我知道要找到两个纬度,经度点之间的距离我需要使用hasrsine函数:
def haversine(lon1, lat1, lon2, lat2):
lon1, lat1, lon2, lat2 = map(radians, [lon1, lat1, lon2, lat2])
dlon = lon2 - lon1
dlat = lat2 - lat1
a = sin(dlat/2)**2 + cos(lat1) * cos(lat2) * sin(dlon/2)**2
c = 2 * asin(sqrt(a))
km = 6367 * c
return km
我有一个DataFrame,其中一列是纬度,另一列是经度.我想知道这些点距离设定点有多远,-56.7213600,37.2175900.如何从DataFrame中获取值并将它们放入函数中？
示例DataFrame:

2 274.72, 56.8148320, 31.2923240
3 192.25, 52.0649880, 35.8018640
