country-bounding-boxes 0.2.3

Library of bounding boxes of countries (and associated data)

Contains the bounding boxes and miscallaneous additional information for countries extracted from

http://www.naturalearthdata.com/

Note that many countries have a number of “subunits”: geographically disjoint components like Alaska in the USA, administratively distinct regions such as the countries of Great Britain, or overseas islands for many European nations. As a result this module returns iterators over sets of Country objects for each country code, rather than single Country objects.

Previous versions of this library returned an (often large) singular bounding box for each country code; in many cases these spanned much of the globe and were therefore geographically less useful.

Installation

$ pip install country-bounding-boxes

Usage

>>> from country_bounding_boxes import (
      country_subunits_containing_point,
      country_subunits_by_iso_code
    )

Get a country by its 2- or 3-letter ISO code:

>>> [c.name for c in country_subunits_by_iso_code('ZW')]
['Zimbabwe']

>>> [c.name for c in country_subunits_by_iso_code('ZWE')]
['Zimbabwe']

>>> [c.name for c in country_subunits_by_iso_code('TM')]
['Turkmenistan']

>>> [c.name for c in country_subunits_by_iso_code('GB')]
['Wales', 'England', 'N. Ireland', 'Scotland']

Inspect bounding box as (lon1, lat1, lon2, lat2) tuples:

>>> [c.bbox for c in country_subunits_by_iso_code('TM')]
[(52.5024597512, 35.2706639674, 66.5461503437, 42.7515510117)]

>>> [c.bbox for c in country_subunits_by_iso_code('GB')]
[(-5.2623046875, 51.3904296875, -2.6623046875, 53.4192871094),
 (-5.65625, 50.0213867188, 1.74658203125, 55.8079589844),
 (-8.14482421875, 54.0512695312, -5.47041015625, 55.241796875),
 (-7.54296875, 54.689453125, -0.774267578125, 60.8318847656)]

Get a set of countries by their intersection with a point:

>>> [c.name for c in
     country_subunits_containing_point(lon=-79.888252,
                                       lat=32.819747)]
['U.S.A.']

>>> [c.name for c in
     country_subunits_containing_point(lon=5.983333,
                                       lat=50.883333)]
['Germany', 'France', 'Netherlands']
