使用geopy.distance.great_circle函数来计算两个坐标之间的距离。 city1_coords和city2_coords是城市的经纬度,它们应该以元组的格式传递。 4. 使用函数计算距离 现在我们将定义一些城市的经纬度,并使用定义的函数来计算它们之间的距离。 # 定义城市的经纬度city1=(40.7128,-74.0060)# New York Citycity2=(34.0522,...

d=distance.great_circle(old, new).m s=round(float(d),2) return s 效率如下: 使用上述第二种代码测试,计算一次为94.9us,计算出距离为1674243.53。 2、大圆距离 大圆距离使用地球圆形模型,先将经纬度转换为弧度,然后把地球当作一个6371的圆来计算球面距离。
