从GeoJSON的转换几何点的经度和纬度

Question

我有一个包含像这样以GeoJSON对象的列表：

{ 
    "type": "Feature", 
    "properties": { 
     "ListEntry": 1440052.000000, 
     "Name": "Edmonton War Memorial", 
     "Location": "Enfield, London, N9", 
     "Grade": "II", 
     "ListDate": "2017\/01\/13", 
     "AmendDate": null, 
     "LegacyUID": null, 
     "NGR": "TQ3435693567", 
     "CaptureSca": "1:1250", 
     "Easting": 534356.190450, 
     "Northing": 193567.535720 
    }, 
    "geometry": { 
     "type": "Point", 
     "coordinates": [ 
      534356.190499999560416, 
      193567.535700000822544 
      ] 
    } 
} 

重的geometry键，一个人如何转换coordinates到传统的纬度和经度，最好是在蟒蛇？

非常感谢。

它看起来并不像在这个条目中有足够的信息来转换为经度和纬度。为此，您还需要点的坐标参考系统。但是，假设以GeoJSON被保存在一个文件中“points.json”你知道对应的坐标参考系的EPSG代码，你可以这样做：

import geopandas as gp 
gdf = gp.read_file("points.json") 
epsg_code = 32630    # my guess based on a quick search, but evidently wrong 
gdf.crs = {"init": "epsg:{}".format(epsg_code)} 
gdf_reprojected = gdf.to_crs({"init": "epsg:4326"}) 

在gdf_reprojected的点是在经度/纬度。
