我有一个包含位置列的数据框,其中包含纬度,长位置,如下所示
deviceid location
1102ADb75 [12.9404578177, 77.5548244743]
如何使用geopy的副功能获取连续行之间的距离? 我尝试了以下代码
from geopy.distance import vincenty
vincenty(df['location'].shift(-1), df['location']).miles
它返回以下错误 - TypeError:__ new __()最多需要4个参数(给定5个)
编辑 - 其中df是包含deviceId&amp ;;的Pandas数据帧。位置列如上所示 还
print type(df)
class 'pandas.core.frame.DataFrame'
答案 0 :(得分:2)
基于geopy's github,你应该将两个元组传递给vincenty
函数:
>>> from geopy.distance import vincenty
>>> point_a = (41.49008, -71.312796)
>>> point_b = (41.499498, -81.695391)
>>> print(vincenty(point_a, point_b).miles)
538.3904451566326
修改强>:
import pandas as pd
from geopy.distance import vincenty
data = [[101, [41.49008, -71.312796]],
[202, [41.499498, -81.695391]]]
df = pd.DataFrame(data=data, columns=['deviceid', 'location'])
print df
>>> deviceid location
>>> 0 101 [41.49008, -71.312796]
>>> 1 202 [41.499498, -81.695391]
print vincenty(df['location'][0], df['location'][1]).miles
>>> 538.390445157
