OpenStreetMap Medical Facilities for North America

This feature layer provides access to OpenStreetMap (OSM) polygon data of medical facilities for North America, which is updated every 15 minutes with the latest edits. This hosted feature layer view is referencing a hosted feature layer of OSM polygon (way) data in ArcGIS Online that is updated with minutely diffs from the OSM planet file. This feature layer view includes amenity and building features defined as a query against the hosted feature layer where amenity or building value is any of 'hospital', 'clinic', 'doctors', or 'pharmacy'. In OSM, amenities are useful and important facilities for visitors and residents, such as hospitals and clinics. These features are identified with an amenity tag. In OSM, a building is a man-made structure with a roof, standing more or less permanently in one place. These features are identified with a building tag. There are thousands of different tag values used in the OSM database. In this feature layer, unique symbols are used for the most common amenity and building tags used for medical facilities. Zoom in to large scales (e.g. City level or 1:160k scale) to see the amenity features display. You can click on a feature to get the name of the feature. The name of the feature will display by default at very large scales (e.g. Building level of 1:2k scale). Labels can be turned off in your map if you prefer.本要素图层可访问北美地区的开放街道地图（OpenStreetMap, OSM）医疗设施多边形数据，每15分钟同步最新编辑内容完成更新。此托管要素图层视图引用了ArcGIS Online中的OSM多边形（way）数据托管要素图层，该图层通过同步来自OSM全球文件的分钟级差异数据实现更新。本要素图层视图包含设施标签（amenity）与建筑标签（building）两类要素，其查询规则为：对托管要素图层进行筛选，仅保留amenity或building取值为'hospital'、'clinic'、'doctors'或'pharmacy'的要素。在OSM体系中，设施标签（amenity）指代为访客与居民提供服务的实用重要公共设施，例如医院、诊所等，此类要素通过amenity标签进行标识。在OSM体系中，建筑指带有屋顶、基本永久固定于一处的人造构筑物，此类要素通过建筑标签（building）进行标识。OSM数据库内共使用数千种不同的标签取值。本要素图层针对医疗设施场景下常用的amenity与building标签，配置了专属的差异化符号样式。请放大至较大比例尺（例如城市级别或1:160000比例尺）方可正常显示设施标签要素。点击任意要素即可查看其名称，在极高比例尺下（例如建筑层级的1:2000比例尺），要素名称将默认显示。若您无需显示标签，可在地图中关闭该功能。
