• placetype (str) – Restrict results to a particular place type.

find(*args, **kwargs)

Find candidate slugs based on full or partial path.

Parameters:

return: geojson

search(q, limit=10, country=None, region=None, placetype=None)

Search for shapes

Parameters:

• q (str) – A query string.
• limit (int) – Max number of matches to return

}

shape(*args, **kwargs)

Get the geometry for a specific slug

Parameters:

• slug – Slug identifier.
• output (str) – Desired geometry format (GeoJSON).
• geom (str) – Desired resolution for the geometry (low, medium, high).

Returns:

GeoJSON Feature

Example::

>>> from descarteslabs.client.services import Places
>>> kansas = Places().shape('north-america_united-states_kansas')
>>> kansas['bbox']
[-102.051744, 36.993016, -94.588658, 40.003078]

>>> kansas['geometry']['type']
'Polygon'

>>> kansas['properties']
