datamart-geo 0.2.2

Geographical location data

This package contains geospatial data and associated facilities to resolve administrative areas.

To use the fuzzy-search capabilities (GeoData.resolve_name_fuzzy()), you will need to install datamart-geo[fuzzy].

Example usage:

>>> geo_data = datamart_geo.GeoData.download()  # Download data if needed

>>> france = geo_data.resolve_name('France')
>>> france
<datamart_geo.Area "Republic of France" (3017382) type=Type.ADMIN_0>
>>> france.latitude, france.longitude
(46.0, 2.0)
>>> france.bounds
(-61.797841, 55.854503, -21.370782, 51.087541)
>>> assert france.type == datamart_geo.Type.ADMIN_0
>>> assert france.type == datamart_geo.Type.COUNTRY

>>> cuers = geo_data.resolve_name('Cuers')
>>> cuers
<datamart_geo.Area "Cuers" (6451482) type=Type.ADMIN_4>
>>> cuers.latitude, cuers.longitude
(43.2375, 6.07083)
>>> cuers.get_parent_area()
<datamart_geo.Area "Arrondissement de Toulon" (2972326) type=Type.ADMIN_3>

>>> [
...     # Show multiple results with their parent ADMIN_1
...     (a, a.get_parent_area(datamart_geo.Type.ADMIN_1))
...     for a in geo_data.resolve_name_all('Var')
... ]
[(<datamart_geo.Area "Var" (2970749) type=Type.ADMIN_2>,
  <datamart_geo.Area "Provence-Alpes-Côte d'Azur" (2985244) type=Type.ADMIN_1>),
 (<datamart_geo.Area "Vars" (6427887) type=Type.ADMIN_4>,
  <datamart_geo.Area "Nouvelle-Aquitaine" (11071620) type=Type.ADMIN_1>),
 (<datamart_geo.Area "Vars" (6442138) type=Type.ADMIN_4>,
  <datamart_geo.Area "Bourgogne-Franche-Comté" (11071619) type=Type.ADMIN_1>)]

This package was built for Auctus, the dataset search engine from NYU, to resolve named areas during profiling.
