LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Coweeta LTER collected on 2010-07-23

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Coweeta LTER, originally collected on 2010-07-23 (15:56:39.0800440Z) by Landsat 5, row 36, path 18. Cloud cover was 2.58 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.

本数据集为长期生态研究（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（Enhanced Thematic Mapper, ETM+）影像数据。该影像由陆地卫星5号（Landsat 5）于2010年7月23日15时56分39.0800440秒（协调世界时）采集，轨道行号为36、路径号为18，云量占比为2.58%。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（Thematic Mapper, TM）及增强型专题制图仪Plus的一级数字量化值，计算大气层顶反射率，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。本数据集相关引用信息：美国国家航空航天局陆地卫星计划，2009年；影像标识为Landsat TM LT50180362010204EDC00，处理版本为LPGS_12.0.2；发布机构为美国地质调查局苏福尔斯分部，发布时间为2012年8月21日06时22分54秒（协调世界时）。
