百度地图API及几何运算开源库中“抽取”的对象及计算逻辑。
安装
$ npm install bmaplib
使用
var BMap = require('bmaplib').BMap;
var BMapLib = require('bmaplib').BMapLib;
var pts = [];
var pt1 = new BMap.Point(116.395, 39.910);
var pt2 = new BMap.Point(116.394, 39.914);
var pt3 = new BMap.Point(116.403, 39.920);
var pt4 = new BMap.Point(116.402, 39.914);
var pt5 = new BMap.Point(116.410, 39.913);
pts.push(pt1);
pts.push(pt2);
pts.push(pt3);
pts.push(pt4);
pts.push(pt5);
var ply = new BMap.Polygon(pts);
var pt =new BMap.Point(116.400, 39.914);
var result = BMapLib.GeoUtils.isPointInPolygon(pt, ply); //点在多边形内
var bp1 = new BMap.Point(114.23075520112,28.578514731829);
var bp2 = new BMap.Point(114.24063602435,29.579081890341);
var mid = new BMap.Point((bp1.lng+bp2.lng)/2,(bp1.lat+bp2.lat)/2);
console.log(BMapLib.GeoUtils.getDistance(bp1, bp2)); // 距离
var bounds1 = new BMap.Bounds(bp1, bp2); // Bounds
console.log(bounds1.getSouthWest());
console.log(BMapLib.GeoUtils.isPointInRect(mid, bounds1)); // 点在矩形内
// 另见demo.js
