Postal code geocoding and distance calculations
pgeocode is a Python library for high performance off-line querying of GPS coordinates, region name and municipality name from postal codes. Distances between postal codes as well as general distance queries are also supported. The used GeoNames database includes postal codes for 83 countries.
Currently, only queries within the same country are supported.
For additional documentation see pgeocode.readthedocs.io.
pgeocode requires Python 2.7 or 3.5+ as well as numpy and pandas packages. It can be installed with,
pip install pgeocode
Postal code queries
>>> import pgeocode >>> nomi = pgeocode.Nominatim('fr') >>> nomi.query_postal_code("75013") postal_code 75013 country code FR place_name Paris 13 state_name Île-de-France state_code 11 county_name Paris county_code 75 community_name Paris community_code 751 latitude 48.8322 longitude 2.3561 accuracy 5 >>> nomi.query_postal_code(["75013", "69006"]) postal_code place_name state_name latitude longitude 0 75013 Paris 13 Île-de-France 48.8322 2.3561 1 69006 Lyon 06 Auvergne-Rhône-Alpes 45.7679 4.8506
>>> dist = pgeocode.GeoDistance('fr') >>> dist.query_postal_code("75013", "69006") 389.156 >>> dist.query_postal_code(["75013", "75014", "75015"], ["69006", "69005", "69004"]) array([ 389.15648697, 390.12577967, 390.49857655])
The result of a geo-localistion query is a pandas.DataFrame with the following columns,
country code: iso country code, 2 characters
postal code : postal code
place name : place name (e.g. town, city etc)
state_name : 1. order subdivision (state)
state_code : 1. order subdivision (state)
county_name : 2. order subdivision (county/province)
county_code : 2. order subdivision (county/province)
community_name : 3. order subdivision (community)
community_code : 3. order subdivision (community)
latitude : estimated latitude (wgs84)
longitude : estimated longitude (wgs84)
accuracy : accuracy of lat/lng from 1=estimated to 6=centroid
Configuration and defaults
Defaults to ~/pgeocode_data, it is the directory where data is downloaded for later consumption. It can be changed using the environment variable PGEOCODE_DATA_DIR, i.e. export PGEOCODE_DATA_DIR=/tmp/pgeocode_data.
