WebJul 3, 2024 · There is a digital number in the Xmp.Camera.SunSensor Tag and I have found a formula to calculate the physical radiance from it. But I don´t understand how the scalar for the radiometric calibration is calculated (I assume there is a scalar between 0 and 1 and every pixel of the raw image is multiplied with that scalar to get the reflectance ... WebLandsat Collection 2 surface temperature has a scale factor of 0.00341802 and an additional offset of 149.0 per pixel. For example, a pixel value of 44,947 is multiplied by 0.00341802 for the scale factor and 149.0 is added for the additional offset to get 302.6 Kelvin after the scale factor is applied.

Digital Number (DN) The generic term for pixel values is Digital Number or DN. It is commonly used to describe pixel values that have not yet been calibrated into physically meaningful units. cushion chairs amazon
