Multispectral Remote Sensing.  Multispectral remote sensing is defined as the collection of reflected, emitted, or backscattered energy from an object or area of interest in. multiple bands of electromagnetic spectrum; while Hyperspectral remote. sensing involves data collection in hundreds of bands.
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.Resistors can also be used to provide a specific voltage for an active device such as a transistor.All other factors being equal, in a direct-current (DC) circuit, the current through a resistor is inversely proportional to its resistance, and directly proportional to the voltage across it.esistors can also be used to provide a specific voltage for an active device such as a transistor.

Resistor sources are considered to be the simplest forms of current source. They involve a circuit that contains a resistor in series with a source of voltage. The current generated from this system is equivalent to the amplitude of the voltage, divided by the resistance of the resistor. A resistor current source is generally not considered effective on its own because of the large amount of power lost in the resister, but many types of current source use elements of this setup. For example, active current sources often substitute a different element for the resistor.
