- Migrate the database.
$ python manage.py migrate geography
Bootstrapping your database
civic-geography can bootstrap a database of US national, state and county data for you from U.S. Census cartographic boundary files, creating simplified topojson geography. Just run it!
$ python manage.py bootstrap_geography
Use the --help flag to see additional options.
Note: In order to create simplified geography, you must have topojson installed and available via command line on your machine. You can install it via npm.
$ npm install -g topojson
Publishing geography to S3
You can publish your geometries as topojson to an S3 bucket with this command. Give it a state FIPS code to bake out the geometry for that state, or use :code:00 to bake all states.
$ python manage.py bake_geography 00
