GHS-BUILT R2018A - GHS built-up grid INPUT DATA, Landsat multitemporal collections (1975-1990-2000-2014) - OBSOLETE RELEASE

Multi-temporal information layers on footprint and metadata of Landsat scenes used in the production of GHS BUILT grid R2018A. The scenes are organised in imge data collections, and were prepared by the Global Land Survey (GLS1975, GLS1990, GLS2000) and by the JRC (Landsat 8 collection for 2014).本数据集为用于生成GHS建筑栅格R2018A版（GHS BUILT grid R2018A）的陆地卫星（Landsat）影像覆盖范围与元数据的多时序信息图层。该系列影像被整理为影像数据集，由全球土地调查（Global Land Survey, GLS）的GLS1975、GLS1990、GLS2000项目，以及欧盟联合研究中心（Joint Research Centre, JRC）针对2014年的陆地卫星8号影像集完成制备。
