GHS-FUA R2019A - GHS functional urban areas, derived from GHS-UCDB R2019A (2015)

The spatial dataset delineates the boundaries of Functional Urban Areas (FUA) of Urban Centres in 2015. The automatic classification procedure developed in collaboration with the OECD estimates for each 1 sq km populated cells outside Urban Centres (obtained from GHS-POP R2019A) the probability of belonging to the commuting zone (or Area Of Influence, AOI) of the closest Urban Centre (GHS-UCDB R2019A). Cells estimated to be part of the AOI are combined and polygonized to form estimated FUA (eFUA) boundaries.

本空间数据集划定了2015年城市中心的功能都市区（Functional Urban Areas, FUA）边界。本研究联合经济合作与发展组织（Organisation for Economic Co-operation and Development, OECD）开发了自动化分类流程，该流程针对源自GHS-POP R2019A数据集的、位于城市中心以外的每1平方千米人口栅格单元，估算其隶属于由GHS-UCDB R2019A数据集得到的最邻近城市中心的通勤区（或影响范围Area Of Influence, AOI）的概率。将被判定属于该影响范围的栅格单元进行合并，并通过多边形化处理生成估算功能都市区（estimated FUA, eFUA）的边界。
