What is reflectance formula?
Calculate reflectance from the reflectivity. Reflectance is the square of the reflectivity so q(y) = (Gr(y)/Gi(y))^2. where q is the reflectance, y is the wavelength of the light, Gr is the reflected radiation and Gi is the incident radiation.
How does the Landsat Collection 1 surface reflectance work?
The Landsat 4-7 Collection 1 Surface Reflectance Product Guide contains details about the LEDAPS algorithm and the Surface Reflectance data products created from it. While both the LEDAPS and LaSRC algorithms produce similar SR products, the inputs and methods to do so differ between them. The table below displays each algorithm.
Where does Landsat 8 provisional aquatic reflectance come from?
The Landsat 8 Provisional Aquatic Reflectance product is derived from Landsat 8 Level-1 (L1) reflective bands over water bodies. Top of Atmosphere (TOA) reflectance and auxiliary atmospheric data are input to an atmospheric correction algorithm to retrieve the water-leaving radiance at visible wavelengths.
Which is the best image from Landsat 8 Collection 2?
Left: Landsat 8 Collection 2 level-1 top of atmosphere reflectance image, center: Landsat 8 Collection 2 level-2 atmospherically corrected surface reflectance image, and right: Landsat 8 Collection 2 level-2 surface temperature image for an area over the Sapta Koshi River in Bairawa, Nepal (path 140 row 41) acquired on May 3, 2013.
Where can I find scene based Landsat data?
Scene-based Surface Reflectance data (on-demand): Processing requests for scene-based Landsat Surface Reflectance data can be submitted from EarthExplorer. The data are located under the Landsat category, Landsat Collection 1 Level-2 (On-Demand)subcategory, with Landsat 8, Landsat 7, and Landsat 4-5 TM listed as individual datasets.
