Global Urban Polygons and Points Dataset (GUPPD), Version 1

The Global Urban Polygons and Points Dataset (GUPPD), Version 1 is a global data set of 123,034 urban settlements with place names and population for the years 1975-2030 in five-year increments. The data set builds on and expands the European Commission, Joint Research Centre's (JRC) 2015 Global Human Settlement (GHS) Urban Centre Database (UCDB). The JRC Settlement Model (GHS-SMOD) data set includes a hierarchy of urban settlements, from urban centre (level 30), to dense urban cluster (level 23), to semi-dense urban cluster (level 22). The UCDB only includes level 30, whereas the GUPPDv1 adds levels 23 and 22, and uses open data sources to both check and validate the names that JRC assigned to its UCDB polygons and to label the newly added settlements. The methodology described in the documentation was able to consistently label a greater percentage of UCDB polygons than were previously labeled by JRC.

《全球城市多边形与点数据集》（GUPPD）版本1，是一个包含123,034个城市聚落的全局数据集，其中包含地名和1975年至2030年间的五年增量人口数据。该数据集在欧盟委员会联合研究中心（JRC）2015年全球人类聚居（GHS）城市中心数据库（UCDB）的基础上进行扩展。JRC聚落模型（GHS-SMOD）数据集包含城市聚落的层次结构，从城市中心（第30级）到密集城市簇（第23级），再到半密集城市簇（第22级）。UCDB仅包含第30级，而GUPPDv1增加了第23级和第22级，并利用开放数据源对JRC分配给其UCDB多边形的名称进行核实与验证，同时对新增聚落进行标注。文档中描述的方法能够持续地对UCDB多边形进行标注，其标注比例高于JRC先前标注的比例。
