README

  • 可扩展任意椭球体计算：需实现 Circle 接口；
  • 可扩展任意椭球体坐标系转换：需继承 Geography 抽象类；
  • 可扩展任意椭球体计算方法：默认只支持两坐标距离计算，可扩展实现三角形、正方形、长方形、梯形面积计算；
  • 可扩展计算单位：默认支持长度单位，可扩展面积单位，需实现 Units 接口；
  • 可扩展任意地理坐标系：北京 54、西安 80、 WGS84、GCJ-02、BD-09、GCS2000
  • 可扩展任意语言：默认支持中文英文，可自定义其他语言；

$points    = [
    [116.4028930664, 39.9034155951],

计算两坐标间距离

$position = new Position();
$position->setDecimals(2);
// 标准坐标计算距离
$distance = $position->getDistance(
    new Point(116.4028930664, 39.9034155951),
    new Point(114.3347167969, 30.5433389542)
);
// 结果：1058703.49
// 其他格式标准计算距离
$distance = $position->getDistance(
    new Converter("东经98度58分45.8秒", "南纬24度45分16.1秒"),
    new Converter("116°23′28.4″E", "39°54′26.2″N")
);
// 结果：7421559.99

计算两坐标间距离（附加单位）

$position = new Position(new LengthUnit("KM"));
$position->setDecimals(2);
// 标准坐标计算距离
$distance = $position->getDistanceUnit(
    new Point(116.4028930664, 39.9034155951),
    new Point(114.3347167969, 30.5433389542)
