我想根据纬度和经度从Google地球获取高程数据,但我无法做到这一点.我不确定我做错了什么,但我的代码如下所示.

def getElevation(locations,sensor="true", **elvtn_args):
    elvtn_args.update({
        'locations': locations,
        'sensor': sensor
    })

    url = ELEVATION_BASE_URL
    params =  urllib.parse.urlencode(elvtn_args)
    baseurl = url +"?"+ params;
    req = urllib.request.urlopen(str(baseurl));
    response = simplejson.load(req);

而我得到的错误是:

Traceback (most recent call last):

    getElevation(pathStr)
  File "D:\GIS\Arctools\ElevationChart - Copy.py", line 45, in getElevation
