Pyris

IRIS Insee Geolocalizer

Pyris collects some data about IRIS from the French INSEE institute. It's possible from an address to find the IRIS code and some statistics data, e.g. population, employment or housing data.

IRIS are specific codes and data related to more than 50,000 districts, built by the National Institute of Statistics and Economic Studies.

REST API documentation

api

api

For instance, you can:

  • URL/iris/0104?limit=5 to the some information about a specific IRIS code
  • URL/search/q=place de la bourse Bordeaux to get the IRIS data from a specific address

Data

You have to install postgreSQL and PostGIS. For Debian:

sudo apt-get install postgresql postgis

You have to be a PostgreSQL superuser to create the postgis extension for your database. If it's not the case, you can do:

  • su
  • su - postgres
  • psql pyris -c "CREATE EXTENSION postgis;"

All usefull scripts are in the scripts-data folder. Two steps:

  • Download and some data processing for IGN and Insee data. Take a look to the Makefile in scripts-data.
  • Then load data into your database thanks to the Python script loader.py.

To summarize, in a dedicated virtualenv, do:

  1. Go to scripts-data
  2. Run make all
  3. Run python loader.py ./data

For Python dependencies which help you to process data, take a look to the scripts-data/requirements.txt file.

You also have a configuration file example at scripts-data/settings.ini.sample.

Launch the Web App

First, download the few CSS & JavaScript dependencies with a bower install (just a Bootstrap and jQuery).

Then : > gunicorn -b 127.0.0.1:5555 pyris.api.run:app or > gunicorn -b 127.0.0.1:5555 --env PYRIS_APP_SETTINGS=./appdev.yml pyris.api.run:app if you have to specify db credentials or logging Flask app configuration.
