Geodata data package providing GeoJSON polygons for first-order administrative subdivisions worldwide.

Data

The data comes from Natural Earth, a public domain map dataset for cartography and GIS.

Admin1 is the biggest administrative subdivision of countries. Note that it is very heterogeneous among countries: in the United States of America, admin1 represents states, whereas they don't represent inner countries in the United Kingdom. For more information, please see official documentation or https://en.wikipedia.org/wiki/Table_of_administrative_divisions_by_country.

The admin1 resource exposes the following key properties:

  • name: common name for the subdivision.
  • admin: country name.
  • iso_3166_2: ISO 3166-2 subdivision code where available.
  • adm0_a3: ISO 3166-1 alpha-3 country code.

Preparation

To run the script:

# Install libraries
pip install -r scripts/requirements.txt

# Update the data
python scripts/process.py
