Population density Wuppertal

The data set “population density Wuppertal” describes the population density in the city of Wuppertal by means of a kilometre quadratraster, which is defined by the kilometre coordinate lines of the official location reference system ETRS89/UTM32. The Wuppertal city area is located in 220 of the square grid cells formed by this, with an area of 1 square km each. The dataset contains the geometries of these grid cells as closed polygons, for which the name of the grid cell (attribut NAME), if applicable the number of persons reported with main residence in this cell (Attribut EW_KM2) and a classification of the population density in four density classes (Attribut KAT) (Class 1: 0 to 300 persons, class 2: 301 to 749 persons, class 3: 750 to 1249 persons, class 4: from 1250 people). The grid cells are designated by the kilometre coordinates of the respective south-western corner point (false Easting without UTM zone numbers 1 to 3 followed by Northing digits 3 and 4). The anonymised data on the registered persons will be taken over from the VOIS/MESO specialist procedure of the Residents Registration Office. The Open Data record available in Shape, KML and GeoJSON format under an Open Data License (CC BY 4.0) is automatically updated in a fixed, weekly cycle.本数据集“伍珀塔尔人口密度（population density Wuppertal）”以千米方格栅格为载体，刻画伍珀塔尔市的人口密度分布。该栅格体系由官方位置参考系统ETRS89/UTM32的千米坐标线划定。伍珀塔尔市域范围覆盖该栅格体系下的220个栅格单元，每个单元面积为1平方千米。数据集包含各栅格单元的闭合多边形几何信息，附带三类属性字段：其一为栅格单元名称（NAME）；其二为该单元内主要居住地登记人口数（EW_KM2，仅适用于存在登记数据的情况）；其三为人口密度分级属性（KAT），该分级将人口密度划分为四个等级：等级1：0至300人，等级2：301至749人，等级3：750至1249人，等级4：1250人及以上。各栅格单元以其西南角的千米坐标进行命名：先取不带UTM分区编号的东伪偏移值（1至3位），后接北偏移值的第3、4位数字。本数据集所使用的匿名化登记人口数据，源自居民登记处的VOIS/MESO专项处理流程。该开放数据记录支持以Shape、KML及GeoJSON格式获取，采用CC BY 4.0开放数据许可协议，并按照固定的每周周期自动更新。
