The atmosphere influences the amount of electromagnetic energy that is sensed by the detectors of an imaging system and these effects the wavelength transmitted. When electromagnetic radiation travels through the atmosphere, it may be absorbed or scattered by the several particles of the atmosphere. Atmospheric absorption affects mainly on visible and infrared bands which reduces the solar radiance within the absorption bands of the atmospheric gases. Atmospheric scattering is important only in the visible and near infrared regions. Scattering of radiation is caused by the gases and aerosols in the atmosphere which affects the degradation of the remote sensing images. Most noticeably, the solar radiation scattered by the atmosphere towards the sensor without first reaching the ground produces a hazy appearance of the image. However, there are a method that uses in term of correcting the atmospheric haze effects. One of them is Dark Object Subtraction Technique in image base atmospheric correction method which is simple and effective as they require the image data to estimate the radiance of the wavelength.
