资源简介:
This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Niwot Ridge LTER, originally collected on 1999-04-04 (17:22:10.4230130Z) by Landsat 5, row 032, path 034. Cloud cover was 50 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.

该长期生态研究网络(Long Term Ecological Research,缩写LTER)遥感空间栅格数据集包含针对尼沃特岭长期生态研究站点(Niwot Ridge LTER)的、经过陆地卫星生态扰动自适应处理系统(Landsat Ecosystem Disturbance Adaptive Processing System,缩写LEDAPS)校正的陆地卫星增强型专题制图仪影像数据。该影像由陆地卫星5号(Landsat 5)于1999年4月4日17时22分10.4230130秒(协调世界时)采集,轨道行号032、轨道路径号034,云覆盖率为50%。
LEDAPS最初由美国国家航空航天局(National Aeronautics and Space Administration,缩写NASA)戈达德太空飞行中心与马里兰大学联合开发,其功能是基于陆地卫星专题制图仪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,缩写USGS)已采用该LEDAPS算法以生成陆地卫星地表反射率气候数据记录。
