geo
Direct & inverse geodesic problems.
The library uses a simple spherical model, not a geoid or even an ellipsoid. The error here will be about 0.06% at full Meridian and about 0.1% at half equator. On smaller segments the error is much smaller and practically suitable for tasks similar to logistics.
Requirements
- php >= 7.1
Install via Composer
composer require team-a/geo:^1.0.0
Examples
<?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();
