Sioux Falls, South Dakota - iii - LSDS-1368 Version 2.0 . Yeah! Landsat Collections Tiers. 2. The Landsat scene center solar elevation for the tutorial imagery is 61.44223464. Landsat Collection 1 Surface Reflectance measures the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor. All Landsat Level 1 data that meet the following criteria are accepted for surface reflectance processing: • Landsat 8: Most Operational Land Imager (OLI) scenes acquired from April 11, 2013, to within 1 …

Landsat Collections consist of three tiered categories: Real-Time, Tier 1, and Tier 2.

USGS Landsat 8 Collection 1 Tier 1 and Real-Time data TOA Reflectance (Orthorectified) May 11, 2017 thisearthsite Google Earth Engine, Javascript, Landsat Leave a comment. Skip to content. Landsat Collections Landsat Collection 1 Landsat Collection 1 consists of Level-1 data products generated from Landsat 8 Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), Landsat 4-5 Thematic Mapper (TM)*, and Landsat 1-5 Multispectral Scanner (MSS) instruments.

May 2019 . The Collection data products for Landsat 1-7 are cross-calibrated to L8 OLI and provide two sets of scaling factors, one to calculate the TOA reflectance and the other to calculate TOA radiance, just as it has always been the case for L8 OLI. Level-1 data are delivered as Digital Numbers (DN) in an unsigned 16-bit integer format and can be converted to Top of Atmosphere (TOA) reflectance or radiance using the radiometric scaling factors provided in each scene metadata file. Landsat 8 OLI Collection 2 Surface Reflectance data are generated using the Land Surface Reflectance Code (LaSRC) (version 1.5.0), which makes use of the coastal aerosol band to perform aerosol inversion tests, uses auxiliary climate data from MODIS, and a unique …
Landsat Collection 2 Level-1 data naming convention and band identifiers follow the same nomenclature as Landsat Collection 1.

TX = Collection Category: "RT" for real-time, “T1” for Tier 1 , or "T2" for Tier 2 New Landsat 8 Metadata File Parameter: Scene Select Mirror (SSM) Model In April 2016, a new parameter (TIRS_SSM_MODEL) will be added to the Landsat 8 data metadata (MTL.txt) file, to help users identify the effects of the SSM encoder current anomaly. May 2019 - ii - LSDS-1368 Version 2.0 . Executive Summary This document describes relevant characteristics of the Landsat 8 …

The cosine of the solar zenith angle for the data in the tutorial is 0.87833560.


new data! I downloaded some Landsat 8 OLI/TIRS C1 Level-1 images from EarthExplorer. Explorer (https://earthexplorer.usgs.gov), under the “Landsat” datasets. Explorer (https://earthexplorer.usgs.gov), under the “Landsat” datasets. As a reminder, reflectance values range from 0.0 to 1.0 and are stored in floating point data format.
