Installation

Geotools can be found on Packagist. The recommended way to install Geotools is through composer.

Run the following on the command line:

composer require league/geotools

Important: you should use the 0.4 version if you use Geocoder 2.x or/and PHP 5.3.

And install dependencies:

composer install

Now you can add the autoloader, and you will have access to the library:

<?php

require 'vendor/autoload.php';

Usage & API

Coordinate & Ellipsoid

The default geodetic datum is WGS84 and coordinates are in decimal degrees.

Here are the available ellipsoids: AIRY, AUSTRALIAN_NATIONAL, BESSEL_1841, BESSEL_1841_NAMBIA, CLARKE_1866, CLARKE_1880, EVEREST, FISCHER_1960_MERCURY, FISCHER_1968, GRS_1967, GRS_1980, HELMERT_1906, HOUGH, INTERNATIONAL, KRASSOVSKY, MODIFIED_AIRY, MODIFIED_EVEREST, MODIFIED_FISCHER_1960, SOUTH_AMERICAN_1969, WGS60, WGS66, WGS72, and WGS84.

If you need to use an other ellipsoid, just create an array like this:

<?php

$myEllipsoid = \League\Geotools\Coordinate\Ellipsoid::createFromArray([
    'name' => 'My Ellipsoid', // The name of the Ellipsoid
    'a'    => 123.0, // The semi-major axis (equatorial radius) in meters
    'invF' => 456.0 // The inverse flattening
]);

Geotools is built atop Geocoder. It means it's possible to use the \Geocoder\Model\Address directly but it's also possible to use a string or a simple array with its latitude and longitude.

It supports valid and acceptable geographic coordinates like:

  • 40:26:46N,079:56:55W
  • 40:26:46.302N 079:56:55.903W
  • 40°26′47″N 079°58′36″W
  • 40d 26′ 47″ N 079d 58′ 36″ W
  • 40.446195N 79.948862W
  • 40.446195, -79.948862
  • 40° 26.7717, -79° 56.93172

Latitudes below -90.0 or above 90.0 degrees are capped through \League\Geotools\Coordinate\Coordinate::normalizeLatitude(). Longitudes below -180.0 or above 180.0 degrees are wrapped through \League\Geotools\Coordinate\Coordinate::normalizeLongitude().

<?php

use League\Geotools\Coordinate\Coordinate;
use League\Geotools\Coordinate\Ellipsoid;

// from an \Geocoder\Model\Address instance within Airy ellipsoid
$coordinate = new Coordinate($geocoderResult, Ellipsoid::createFromName(Ellipsoid::AIRY));
// or in an array of latitude/longitude coordinate within GRS 1980 ellipsoid
$coordinate = new Coordinate([48.8234055, 2.3072664], Ellipsoid::createFromName(Ellipsoid::GRS_1980));
// or in latitude/longitude coordinate within WGS84 ellipsoid
$coordinate = new Coordinate('48.8234055, 2.3072664');
// or in degrees minutes seconds coordinate within WGS84 ellipsoid
$coordinate = new Coordinate('48°49′24″N, 2°18′26″E');
// or in decimal minutes coordinate within WGS84 ellipsoid
$coordinate = new 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
// it's also possible to modify the coordinate without creating an other coodinate
$coordinate->setFromString('40°26′47″N 079°58′36″W');
printf("Latitude: %F\n", $coordinate->getLatitude()); // 40.446388888889
printf("Longitude: %F\n", $coordinate->getLongitude()); // -79.976666666667

Convert

It provides methods (and aliases) to convert decimal degrees WGS84 coordinates to degrees minutes seconds or decimal minutes WGS84 coordinates. You can format the output string easily.

You can also convert them in the Universal Transverse Mercator (UTM) projection (Southwest coast of Norway and the region of Svalbard are covered).

<?php

$geotools   = new \League\Geotools\Geotools();
$coordinate = new \League\Geotools\Coordinate\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
// 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>
// convert in the UTM projection (standard format)
printf("%s\n", $converted->toUniversalTransverseMercator()); // 17T 589138 4477813

Here is the mapping:

Batch

It provides a very handy way to batch geocode and reverse geocoding requests in serie or in parallel against a set of providers. Thanks to Geocoder and React libraries.

It's possible to batch one request (a string) or a set of request (an array) against one provider or set of providers.

You can use a provided cache engine or use your own by setting a cache object which should implement League\Geotools\Cache\CacheInterface and extend League\Geotools\Cache\AbstractCache if needed.

At the moment Geotools supports any PSR-6 cache.

NB: Before you implement caching in your app please be sure that doing so does not violate the Terms of Service for your(s) geocoding provider(s).

