Pyris

IRIS INSEE Geolocalizer

Pyris try to collect data about IRIS from the French INSEE institute. It's possible from an address to find the IRIS code and some related data.

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

Data

Setup Postgresql PoistGIS Git and Unzip

You have to install postgreSQL and PostGIS. For Debian 8:

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

sudo apt-get update

sudo apt-get install postgresql postgis git unzip

sudo service postgresql restart

Setup Pyris

git clone https://github.com/flaborde/pyris.git

cd pyris && mkdir data

cd bin

./import-data.sh  --gosu-postgres

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;"

Test the insertion with a simple:

SELECT gid,depcom,nom_com,iris,typ_iris
FROM geoiris LIMIT 10;

REST API

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
