LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Shortgrass Steppe collected on 1993-01-22
收藏资源简介:
This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Shortgrass Steppe, originally collected on 1993-01-22 (16:59:00.9360500Z) by Landsat 5, row 032, path 033. Cloud cover was 30 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(LTER)遥感空间栅格数据集,包含针对短草草原的、经LEDAPS(Landsat生态扰动自适应处理系统)校正的Landsat增强型专题制图仪(Enhanced Thematic Mapper)影像数据。该数据由陆地卫星5号(Landsat 5)于1993年1月22日16时59分00.9360500秒(协调世界时)采集,轨道行号032、轨道路径号033,云量覆盖率为30%。 Landsat生态扰动自适应处理系统(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Landsat专题制图仪(Thematic Mapper, TM)及增强型专题制图仪Plus(Enhanced Thematic Mapper Plus, ETM+)的一级数字数值,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(USGS)已采用LEDAPS算法,用于生成Landsat地表反射率气候数据记录。 数据来源信息:美国国家航空航天局Landsat项目组,2009年;Landsat TM影像编号LT50330321993022XXX02,处理版本LPGS_12.1.3;美国地质调查局(USGS)苏福尔斯分部,2012年12月22日08时00分52秒(协调世界时)。
