Installation

It can be found on Packagist. The recommended way is through composer.

Edit compose.json and add:

{
    "require": {
        "toin0u/geotools-laravel": "~0.2"
    }
}

And install dependecies:

$ curl -sS https://getcomposer.org/installer | php
$ php composer.phar install

Usage

Registering GeotoolsServiceProvider is required.

<?php

use Geotools\Silex\GeotoolsServiceProvider;

// .. create $app
$app->register(new GeotoolsServiceProvider());

Examples

Coordinate & Ellipsoid

use League\Geotools\Coordinate\Ellipsoid;

$geotools = $app['geotools'];

// from an \Geocoder\Result\ResultInterface instance within Airy ellipsoid
$coordinate = $geotools->coordinate($geocoderResult, League\Geotools\Coordinate\Ellipsoid::createFromName(Ellipsoid::AIRY));
// or in an array of latitude/longitude coordinate within GRS 1980 ellipsoid
$coordinate = $geotools->coordinate(array(48.8234055, 2.3072664), League\Geotools\Coordinate\Ellipsoid::createFromName(Ellipsoid::GRS_1980));
// or in latitude/longitude coordinate within WGS84 ellipsoid
$coordinate = $geotools->coordinate('48.8234055, 2.3072664');
// or in degrees minutes seconds coordinate within WGS84 ellipsoid
$coordinate = $geotools->coordinate('48°49′24″N, 2°18′26″E');
// or in decimal minutes coordinate within WGS84 ellipsoid
$coordinate = $geotools->coordinate('48 49.4N, 2 18.43333E');
// the result will be:
printf("Latitude: %F\n", $coordinate->getLatitude()); // 48.8234055
printf("Longitude: %F\n", $coordinate->getLongitude()); // 2.3072664
printf("Ellipsoid name: %s\n", $coordinate->getEllipsoid()->getName()); // WGS 84
printf("Equatorial radius: %F\n", $coordinate->getEllipsoid()->getA()); // 6378136.0
printf("Polar distance: %F\n", $coordinate->getEllipsoid()->getB()); // 6356751.317598
printf("Inverse flattening: %F\n", $coordinate->getEllipsoid()->getInvF()); // 298.257224
printf("Mean radius: %F\n", $coordinate->getEllipsoid()->getArithmeticMeanRadius()); // 6371007.772533

Convert

$geotools = $app['geotools'];

$coordinate = $geotools->coordinate('40.446195, -79.948862');
$converted  = $geotools->convert($coordinate);
// convert to decimal degrees without and with format string
printf("%s\n", $converted->toDecimalMinutes()); // 40 26.7717N, -79 56.93172W
printf("%s\n", $converted->toDM('%P%D°%N %p%d°%n')); // 40°26.7717 -79°56.93172
// convert to degrees minutes seconds without and with format string
printf("%s\n", $converted->toDegreesMinutesSeconds('<p>%P%D:%M:%S, %p%d:%m:%s</p>')); // <p>40:26:46, -79:56:56</p>
printf("%s\n", $converted->toDMS()); // 40°26′46″N, 79°56′56″W
// convert in the UTM projection (standard format)
printf("%s\n", $converted->toUniversalTransverseMercator()); // 17T 589138 4477813
printf("%s\n", $converted->toUTM()); // 17T 589138 4477813 (alias)
