Data batch direct download service (WFS): New-Aquitaine: Urban Units (UU) — INSEE 2015

This data batch contains the perimeter data sets of the Urban Units and the municipalities belonging to an Urban Unit (INSEE-2015), in the New Aquitaine region. An urban unit is a municipality or group of municipalities with a continuous building area (no cut-off of more than 200 metres between two buildings) with at least 2,000 inhabitants. If the urban unit is located in a single municipality, it is referred to as an isolated city. If the urban unit extends over several municipalities, and each of these municipalities concentrates more than half of its population in the continuous built-up area, it is referred to as a multi-communal agglomeration本次数据批次包含新阿基坦大区（New Aquitaine）内的城市单元（Urban Unit）及其所属市镇的边界数据集，相关标准采用INSEE-2015。 城市单元指具备连续建成区域（任意两栋建筑的间隔不超过200米）且常住人口不少于2000人的单个市镇或市镇集群。 若某城市单元仅涵盖单个市镇，则称其为独立城市；若城市单元跨越多个市镇，且各相关市镇的半数以上人口均集中于该连续建成区域内，则称其为多市镇集聚区。
