还有两个想法:
1)只读的Overpass API。我不知道一次就能在整个美国使用,但是也许您可以延长时间...?对于较小的区域(最大.5度),并且受益于(最小)UI,您可以通过XAPI查询生成器访问“ 立交”。在那里,您可以在标签搜索中输入amenity = hospital,选择您的区域,然后继续。
2)如如何提取大区域的部分数据中所述,使用渗透压过滤的Geofabrik下载。在OpenStreetMap帮助中。
Nominatim可以做到这一点,但在大规模上,下载USA摘录并使用自己的摘录会更有效。
命名示例:
http://nominatim.openstreetmap.org/search?q=usa [医院]&format = json&polygon = 0&addressdetails = 1
返回值:

对于xml用xml替换json

您最好在这里提问:https : //help.openstreetmap.org/
该网站可以为您提供正确的信息;http://osm2shp.ru/它可能是过时的(2016),但它会给你用所有的医院amenity_pnt和使用所有救护站emergency_pnt。然后,您可以将其导入QGIS并进行过滤。
您看过CloudMade下载网站吗?它们为特定区域提供各种格式的数据。这可能有您所需的数据?
