This is the PDOK (formerly Nationaal Georegister) provider for the PHP Geocoder, which uses the PDOK Locatieserver v3 (Dutch). It can geocode addresses (not IP addresses) and reverse geocode coordinates.

Please note that this provider can only (reverse) geocode addresses in The Netherlands!

Install

Via Composer

$ composer require swisnl/geocoder-php-nationaal-georegister-provider

HTTP Client

PHP Geocoder is decoupled from any HTTP messaging client with the help of PSR-18 HTTP Client. This requires another package providing psr/http-client-implementation. To use Guzzle 7, for example, simply require guzzlehttp/guzzle:

$ composer require guzzlehttp/guzzle

Usage

// Create geocoder
$client = new \GuzzleHttp\Client();
$geocoder = new \Swis\Geocoder\NationaalGeoregister\NationaalGeoregister($client);

// Geocode!
$query = \Geocoder\Query\GeocodeQuery::create(...);
$result = $geocoder->geocodeQuery($query);

Please see PHP Geocoder documentation for more information about using PHP Geocoder with this provider.

Options

This provider accepts extra options in the constructor, or as query data. These options are directly passed to the Locatieserver, which accepts the following options:

Option	Description	Default	Customizable in this provider
bq	Boost query	"type:gemeente^0.5 type:woonplaats^0.5 type:weg^1.0 type:postcode^1.5 type:adres^1.5"	yes
df	Default field	-	yes
fl	Field list	All fields used by this provider	no
fq	Filter query	-	yes
lat&lon	Latitude and longitude	Coordinates from \Geocoder\Query\ReverseQuery when reverse geocoding	only for geocoding
q	Search term	Text from \Geocoder\Query\GeocodeQuery when geocoding	no
rows	Amount of rows	Limit from query	no
start	Page (starting at 0)	-	yes
sort	Sorting	See Locatieserver documentation (Dutch)	yes
wt	Format	JSON	no

These options correspond with the options mentioned in the Locatieserver documentation (Dutch), which describes them in more detail.

Example using extra options:

// On the geocoder instance:
$client = new \GuzzleHttp\Client();
$options = ['fq' => 'bron:BAG'];
$geocoder = new \Swis\Geocoder\NationaalGeoregister\NationaalGeoregister($client, $options);

// Or just once on the query:
$query = \Geocoder\Query\GeocodeQuery::create(...)->withData('fq', 'bron:BAG');

Response

The geocoder returns a \Geocoder\Model\AddressCollection which is a collection of \Geocoder\Model\Address.

Example response (first \Geocoder\Model\Address from collection) for query "3e Binnenvestgracht 23T1, Leiden" using this provider:

$address->getCoordinates() => \Geocoder\Model\Coordinates
$address->getLatitude() => 52.164203
$address->getLongitude() => 4.49202289
$address->getBounds() => null (unavailable)
$address->getStreetNumber() => '23T-1'
$address->getStreetName() => '3e Binnenvestgracht'
$address->getPostalCode() => '2312NR'
$address->getLocality() => 'Leiden'
$address->getSubLocality() => null (unavailable)
$address->getAdminLevels()->get(2)->getName() => 'Leiden'
$address->getAdminLevels()->get(2)->getCode() => '0546'
$address->getAdminLevels()->get(1)->getName() => 'Zuid-Holland'
$address->getAdminLevels()->get(1)->getCode() => 'PV28'
$address->getCountry() => 'Netherlands' (static)
$address->getCountryCode() => 'NL' (static)
