LaSRC Product Guide - 2 - Version 4.3 Executive Summary This document describes relevant characteristics of the Landsat 8 Surface Reflectance

For the past several months, I have been hearing from users of ENVI about a new set of provisional Landsat products being provided by the USGS.These products, known as Surface Reflectance High Level Data Products, are generated by specialized software that was originally developed by NASA.The software applies radiometric calibration and atmospheric correction algorithms to Level-1 Landsat … Active 1 year, 2 months ago. The product described here, the Landsat 8 Surface Reflectance Code (LaSRC) is distinctly different from the algorithm used by USGS to process Landsat 4–5 Thematic Information about Surface Reflectance processing of Landsat 8 data can be found in the . I downloaded some Landsat 8 OLI/TIRS C1 Level-1 images from EarthExplorer. The SR product delivers modeled surface reflectance from Landsat TM/ETM+/OLI data using physical rather than empirical models. Landsat 8 Surface Reflectance (Provisional) Product Guide - EarthExplorer Version Version 1.1 May 2015 Department of the Interior U.S. Geological Survey Surface Reflectance Status TM and ETM+ processed through LEDAPS On-demand through EarthExplorer and ESPA Planning transition to operational systems OLI processed through separate code base Currently in “provisional” (Beta) release In the process of documenting code, processing flow, known issues (following slides) Product Guide More information pertaining to the auxiliary data characteristics is described in the LEDAPS and LaSRC Product Guides. The Land Surface Reflectance Code (LaSRC) Product Guide describes the LaSRC algorithm and the Landsat 8 Surface Reflectance data products created from it. In this the scale factor for each bands (1-7) are give specifically as 0.0001. Landsat 8 - Reflectance Values. b. True-color composite of the OLI red (0.630–0.680 μm), green (0.525–0.600 μm) and blue (0.450–0.515 μm) bands. Accordingly, this product will ensure that reflective value differences between imagery acquired at different times by different sensors will be primarily due to on-ground changes in biophysical parameters rather than artifacts of the imaging environment. The Land Surface Reflectance Code (LaSRC) Product Guide describes the LaSRC algorithm and the Landsat 8 Surface Reflectance data products created from it. Table 6-6. A Harmonized Surface Reflectance Product Landsat and Sentinel-2 data represent the most widely accessible moderate-to-high spatial resolution multispectral satellite measurement.

For the past several months, I have been hearing from users of ENVI about a new set of provisional Landsat products being provided by the USGS.These products, known as Surface Reflectance High Level Data Products, are generated by specialized software that was originally developed by NASA.The software applies radiometric calibration and atmospheric correction algorithms to Level-1 Landsat … Viewer¶ You can explore the differences between top-of-atmosphere (TOA) and surface reflectance imagery in Descartes Labs Viewer. Initially, we are offering surface reflectance versions of all Landsat 8 and Sentinel-2 imagery that we ingest.

map algorithm, named LaSRC (Land Surface Reflectance Code), developed by Eric Vermote (NASA GSFC).

Users rely on these data for historical study of land surface change and require consistent radiometric data processed to the highest sci-ence standards.

Date Landsat 47 and the Landsat Surface Reflectance Code (LaSRC) for Landsat 8. a. Prototype Landsat 8 OLI surface reflectance product derived from a 185 km × 180 km L1T image acquired over Chesapeake Bay, MD, USA, April 21 2013.

(2016). A comparison here shows that Landsat 8 and Sentinel-2 imagery on the same date only 15 minutes apart both converted to surface reflectance with the Frequency 50 - .008 method, have similar values to each other and USGS Landsat 8 Algorithm Surface Reflectance.

Landsat 8 Surface Reflectance (Provisional) Product Guide - EarthExplorer Version Version 1.1 May 2015 Department of the Interior U.S. Geological Survey Landsat Surface Reflectance Data Landsat satellite data have been produced, archived, and distributed by the U.S. Geological Survey (USGS) since 1972. When creating or editing a layer select a processing level (TOA or Surface) if it applies to the product.