<?php

$geocoder = new \Geocoder\ProviderAggregator(); // or \Geocoder\TimedGeocoder
$httpClient  = HttpClientDiscovery::find();

$geocoder->registerProviders([
    new \Geocoder\Provider\GoogleMaps\GoogleMaps($httpClient),
    new \Geocoder\Provider\OpenStreetMap\OpenStreetMap($httpClient),
    new \Geocoder\Provider\BingMaps\BingMaps($httpClient, '<FAKE_API_KEY>'), // throws InvalidCredentialsException
    new \Geocoder\Provider\Yandex\Yandex($httpClient),
    new \Geocoder\Provider\FreeGeoIp\FreeGeoIp($httpClient),
    new \Geocoder\Provider\Geoip\Geoip(),
]);

try {
    $geotools = new \League\Geotools\Geotools();
    $cache    = new \Cache\Adapter\PHPArray\ArrayCachePool();

    $results  = $geotools->batch($geocoder)->setCache($cache)->geocode([
        'Paris, France',
        'Copenhagen, Denmark',
        '74.200.247.59',
        '::ffff:66.147.244.214'
    ])->parallel();
} catch (\Exception $e) {
    die($e->getMessage());
}

$dumper = new \Geocoder\Dumper\WktDumper();
foreach ($results as $result) {
    // if a provider throws an exception (UnsupportedException, InvalidCredentialsException ...)
    // an custom /Geocoder/Result/Geocoded instance is returned which embedded the name of the provider,
    // the query string and the exception string. It's possible to use dumpers
    // and/or formatters from the Geocoder library.
    printf("%s|%s|%s\n",
        $result->getProviderName(),
        $result->getQuery(),
        '' == $result->getExceptionMessage() ? $dumper->dump($result) : $result->getExceptionMessage()
    );
}

You should get 24 results (4 values to geocode against 6 providers) something like:

Batch reverse geocoding is something like:

<?php

// ... $geocoder like the previous example ...
// If you want to reverse one coordinate
try {
    $results = $geotools->batch($geocoder)->reverse(
        new \League\Geotools\Coordinate\Coordinate([2.307266, 48.823405])
    )->parallel();
} catch (\Exception $e) {
    die($e->getMessage());
}
// Or if you want to reverse geocoding 3 coordinates
$coordinates = [
    new \League\Geotools\Coordinate\Coordinate([2.307266, 48.823405]),
    new \League\Geotools\Coordinate\Coordinate([12.568337, 55.676097]),
    new \League\Geotools\Coordinate\Coordinate('-74.005973 40.714353')),
];
$results = $geotools->batch($geocoder)->reverse($coordinates)->parallel();
// ...

If you want to batch it in serie, replace the method parallel() by serie().

To optimize batch requests you need to register providers according to their capabilities and what you're looking for (geocode street addresses, geocode IPv4, geocode IPv6 or reverse geocoding), please read more at the Geocoder library doc.

Distance

It provides methods to compute the distance in meter (by default), km, mi or ft between two coordinates using flat (most performant), great circle, haversine or vincenty (most accurate) algorithms.

Those coordinates should be in the same ellipsoid.

<?php

$geotools = new \League\Geotools\Geotools();
$coordA   = new \League\Geotools\Coordinate\Coordinate([48.8234055, 2.3072664]);
$coordB   = new \League\Geotools\Coordinate\Coordinate([43.296482, 5.36978]);
$distance = $geotools->distance()->setFrom($coordA)->setTo($coordB);

printf("%s\n",$distance->flat()); // 659166.50038742 (meters)
printf("%s\n",$distance->greatCircle()); // 659021.90812846
printf("%s\n",$distance->in('km')->haversine()); // 659.02190812846
printf("%s\n",$distance->in('mi')->vincenty()); // 409.05330679648
printf("%s\n",$distance->in('ft')->flat()); // 2162619.7519272

Point

It provides methods to compute the initial and final bearing in degrees, the initial and final cardinal direction, the middle point and the destination point. The middle and the destination points returns a \League\Geotools\Coordinate\Coordinate object with the same ellipsoid.

<?php

$geotools = new \League\Geotools\Geotools();
$coordA   = new \League\Geotools\Coordinate\Coordinate([48.8234055, 2.3072664]);
$coordB   = new \League\Geotools\Coordinate\Coordinate([43.296482, 5.36978]);
$vertex    =  $geotools->vertex()->setFrom($coordA)->setTo($coordB);

printf("%d\n", $vertex->initialBearing()); // 157 (degrees)
printf("%s\n", $vertex->initialCardinal()); // SSE (SouthSouthEast)
printf("%d\n", $vertex->finalBearing()); // 160 (degrees)
printf("%s\n", $vertex->finalCardinal()); // SSE (SouthSouthEast)

$middlePoint = $vertex->middle(); // \League\Geotools\Coordinate\Coordinate
printf("%s\n", $middlePoint->getLatitude()); // 46.070143125815
printf("%s\n", $middlePoint->getLongitude()); // 3.9152401085931

$destinationPoint = $geotools->vertex()->setFrom($coordA)->destination(180, 200000); // \League\Geotools\Coordinate\Coordinate
printf("%s\n", $destinationPoint->getLatitude()); // 47.026774650075
printf("%s\n", $destinationPoint->getLongitude()); // 2.3072664

Geohash

It provides methods to get the geo hash and its bounding box's coordinates (SouthWest & NorthEast) of a coordinate and the coordinate and its bounding box's coordinates (SouthWest & NorthEast) of a geo hash.

