Geocoding is the geolocation of addresses in Spain via Cartociudad API calls. Calling the geocode function returns the details of the closest address in Spain to the indicated address.

import pycartociudad as pycc pycc.geocode('Plaza mayor 1, madrid')

Returns:

{

"id":"280790001063", "province":"Madrid", "comunidadAutonoma":"Comunidad de Madrid", "muni":"Madrid", "type":"portal", "address":"MAYOR", "postalCode":"28012", "poblacion":"Madrid", "geom":"POINT (-3.7066353973101624 40.41505683353346)", "tip_via":"PLAZA", "lat":40.41505683353346, "lng":-3.7066353973101624, "portalNumber":1, "stateMsg":"Resultado exacto de la búsqueda", "state":1, "countryCode":"011", "refCatastral":"None"

}

Reverse geocoding

Reverse geocoding is the search of an address details based on latitude and longitude coordinates.

import pycartociudad as pycc pycc.reverse_geocode(40.4472, -3.7076)

Returns:

{

"id":"280790165933", "province":"Madrid", "comunidadAutonoma":"Comunidad de Madrid", "muni":"Madrid", "type":"None", "address":"REINA VICTORIA", "postalCode":"28003", "poblacion":"Madrid", "geom":"POINT (-3.707649842620833 40.447247624136764)", "tip_via":"AVENIDA", "lat":40.447247624136764, "lng":-3.707649842620833, "portalNumber":22, "stateMsg":"Resultado exacto de la búsqueda", "state":1, "priority":0, "countryCode":"011", "refCatastral":"None"

}

Reverse geocoding can be performed to look for cadastral details with the cadastral parameter.

pycc.reverse_geocode(40.4472476241486,-3.7076498426208833, cadastral=True)

Returns:

{

"id":"None", "province":"None", "comunidadAutonoma":"None", "muni":"None", "type":"None", "address":"0079609VK4707G", "postalCode":"None", "poblacion":"None", "geom":"POINT (-3.7076498426208833 40.4472476241486)", "tip_via":"None", "lat":40.4472476241486, "lng":-3.7076498426208833, "portalNumber":0, "stateMsg":"Resultado exacto de la búsqueda", "state":1, "priority":0, "countryCode":"011", "refCatastral":"AV REINA VICTORIA 22 MADRID (MADRID)"

}

Get location info

The get_location_info function gets extra information of a location using official spanish web map services, such as cadastre, census or geocoding information.

import pycartociudad as pycc pycc.get_location_info(40.4472476241486,-3.7076498426208833)

Returns:

{

"cadastral_ref":"0079609VK4707G", "census_section":"2807906001", "district_code":"2807906", "id":"280790165933", "province":"Madrid", "comunidadAutonoma":"Comunidad de Madrid", "muni":"Madrid", "type":"None", "address":"REINA VICTORIA", "postalCode":"28003", "poblacion":"Madrid", "geom":"POINT (-3.707649842620833 40.447247624136764)", "tip_via":"AVENIDA", "lat":40.447247624136764, "lng":-3.707649842620833, "portalNumber":22, "stateMsg":"Resultado exacto de la búsqueda", "state":1, "priority":0, "countryCode":"011", "refCatastral":"None"

}

Route between two points

This function gets the route between two points (encoded with their latitude-longitude coordinates), either walking or in a vehicle.

import pycartociudad as pycc d = pycc.route_between_two_points(40.447313139920475,-3.704361232340851,40.44204376380937,-3.699671450323607) for i in d['instructionsData']['instruction']:

print(i['description'])

Prints:

Continúe por GLORIETA CUATRO CAMINOS Gire justo a la derecha por CALLE SANTA ENGRACIA Gire a la izquierda por CALLE RIOS ROSAS Objetivo logrado

Get static map image

This function gets a static map centered on an address, as a png image.

Please note this function is quite heavy on the server side, it should be used only for single uses. For an extensive use, please consider cached map tiles extraction (for an example on this use, please check the example_get_map in the notebooks directory.

Running the tests

To run a subset of tests:

$ python -m unittest tests.test_geocode
$ python -m unittest tests.test_reverse_geocode
