Correcting Landsat Imagery Data: Digital Number to TOA Reflectance for Sun/Earth Geometry, Part 1 of 2

This video, from the Integrated Geospatial Education and Technology Training Project (iGETT), is the first part of a two-part presentation on correcting Landsat imagery data for solar reflectance. The lecture introduces the concept of solar irradiance, brightness and its digital number, and the corrections that should be made to Landsat imagery with software. The seven minute video includes review questions and is intended for a basic level audience.
