从Google Maps API获取JSON中的City多边形边界吗？

51

在Google Maps中搜索城市时，将显示城市的行政边界。

有没有一种方法可以使用Google Maps API以JSON格式获取City的多边形边界？

相关文章：哪种API方法提供了城市边界图？

Google地图的格式为GeoJson。有一个用于按邮政编码，城市和州进行查询的API，请访问www.boundaries-io.com

您可以使用openstreetmap在json中获取多边形坐标以与googlemaps一起使用。转到http://nominatim.openstreetmap.org/ 搜索“ Partido deItuzaingó”之类的地方

点击“详细信息”

查找OSM ID并将其复制（control + c），例如：2018776

将ID粘贴到 http://polygons.openstreetmap.fr/index.py中，然后下载多边形

polygons.openstreetmap.fr/index.py不再起作用。您可以使用global.mapit.mysociety.org

global.mapit.mysociety.org不适用于巴格达（但原始帖子适用）：首先我在这里得到它：nominatim.openstreetmap.org/details.php? place_id=179724619 ，然后发现关系id为5638803，何时我运行global.mapit.mysociety.org/code/osm_rel/5638803我得到了{"code": 404, "error": "No areas were found that matched code osm_rel = 5638803."}

要获得多边形边界，只需将其添加format=json到您的请求中即可！

所以不是 https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1

采用

https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1&format=json

通过添加＆format = geojson，您可以获得有效的geojson响应

不，没有办法窃取Google的数据。也许您可以看一下供人们下载的OpenStreetMap。

例如，如何在OpenStreetMap中提取多边形边界？如果我提取了此内容，可以在Google地图上绘制提取的多边形吗？

— Luis Tiago

请搜索该网站，并提出一个新的问题，如果您找不到答案

— Ian Turton

谁会考虑这种偷窃行为？该数据取自美国人口普查。

— ihodonald

然后从美国人口普查站点获取它，尽管我怀疑它们在英国的城市边界是否很多

我找到了解决该问题的方法。

前往www.gadm.org/country
选择您的国家/地区，然后选择Google Earth .kmz文件格式
选择您需要的级别（所有小城镇/城市中，级别3最高）
下载文件（可能很大）
解压缩.kmz文件（您将找到一个.kml XML文件）
用Sublime或notepad ++打开它（该文件对于其他文本编辑器可能太大了）
按城市名称搜索并在下面复制数据（大文件搜索可能需要1-4秒）

您可以使用经纬度较长的数据并将其解析为一个数组。该解决方案效果很好，但是路径的质量有时很粗糙。

作为Google Maps API的替代方法，OpenStreetMap可以帮助您在此页面http://nominatim.openstreetmap.org/中按名称搜索城市。然后查看搜索结果，您可以获取GeoJSON格式的区域坐标，例如（http://nominatim.openstreetmap.org/details.php?place_id=145126778）以在管理标签中获取mashhad geojson坐标
