Radiometric Correction

Radiometric correction is an indispensable procedure in the field of remote sensing and image processing to enhance the precision and uniformity of satellite and airborne imagery. Radiometric correction minimizes variations in pixel values due to the influence of various radiometric factors like sensor properties, atmospheric effects, lighting variations, and so forth. Through the correction of such variations, radiometric correction ensures that the images' pixels better represent the true energy emitted or reflected by the Earth's surface. The technique is commonly applied in GIS studies, satellite image interpretation, environmental monitoring, land cover classification, agricultural studies, forestry, disaster management, and earth observation studies among many other areas. Radiometric correction plays an important role in improving the reliability of multispectral and hyperspectral imagery through creating more compatible datasets for comparisons across various temporal, sensorial, and acquisition factors.
