politico-civic-geography

Manage political geographic and spatial data, the POLITICO way.

Creates a complete set of political geometries as topojson for export to AWS S3 or to interact with in your database.

Read the docs.

Quickstart

1. Install the app.

$ pip install politico-civic-geography

2. Add the app to your Django project and configure settings.

INSTALLED_APPS = [
    # ...
    "rest_framework",
    "geography",
]

GEOGRAPHY_AWS_REGION = "us-east-1" # default
GEOGRAPHY_AWS_S3_UPLOAD_ROOT = "elections" # default

GEOGRAPHY_API_PAGINATION_CLASS = "geography.pagination.ResultsPagination" # default

3. 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

$ make database

2. Add a connection URL to example/.env.

DATABASE_URL="postgres://localhost:5432/geography"

3. Run migrations from the example app.

$ cd example
$ pipenv run python manage.py migrate

Developing the docs

Within a pipenv shell, navigate to the docs directory and run the docs development server.

$ make livehtml
