Deficit zone use green building block

Low with range zone of use green at building block level (150m and 2 min walk). The deficit zone is the residential area that represents the inverse of the given range zone. By green we mean: - publicly accessible greenery for use without surface restriction: parks, pocket parks, hanging green, fort green, dog walking area, city forest, play forest, cemetery, green playgrounds, publicly accessible building green This data layer is updated annually in January, provided that the facility is managed and updated annually by the competent sector / service. In addition to the spatial distribution of facilities at neighborhood, district and district level, with this fine-meshed building block level, we want to draw attention to the importance of the immediate proximity (two minutes walk) of greenery, square or nature, this in function of climate and against heat stress. Important barriers (water, ring, highway, rail, etc.) and safe crossings for vulnerable road users (tunnels, bridges, pedestrian crossings with traffic lights) are also taken into account here.本数据集聚焦街区单元尺度（building block level）下，步行150米或2分钟步行可达范围内绿色空间使用可达性偏低的区域。可达性不足区域为与上述指定可达范围区域呈反向对应的居住区。 本数据集所定义的绿色空间包含：无使用场地限制的公共绿地，具体包括公园、口袋公园（pocket parks）、悬挂式绿化（hanging green）、堡垒绿地（fort green）、遛狗专区、城市森林、户外游戏森林、陵园绿地、绿化游乐场地以及建筑公共绿地（publicly accessible building green）。 本数据图层每年1月更新，前提是相关设施由主管业务的部门/服务机构按年度开展管理与更新维护工作。 除了展示邻里、片区及区级层面的设施空间分布外，本数据集采用精细的街区单元尺度，旨在凸显绿色空间、广场或自然环境步行2分钟可达的重要性，以应对气候变化并缓解热应激问题。 此外，本数据集还纳入了重要阻隔要素（水域、环路、高速公路、铁路等）以及面向弱势道路使用者的安全过街设施（隧道、桥梁、带交通信号灯的人行横道等）。
