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

The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) was 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, Version 2, was adapted by Dr. Feng Gao, and is a stand-alone version of Landsat 1T calibration, TOA reflectance, cloud masking, and atmospheric correction preprocessing chain. The Version 2 LEDAPS software was designed to work with the standard "web enabled" EROS L1T product for Landsat-5 and Landsat-7, and supports both historic and current EROS metadata models. The LEDAPS code is now part of the National Satellite Land Remote Sensing Data Archive at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center, and distributed through Git Hub.

陆地生态系统扰动自适应处理系统（LEDAPS）是美国国家航空航天局（NASA）的一项项目，旨在绘制整个大陆的扰动、恢复生长以及永久性森林转化的图景（Masek 等人，2006年）。LEDAPS通过运用为Terra MODIS仪器开发的气溶胶校正程序（Vermote 等人，1997年），对Landsat影像进行处理，以获得地表反射率。最初版本的LEDAPS软件由NASA戈达德航天中心（GSFC）的Eric Vermote、Nazmi Saleous、Jonathan Kutler和Robert Wolfe开发，并得到了NASA陆地生态学计划的资助（项目负责人：Jeff Masek）。本版本，即版本2，由高风博士改编，是Landsat 1T校准、TOA反射率、云掩膜和大气校正预处理链的独立版本。版本2的LEDAPS软件旨在与标准“网络启用”的EROS L1T产品兼容，适用于Landsat-5和Landsat-7，并支持历史和当前的EROS元数据模型。目前，LEDAPS代码已成为美国地质调查局（USGS）地球资源观测与科学（EROS）中心的国家卫星陆地遥感数据档案的一部分，并通过Git Hub进行分发。
