About this document
Convert Digital Numbers to Radiance by Mohd Epy Azrai is a document available to read on EtoBox.
The document describes the process of converting digital number values from Landsat images to spectral radiance and then to land surface temperature in Kelvin and Celsius. It involves using ENVI software to apply equations that convert digital numbers to spectral radiance using calibration minimum and maximum values, then converting spectral radiance to temperature in Kelvin using sensor-specific calibration constants, and finally calculating temperature in Celsius by subtracting 273 from the Kelvin tempera
