Correct option is C
Remote sensing involves gathering information about objects or areas from a distance, typically using satellites or aircraft. The given options are all correct descriptions of concepts used in remote sensing:
1.
Lambertian Surface:
· A surface that reflects radiance equally in all directions is known as a Lambertian surface.
· This is crucial for simplifying radiative transfer calculations in remote sensing.
2.
Reflectance:
· Reflectance is the ratio of reflected radiation flux to the incident radiation flux, ranging from
0 to 1.
· It is a key property used to analyze surface characteristics in remote sensing.
3.
Signature:
· The unique combination of properties (such as reflectance, emissivity, etc.) used to identify objects is called their
signature.
· This allows differentiation of objects like vegetation, water, and urban areas in remote sensing imagery.
