Landsat 8 Imagery & Reflectance Tutorial - Free

Includes DOS, COST, and TOA reflectance

(Continuous Relative Scatter, Lowest Valid Value, and Dark Object haze removal methods; includes .MTL file text)

Data download includes blue, green, red, near-infrared (NIR), short-wave infrared (SWIR), and LandsatLook imagery; guide and values to calculate reflectance are included below.  See the information below about the easier Landsat 8 DOS surface reflectance method (the correct image-based atmospheric correction method for Landsat 8).

File with RP includes recently reprocessed imagery (the USGS started reprocessing all imagery February 3, 2014, to improve accuracy; this had a minor impact for bands included in tutorial data as can be seen in the before and after values listed). Steps to calculate reprocessed imagery reflectance are included in tutorial.
