GHS-DUC R2022A - GHS Degree of Urbanisation Classification, application of the Degree of Urbanisation methodology (stage II) to GADM 3.6 layer, multitemporal (1975-2030) - OBSOLETE RELEASE

OBSOLETE RELEASE - The use of the GHSL Data Package 2022 (GHS P2022) is currently not recommended. CHECK FOR THE MOST UPDATED VERSION OF GHSL DATASETS AT https://ghsl.jrc.ec.europa.eu/datasets.php - This dataset contains the Global Degree of Urbanisation Classification of administrative units delineated by the Global ADMinistrative layer version 3.6 (GADM36) according to the application of stage II of the Degree of Urbanisation. The classification is based on the Global Human Settlement Layer (GHSL) global datasets GHS R2022: the settlement classification GHS-SMOD (GHS-SMOD_GLOBE_R2022A), population grid GHS-POP (GHS-POP_GLOBE_R2022A), and built-up surface GHS-BUILT-S (GHS-BUILT-S_GLOBE_R2022A) layers for target years 1975-2030 (5 years timestep).
This dataset contains a package composed by one excel table, a summary table gathering global summary statistics and by countries and territories in GADM3.6, and 72 CSV files, one per GADM level (from 0 to 5) and epoch (1975-2030), with all administrative units classified according to the Degree of Urbanisation. The spatial delineation of GADM 3.6 administrative units is available at GADM official website (accessible through the link below). Please select the whole world shapefile as six separate layers (one for each level of subdivision/aggregation). The vector layers can be used to join each classification table (csv) with the actual spatial units.

本版本已废弃 — 当前不建议使用全球人居图层（Global Human Settlement Layer, GHSL）2022版数据包（GHS P2022）。请前往https://ghsl.jrc.ec.europa.eu/datasets.php查看GHSL数据集的最新版本。本数据集包含依据城市化程度分类第二阶段应用规则，由全球行政图层3.6版（GADM3.6）划定的行政单元的全球城市化程度分类数据。该分类基于GHSL的GHS R2022系列全球数据集，涵盖1975-2030年（5年时间步长）的三类核心图层：居民点分类图层GHS-SMOD（GHS-SMOD_GLOBE_R2022A）、人口网格图层GHS-POP（GHS-POP_GLOBE_R2022A）以及建成地表图层GHS-BUILT-S（GHS-BUILT-S_GLOBE_R2022A）。
本数据集的数据包包含1个Excel表格、1份汇总全球及GADM3.6框架下各国与地区统计数据的汇总表，以及72个CSV文件：每个CSV文件对应1个GADM层级（0至5级）与1个时间阶段（1975-2030年），收录所有按城市化程度完成分类的行政单元数据。GADM3.6行政单元的空间区划可在GADM官方网站获取（可通过下方链接访问）。请选择全球范围的Shapefile文件，并将其拆分为6个独立图层（分别对应1级细分/聚合层级）。矢量图层可用于将各分类表（CSV文件）与实际空间单元完成关联匹配。
