直接和逆向大地测量问题。
该库使用简单的球形模型,而不是大地水准面甚至椭圆体。在这里,误差将在子午线全长的0.06%左右,在赤道半长的0.1%左右。在小段上误差更小,实际上适用于类似物流的任务。
需求
- php >= 7.1
通过 Composer 安装
composer require team-a/geo:^1.0.0
示例
<?php use TeamA\Geo; $Tver = Geo\Point::create(56.8598, 35.8948); $SouthPole = Geo\Point::create(-90.0, 0); $distance = ( new Geo\Line($Tver, $SouthPole) ) ->getDistance() ; $point2ToSouthPoleLine = Geo\Line::createByBearing($Tver, 90.0, 1000.0); $initialBearingToSouthPole = $point2ToSouthPoleLine->getInitialBearing(); $finalBearingToSouthPole = $point2ToSouthPoleLine->getFinalBearing(); $midPoint = $point2ToSouthPoleLine->getMidPoint();
