多个纬度/经度点的半径 [英] Radius of multiple latitude/longitude points

问题描述

我有一个程序将纬度/经点数组作为输入.我需要对该数组进行检查，以确保所有点都在一定半径内.因此，例如，我允许的最大半径为100英里.给定一个经度/纬度数组(来自MySQL数据库，可能是10点可能是10000)，我需要弄清楚它们是否都适合半径100英里的圆.

I have a program that takes as input an array of lat/long points. I need to perform a check on that array to ensure that all of the points are within a certain radius. So, for example, the maximum radius I will allow is 100 miles. Given an array of lat/long (coming from a MySQL database, could be 10 points could be 10000) I need to figure out if they will all fit in a circle with radius of 100 miles.

Kinda苦恼于如何解决这个问题.任何帮助将不胜感激.

Kinda stumped on how to approach this. Any help would be greatly appreciated.
