Map Viewing Service (WMS) of the dataset: Municipalities of urban unity in the Haut-Rhin

The concept of urban unity is based on the continuity of the building and the number of inhabitants. 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.

城市连片性（urban unity）的判定以建筑连续性与居住人口数量为基础。城市单元（urban unit）指具备连片建成区（两座建筑间的间隔不超过200米）且居住人口至少2000人的单个市镇或多个市镇的集合。若该城市单元仅隶属于单个市镇，则称为独立城镇；若该城市单元跨越多个市镇，且每个相关市镇均将自身超过半数的人口聚集于该连片建成区内，则称为多市镇集聚区。
