只要不超过以上范围

本函数旨在实现图像中求两点之间的距离
function [dist,phaseangle] = distance(lat,lon,units)
% SW_DIST Distance between two lat,lon coordinates

% SW_DIST $Revision: 1.4 $ $Date: 1994/10/10 04:55:23 $
% Copyright (C) CSIRO, Phil Morgan & Steve Rintoul 1992.
%
% USAGE: [dist,phaseangle] = distance(lat,lon {,units} )
%
% DESCRIPTION:
% Calculate distance between two positions on glode using the "Plane
% Sailing" method. Also uses simple geometry to calculate the bearing of
% the path between position pairs.
%
% INPUT:
% lat = decimal degrees (+ve N, -ve S) [- 90.. +90]
% lon = decimal degrees (+ve E, -ve W) [-180..+180]
% units = optional string specifing units of distance
% 'nm' = nautical miles (default)
% 'km' = kilometres
%
% OUTPUT:
% dist = distance between positions in units
% phaseangle = angle of line between stations with x axis (East).
% Range of values are -180..+180. (E=0, N=90, S=-90)

Swift 使用mapkit 实现在地图上两点（多点）画线，画多条·多种颜色的线
最终效果图：
首先新建一个项目（可选）
在storyboard中新建一个ViewController视图
然后新建一个UIViewController的之类并且在storyboard中和ViewController视图进行绑定：
在视图中，从视图库添加一个MKMapview到视图中。然后拉扯到你想要的大小，设定约束，可以使用约束让它涨满整个view
打开 assitant 窗口，按住ctrl+鼠标左键，拖拽MKMapview带代码区域： @IBOutlet var mapView: MKMapView!

在网上找个好几种方法来根据经纬度算距离和方位角，但误差都比较多，这个是我个人优化的，通过测试误差比较像小，希望能帮到大家
