Global 1/8-Degree Urban Land Fraction Grids, SSP-Consistent Projections and Base Year, v1 (2000 - 2100)

Global time-series maps of the fraction of urban land to all land area at 1/8-degree spatial resolution, including the base year (2000), projections (2010-2100) consistent with the Shared Socioeconomic Pathways (SSPs), and two ancillary layers: (i) total land area, and (ii) the fraction of land available for development to all land area, at 1/8-degree resolution. Downloadable in three data formats: GeoTIFF, NetCDF, and Esri Grid. Data Unit: dimensionless for urban and available land fractions; km2 for total land areas. Cite as... Gao, J., & O'Neill, B.C.

本数据集包含空间分辨率为1/8度的全球城市用地占总用地比例时序地图，涵盖基准年（2000年），以及与共享社会经济路径（Shared Socioeconomic Pathways，SSPs）一致的2010-2100年预测结果；同时附带两个辅助图层：(i) 总土地面积，(ii) 可开发用地占总用地比例，二者空间分辨率均为1/8度。该数据集支持三种格式下载：GeoTIFF、NetCDF及Esri Grid。数据单位说明：城市用地与可开发用地占比为无量纲值；总土地面积单位为平方千米（km²）。引用格式：Gao, J. 与 O'Neill, B.C.
