Question

这是我的代码，用于为Google Takeout json文件中的照片添加GPS：

if __name__ == '__main__':
    from sys import argv
    opt = OptionParser()
    opt.add_option('-l', '--location')
    # not sure what this timezone offset is because before 
    # day light saving it was set to 0 and was working maybe it time shift
    opt.add_option('-t', '--timezone')
    (options, args) = opt.parse_args()
    if options.location is None or len(args) != 1:
        print "usage %s [--timezone <hours shift>] --location [History JSON File] <IMAGE FILE>" % argv[0]
    else:
        gps_list = json.loads(open(options.location).read())
        date = parse_date(get_date_taken(args[0]))
        if options.timezone is not None:
            loc = get_gps(gps_list, date, -float(options.timezone))
        else:
            loc = get_gps(gps_list, date)
        found = datetime.fromtimestamp(
            int(loc['timestampMs']) / 1000.0
        )
        print "%s == %s" % (date, found)
        # this conversion seems to be correct (get it from other SO question)
        print loc
        print "lat: %s" % str(int(loc['latitudeE7']) / 1e7)
        print "long: %s" % str(int(loc['longitudeE7']) / 1e7)
        call([
            'exiftool',
            '-m',
            '-GPSLatitude=%s' % str(int(loc['latitudeE7']) / 1e7),
            '-GPSLongitude=%s' % str(int(loc['longitudeE7']) / 1e7),
            args[0]
        ])

我已经检查了this GPS checker处单张照片的输出，该位置大约是正确的，但是当我将GPS添加到图片并将其上传到pic2map.com时，距离已经很近了（几公里）在另一个方向）。

您是否知道其他任何GPS位置检查器，可能pic2map不正确并显示错误位置。还是exif工具接受不同的数据。如果是这样，我该如何校正exif工具数据以获得正确的GPS定位照片。（我主要是想为flickr安装GPS，因此将其添加到GPS定位服务中可以正确搜索GPS。）

外卖json看起来像这样：

{
  "locations" : [ {
    "timestampMs" : "1406974281661",
    "latitudeE7" : 511162000,
    "longitudeE7" : 208802232,
    "accuracy" : 19
  }, {
    "timestampMs" : "1406974327231",
    "latitudeE7" : 511161756,
    "longitudeE7" : 208801345,
    "accuracy" : 7
  }, {
    "timestampMs" : "1406974373278",
    "latitudeE7" : 511161741,
    "longitudeE7" : 208801377,
    "accuracy" : 7,
    "activity" : [ {
      "timestampMs" : "1406974371946",
      "activity" : [ {
        "type" : "IN_VEHICLE",
        "confidence" : 63
      }, {
        "type" : "STILL",
        "confidence" : 37
      } ]
    } ]
  }
...
  }, {
    "timestampMs" : "1556810257251",
    "latitudeE7" : 511051671,
    "longitudeE7" : 207460199,
    "accuracy" : 9,
    "velocity" : 0,
    "altitude" : 323,
    "verticalAccuracy" : 33
  } ]
}

如何为ExifTool命令格式化GPS坐标？
