LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Coweeta LTER collected on 1989-07-29

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Coweeta LTER, originally collected on 1989-07-29 (15:33:16.8690000Z) by Landsat 5, row 36, path 18. Cloud cover was 20 percent. The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) software was originally developed by the National Aeronautics and Space Administration–Goddard Space Flight Center and the University of Maryland to produce top-of-atmosphere reflectance from Landsat Thematic Mapper and Enhanced Thematic Mapper Plus Level 1 digital numbers and to apply atmospheric corrections to generate a surface-reflectance product. The U.S. Geological Survey (USGS) has adopted the LEDAPS algorithm for producing the Landsat Surface Reflectance Climate Data Record.

本长期生态研究（Long Term Ecological Research, LTER）遥感空间栅格数据集，包含针对Coweeta LTER站点的、经陆地卫星生态扰动自适应处理系统（Landsat Ecosystem Disturbance Adaptive Processing System, LEDAPS）校正的陆地卫星增强型专题制图仪（Landsat Enhanced Thematic Mapper）影像数据。该影像由陆地卫星5号（Landsat 5）于1989年7月29日15时33分16.8690000秒（协调世界时）采集，轨道行号为36、路径号为18，云量占比为20%。
LEDAPS最初由美国国家航空航天局戈达德太空飞行中心与马里兰大学联合开发，其功能为基于陆地卫星专题制图仪（Landsat Thematic Mapper, TM）及增强型专题制图仪加（Enhanced Thematic Mapper Plus, ETM+）的一级数字量化值生成大气顶层反射率，并通过大气校正生成地表反射率产品。美国地质调查局（U.S. Geological Survey, USGS）已采用LEDAPS算法，用于生成陆地卫星地表反射率气候数据记录。
