The reference spectra may consist of white, grey and black panels that are placed on the ground in a visible location. A spectral radiometer is then used to measure the reflectance of each calibration panel.

WebIt is possible to manually convert these DNs to ToA Reflectance using a two-step process. The first step is to convert the DNs to radiance values using the bias and gain values specific to the individual scene you are working with. The second step converts the radiance data to ToA reflectance. The Landsat 8 OLI sensor is more sensitive so these ...
