This document describes relevant characteristics of the Collection 1 (C1) Landsat 8 (L8)
Level 2 (L2) Surface Reflectance (SR), Top of Atmosphere (TOA) Reflectance, and
TOA Brightness Temperature (BT) products to facilitate their use in the land remote
sensing community. SR and TOA Reflectance are derived from C1 L8 Operational Land Imager (OLI) Level
1 (L1) data; TOA BT is derived from C1 L8 OLI and Thermal Infrared Sensor (TIRS) L1
data using the Landsat Collection 1 Land Surface Reflectance Code (LaSRC). Information about SR processing of C1 Landsat 4-5 Thematic Mapper (TM) and C1
Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data can be found in the Landsat
4-7 Collection 1 Ecosystem Disturbance Adaptive Processing System (LEDAPS)
Product Guide. Other processing options, such as spectral indices, format conversion, spatial subset,
and/or coordinate system reprojection are described in other product guides and web
pages. This document is under Landsat Satellites Data System (LSDS) Configuration Control
Board (CCB) control. Please submit changes to this document, as well as supportive
material justifying the proposed changes, via Change Request (CR) to the Process and
