Look up information about Icelandic street addresses and postcodes

Project description

iceaddr

Build Status

Look up Icelandic street addresses and postcodes

Python (2 and 3) module to look up and get information about Icelandic street addresses and postcodes. The underlying data is taken from Staðfangaskrá, the official Icelandic Address Registry maintained by Registers Iceland (CC-BY), IS 50V Örnefni from the National Land Survey of Iceland, and from the postcode table provided by Postur.is.

Installation

$ pip install iceaddr

Examples

Look up address with postcode:

>>> from iceaddr import iceaddr_lookup
>>> a = iceaddr_lookup('Austurstræti', number=14, postcode=101)
>>> pprint.pprint(a)
[{'bokst': '',
  'byggd': 1,
  'heiti_nf': 'Austurstræti',
  'heiti_tgf': 'Austurstræti',
  'hnitnum': 10083839,
  'husnr': 14,
  'landnr': 100852,
  'lat_wgs84': 64.147529217656,
  'long_wgs84': -21.9389394651385,
  'postnr': 101,
  'serheiti': '',
  'stadur_nf': 'Reykjavík',
  'stadur_tgf': 'Reykjavík',
  'svaedi': 'Höfuðborgarsvæðið',
  'svfnr': 0,
  'tegund': 'Þéttbýli',
  'vidsk': '',
  'x_isn93': 356999.259090909,
  'y_isn93': 408290.561363636}]

Look up address with place name

>>> from iceaddr import iceaddr_lookup
>>> a = iceaddr_lookup('Öldugötu', number=4, placename='Reykjavík')
>>> pprint.pprint(a)
[{'bokst': '',
  'byggd': 1,
  'heiti_nf': 'Öldugata',
  'heiti_tgf': 'Öldugötu',
  'hnitnum': 10017023,
  'husnr': 4,
  'landnr': 100570,
  'lat_wgs84': 64.1484874806941,
  'long_wgs84': -21.9452072913341,
  'postnr': 101,
  'serheiti': '',
  'stadur_nf': 'Reykjavík',
  'stadur_tgf': 'Reykjavík',
  'svaedi': 'Höfuðborgarsvæðið',
  'svfnr': 0,
  'tegund': 'Þéttbýli',
  'vidsk': '',
  'x_isn93': 356699.479545455,
  'y_isn93': 408411.468181818}]

Street and place names can be provided in either nominative or dative case (e.g. both 'Öldugata' and 'Öldugötu' will work, as will both 'Selfoss' and 'Selfossi').

Please note thaticeaddr_lookup() returns a list of zero or more addresses matching the criterion.

>>> from iceaddr import iceaddr_lookup
>>> iceaddr_lookup('Dúfnahólar', number=10)
[]
>>> res = iceaddr_lookup('Öldugata', number=9)
>>> [(a['postnr'], a['stadur_nf']) for a in res]
[(101, 'Reykjavík'), (220, 'Hafnarfjörður'), (621, 'Dalvík')]

For natural search string queries, the module provides iceaddr_suggest():

>>> from iceaddr import iceaddr_suggest
>>>
>>> a = iceaddr_suggest('Öldugata 4, Rey')
>>> [n['stadur_tgf'] for n in a]
['Reykjavík', 'Reyðarfirði']
>>> a = iceaddr_suggest('Öldugö', limit=200)
>>> len(a)
151

The default limit on results from both functions is 50.

Postcodes

>>> from iceaddr import postcodes_for_placename
>>> postcodes_for_placename('Ísafjörður')
[400, 401]
>>> postcodes_for_placename('Kópavogi')
[200, 201, 202, 203]
>>> postcodes_for_placename('kópav', partial=True)
[200, 201, 202, 203]
>>>
>>> from iceaddr import postcodes
>>> postcodes.get(400)
{   'svaedi': 'Vesturland og Vestfirðir', 
    'stadur_nf': 'Ísafjörður', 
    'stadur_tgf': 'Ísafirði', 
    'tegund': 'Þéttbýli' }

Placenames ("örnefni")

>>> from iceaddr import placename_lookup
>>> placename_lookup('Meðalfellsvatn')
[{'flokkur': 'Vatnaörnefni Mið',
  'id': 2339,
  'lat_wgs84': 64.3112049,
  'long_wgs84': -21.5997926,
  'nafn': 'Meðalfellsvatn'}]

If more than one placename match is found, the results are ordered by size, with precedence given to municipalities and densely populated areas.
