LEDAPS Calibration, Reflectance, Atmospheric Correction Preprocessing Code, Version 2

The ORNL DAAC  is pleased to announce the release of  LEDAPS, version 2 (Landsat Ecosystem Disturbance Adaptive Processing System), a model product which processes Landsat imagery to surface reflectance.

LEDAPS Calibration, Reflectance, Atmospheric Correction Preprocessing Code, Version 2. Data set prepared by J.G. Masek, E.F. Vermote, N. Saleous, R. Wolfe, F.G. Hall, F. Huemmrich, F. Gao, J. Kutler, and T.K. Lim. The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) is a NASA project to map disturbance, regrowth, and permanent forest conversion across the continent (Masek et al., 2006). The LEDAPS processes Landsat imagery to surface reflectance, using atmospheric correction routines developed for the Terra MODIS instrument (Vermote et al., 1997). The original LEDAPS software was developed at NASA GSFC by Eric Vermote, Nazmi Saleous, Jonathan Kutler, and Robert Wolfe with support from the NASA Terrestrial Ecology program (PI: Jeff Masek). This version was adapted by Dr. Feng Gao. It is a stand-alone version of Landsat 1T calibration, TOA reflectance, cloud masking, and atmospheric correction preprocessing chain. This version is designed to work with the standard web enabled EROS L1T product for Landsat-5 and Landsat-7.

This is version 2, the latest version updated to support both old and new metadata formats for Landsat L1T products. This change was necessitated when USGS EROS changed their metadata format in August 2012. The source code, installation and run instructions are provided.

The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
