LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Central Arizona - Phoenix LTER collected on 1998-08-21

This LTER Remote Sensing spatial raster dataset consists of LEDAPS corrected Landsat Enhanced Thematic Mapper image data for Central Arizona - Phoenix LTER, originally collected on 1998-08-21 (17:35:57.8670630Z) by Landsat 5, row 36, path 36. 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.

本长期生态研究网络（Long-Term Ecological Research, LTER）遥感空间栅格数据集，涵盖亚利桑那中部-凤凰城LTER区域经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1998年8月21日17时35分57.8670630秒（协调世界时）采集，轨道行号36、轨道路径号36，云量覆盖率为50%。陆地卫星生态扰动自适应处理系统（Landsat Ecosystem Disturbance Adaptive Processing System, 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）及增强型专题制图仪Plus（Enhanced Thematic Mapper Plus）的一级数字数值，生成大气层顶反射率数据，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（Landsat Surface Reflectance Climate Data Record）。相关元数据来源如下：美国国家航空航天局陆地卫星项目，2009年；陆地卫星专题制图仪（Landsat TM）LT50360361998233XXX01，LPGS_12.0.2版本；美国地质调查局，苏福尔斯，2012年8月18日08时35分40秒（协调世界时）。