<?php

$geotools       = new \League\Geotools\Geotools();
$coordToGeohash = new \League\Geotools\Coordinate\Coordinate('43.296482, 5.36978');

// encoding
$encoded = $geotools->geohash()->encode($coordToGeohash, 4); // 12 is the default length / precision
// encoded
printf("%s\n", $encoded->getGeohash()); // spey
// encoded bounding box
$boundingBox = $encoded->getBoundingBox(); // array of \League\Geotools\Coordinate\CoordinateInterface
$southWest   = $boundingBox[0];
$northEast   = $boundingBox[1];
printf("http://www.openstreetmap.org/?minlon=%s&minlat=%s&maxlon=%s&maxlat=%s&box=yes\n",
    $southWest->getLongitude(), $southWest->getLatitude(),
    $northEast->getLongitude(), $northEast->getLatitude()
); // http://www.openstreetmap.org/?minlon=5.2734375&minlat=43.2421875&maxlon=5.625&maxlat=43.41796875&box=yes

// decoding
$decoded = $geotools->geohash()->decode('spey61y');
// decoded coordinate
printf("%s\n", $decoded->getCoordinate()->getLatitude()); // 43.296432495117
printf("%s\n", $decoded->getCoordinate()->getLongitude()); // 5.3702545166016
// decoded bounding box
$boundingBox = $decoded->getBoundingBox(); //array of \League\Geotools\Coordinate\CoordinateInterface
$southWest   = $boundingBox[0];
$northEast   = $boundingBox[1];
printf("http://www.openstreetmap.org/?minlon=%s&minlat=%s&maxlon=%s&maxlat=%s&box=yes\n",
    $southWest->getLongitude(), $southWest->getLatitude(),
    $northEast->getLongitude(), $northEast->getLatitude()
); // http://www.openstreetmap.org/?minlon=5.3695678710938&minlat=43.295745849609&maxlon=5.3709411621094&maxlat=43.297119140625&box=yes

You can also get information about neighbor points (image).

<?php

$geotools = new \League\Geotools\Geotools();

// decoding
$decoded = $geotools->geohash()->decode('spey61y');
// get neighbor geohash
printf("%s\n", $decoded->getNeighbor(\League\Geotools\Geohash\Geohash::DIRECTION_NORTH)); // spey64n
printf("%s\n", $decoded->getNeighbor(\League\Geotools\Geohash\Geohash::DIRECTION_SOUTH_EAST)); // spey61x
// get all neighbor geohashes
print_r($decoded->getNeighbors(true));
/**
 * Array
 * (
 *     [north] => spey64n
 *     [south] => spey61w
 *     [west] => spey61v
 *     [east] => spey61z
 *     [north_west] => spey64j
 *     [north_east] => spey64p
 *     [south_west] => spey61t
 *     [south_east] => spey61x
 * )
 */

10:10

Represent a location with 10m accuracy using a 10 character code that includes features to prevent errors in entering the code. Read more about the algorithm here.

<?php

$tenten = new \League\Geotools\Tests\Geohash\TenTen;
$tenten->encode(new Coordinate([51.09559, 1.12207])); // MEQ N6G 7NY5

Vertex

Represents a segment with a direction. You can find if two vertexes are on the same line.

<?php
	$vertexA->setFrom(48.8234055);
	$vertexA->setTo(2.3072664);

	$vertexB->setFrom(48.8234055);
	$vertexB->setTo(2.3072664);
	$vertexA->isOnSameLine($vertexB);

Polygon

It helps you to know if a point (coordinate) is in a Polygon or on the Polygon's boundaries and if this in on a Polygon's vertex.

First you need to create the polygon, you can provide:

  • an array of arrays
  • an array of Coordinate
  • a CoordinateCollection
<?php

$polygon = new \League\Geotools\Polygon\Polygon([
    [48.9675969, 1.7440796],
    [48.4711003, 2.5268555],
    [48.9279131, 3.1448364],
    [49.3895245, 2.6119995],
]);

$polygon->setPrecision(5); // set the comparision precision
$polygon->pointInPolygon(new \League\Geotools\Coordinate\Coordinate([49.1785607, 2.4444580])); // true
$polygon->pointInPolygon(new \League\Geotools\Coordinate\Coordinate([49.1785607, 5])); // false
$polygon->pointOnBoundary(new \League\Geotools\Coordinate\Coordinate([48.7193486, 2.13546755])); // true
$polygon->pointOnBoundary(new \League\Geotools\Coordinate\Coordinate([47.1587188, 2.87841795])); // false
$polygon->pointOnVertex(new \League\Geotools\Coordinate\Coordinate([48.4711003, 2.5268555])); // true
$polygon->pointOnVertex(new \League\Geotools\Coordinate\Coordinate([49.1785607, 2.4444580])); // false
$polygon->getBoundingBox(); // return the BoundingBox object

CLI

It provides command lines to compute methods provided by Distance, Point, Geohash and Convert classes. Thanks to the Symfony Console Component.
