Installation
------------

**Geotools** can be found on [Packagist](https://packagist.org/packages/league/geotools).
The recommended way to install **Geotools** is through [composer](http://getcomposer.org).

Run the following on the command line:

```
php composer require league/geotools=@stable
```

**Protip:** you should browse the
[`league/geotools`](https://packagist.org/packages/league/geotools)
page to choose a stable version to use, avoid the `@stable` meta constraint.

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

And install dependencies:

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

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

```php
<?php

require 'vendor/autoload.php';
```


Usage & API
-----------

## Coordinate & Ellipsoid ##

The default geodetic datum is [WGS84](http://en.wikipedia.org/wiki/World_Geodetic_System) 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
<?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](https://github.com/willdurand/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](http://en.wikipedia.org/wiki/Geographic_coordinate_conversion)
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
<?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
<?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
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)
```

Here is the mapping:

**Decimal minutes** | Latitude | Longitude
--- | --- | ---
Positive or negative sign | `%P` | `%p`
Direction | `%L` | `%l`
Degrees | `%D` | `%d`
Decimal minutes | `%N` | `%n`

**Degrees minutes seconds** | Latitude | Longitude
--- | --- | ---
Positive or negative sign | `%P` | `%p`
Direction | `%L` | `%l`
Degrees | `%D` | `%d`
Minutes | `%M` | `%m`
Seconds | `%S` | `%s`

## 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](https://github.com/willdurand/Geocoder) and [React](https://github.com/reactphp/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:
* **[Redis](http://redis.io/)**, [packagist](https://packagist.org/packages/predis/predis) and
[github](https://github.com/nrk/predis)
    * `Redis(array $client = [], $expire = 0)`
    * `$client` should be an array with `host`, `port` and `database` keys
    * `$expire` should be an integer, no expire value by default
    * `flush()` method deletes all the keys of the currently selected database which is `0` by default
* **[Memcached](http://memcached.org/)**, [php.net](http://fr.php.net/manual/fr/book.memcached.php)
    * `Memcached($server = self::DEFAULT_SERVER, $port = self::DEFAULT_PORT, $expire = 0)`
    * `$server` can be address like `example.com` or an IP, localhost is the default one
    * `$port` can be an integer like `11211` (by default)
    * `$expire` should be an integer, no expire value by default
    * `flush()` method invalidates all items in the cache
* **[MongoDB](http://www.mongodb.org/)**, [driver](http://docs.mongodb.org/ecosystem/drivers/php/) and
[php.net](http://us2.php.net/mongo)
    * `MongoDB($server = null, $database = self::DATABASE, $collection = self::COLLECTION)`
    * `$server` can be a string like `mongodb://example.com:65432`
    * `$database` can be a string like `geotools` (by default)
    * `$collection` can be a string like `geotools_cache` (by default)
    * `flush()` method drops the current collection

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
<?php

$geocoder = new \Geocoder\ProviderAggregator(); // or \Geocoder\TimedGeocoder
$adapter  = new \Ivory\HttpAdapter\CurlHttpAdapter();

$geocoder->registerProviders([
    new \Geocoder\Provider\GoogleMapsProvider($adapter),
    new \Geocoder\Provider\OpenStreetMapProvider($adapter),
    new \Geocoder\Provider\BingMapsProvider($adapter, '<FAKE_API_KEY>'), // throws InvalidCredentialsException
    new \Geocoder\Provider\YandexProvider($adapter),
    new \Geocoder\Provider\FreeGeoIpProvider($adapter),
    new \Geocoder\Provider\GeoipProvider(),
]);

try {
    $geotools = new \League\Geotools\Geotools();
    $cache    = new \League\Geotools\Cache\MongoDB();
    // or
    $cache    = new \League\Geotools\Cache\Redis([
        'host'     => '127.0.0.1',
        'port'     => 6379,
        'database' => 15 // the last database ID
    ]);
    $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
<?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](https://github.com/willdurand/Geocoder#freegeoipprovider).

## 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
<?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
<?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
<?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
```

## 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](http://blog.jgc.org/2006/07/simple-code-for-entering-latitude-and.html).

```php
<?php

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

## 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
<?php

$polygon = new \League\Geotools\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

Compute street addresses, IPv4s or IPv6s geocoding and reverse geocoding right in your console.

It's possible to define and precise your request through these options:
* `--adapter`: `socket`, `buzz`, `zend`, `guzzle` or `curl` by default.
* `--provider`: `bing_maps`, `yahoo`, `maxmind`... `google_maps` is the default one. See the full list
[here](https://github.com/willdurand/Geocoder#providers).
* `--cache`: `mongodb`, `memcached` or `redis` as a fallback.
* `--raw`: the result output in RAW format, shows Adapter, Provider and Arguments if any.
* `--json`: the result output in JSON string format.
* `--args`: this option accepts multiple values (e.g. --args="API_KEY" --args="LOCALE") if your provider needs or
can have arguments.
* `--dumper`: this option is available for geocoding, `gpx`, `geojson`, `kml`, `wkb` and `wkt` by default.
Read more [here](https://github.com/willdurand/Geocoder#dumpers).
* `--format`: this option is available for reverse geocoding, see the mapping
[here](https://github.com/willdurand/Geocoder#formatter).

```bash
$ php geotools help geocoder:geocode // get the help
$ php geotools geocoder:geocode "Copenhagen, Denmark" // 55.6760968, 12.5683371
$ php geotools geocoder:geocode "74.200.247.59" --provider="free_geo_ip" --adapter="socket" // 37.7484, -122.4156
$ php geotools geocoder:geocode Paris --args="fr_FR" --args="France" --args="true" // 48.856614, 2.3522219
$ php geotools geocoder:geocode Paris --dumper=wkt // POINT(2.352222 48.856614)
...
$ php geotools geocoder:reverse "48.8631507, 2.388911" // Avenue Gambetta 10, 75020 Paris
$ php geotools geocoder:reverse "48.8631507, 2.388911" --format="%L, %R, %C" // Paris, Île-De-France, France
$ php geotools geocoder:reverse "48.8631507, 2.388911" --format="%L, %R, %C" --provider="openstreetmaps"
// Paris, Île-De-France, France Métropolitaine
...
$ php geotools geocoder:geocode "Tagensvej 47, Copenhagen" --raw --args=da_DK --args=Denmark --adapter=socket --cache=redis
```

The last command will show an output like this:

```
Adapter:       \Ivory\HttpAdapter\SocketHttpAdapter
Provider:      \Geocoder\Provider\GoogleMaps
Cache:         \League\Geotools\Cache\Redis
Arguments:     da_DK,Denmark
