything, because at least some spectral belts will be able to pick up some form of data from the scanned area.
