Project description

iceaddr

Build Status

Look up Icelandic street addresses, postcodes and placenames

iceaddr is a Python 3.x package to look up information about Icelandic streets, addresses, placenames, landmarks, locations and postcodes. The underlying data is assembled from the following sources:

Installation

iceaddr is available on PyPI.

$ pip install iceaddr

Examples

Look up address with postcode

>>> from iceaddr import iceaddr_lookup
>>> a = iceaddr_lookup('Austurstræti', number=14, postcode=101)
>>> 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_nf': 'Höfuðborgarsvæðið',
  'svaedi_tgf': 'Höfuðborgarsvæðinu',
  'svfnr': 0,
  'tegund': 'Þéttbýli',
  'vidsk': '',
  'x_isn93': 356999.259090909,
  'y_isn93': 408290.561363636}]

Look up address with placename

>>> from iceaddr import iceaddr_lookup
>>> a = iceaddr_lookup('Öldugötu', number=4, placename='Reykjavík')
>>> 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_nf': 'Höfuðborgarsvæðið',
  'svaedi_tgf': 'Höfuðborgarsvæðinu',
  'svfnr': 0,
  'tegund': 'Þéttbýli',
  'vidsk': '',
  'x_isn93': 356699.479545455,
  'y_isn93': 408411.468181818}]

Street and place names can be provided in either nominative (nf.) or dative (þgf.) 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.

>>> postcode_lookup(400)
{   "svaedi_nf": "Vesturland og Vestfirðir",
    "svaedi_tgf": "Vesturlandi og Vestfjörðum",
    "stadur_nf": "Ísafjörður", 
    "stadur_tgf": "Ísafirði", 
    "tegund": "Þéttbýli" }
# Accepts string or int
>>> postcode_lookup("107")
{   "svaedi_nf": "Höfuðborgarsvæðið",
    "svaedi_tgf": "Höfuðborgarsvæðinu",
    "stadur_nf": "Reykjavík",
    "stadur_tgf": "Reykjavík",

    "stadur_nf": "Reykjavík",
    "stadur_tgf": "Reykjavík",
    "tegund": "Þéttbýli",
    "lysing": "Miðborg" }

Get postcodes for a placename

>>> 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]
>>>

Get postcodes for a region

>>> from iceaddr import postcodes_for_region
>>> postcodes_for_region('Norðurland')
[530, 531, 540, 541, 545, ...]
>>> postcodes_for_region('Höfuðborgarsvæðið')
[101, 102, 103, 104, 105, ...]
>>>

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.

>>> placename_lookup("Egilsstað", partial=True)
[{'flokkur': 'Þéttbýli',
  'id': 63208,
  'lat_wgs84': 65.2637152,
  'long_wgs84': -14.3931143,
  'nafn': 'Egilsstaðir'},
 {'flokkur': 'Landörnefni Lítið',
  'id': 108285,
  'lat_wgs84': 65.3516154,
  'long_wgs84': -20.610947,
  'nafn': 'Egilsstaðir'}]
