Ministère de L'Intérieur Election Geocode to INSEE Translation Table

This repo generates a translation table mapping the weird coding scheme used by the French Ministère de L'Intérieur to the commonly-used INSEE codes predominantly used in geographical software.

Usage:

1. Install:

   m install ft-interactive/ministere-interieur-elections-to-insee --save
   

2. Require government-to-insee.json in your code:

   ES6 modules (Dependent upon transpiler/packager being able to import JSON):

   rt * as translationTable from 'ministere-interieur-elections-to-insee';
   

   CommonJS require():

   t translationTable = require('ministere-interieur-elections-to-insee');
   

3. Check translation table for government code to get corresponding INSEE code:

   t paris_1er_Arrondissement_INSEE = translationTable['75056AR01']; // Returns '75101'
   

Building:

It's inevitable that some boundary changes will occur before the next French election. To rebuild the table, you need to do a few things:

1. Clone repo:

   t clone https://github.com/ft-interactive/ministere-interieur-elections-to-insee
   

2. Install dependencies:

   npm:

   m install
   

   Yarn:

   rn install
   

3. Download the latest versions of the commune and arrondissement shapefiles from: https://www.data.gouv.fr/en/datasets/decoupage-administratif-communal-francais-issu-d-openstreetmap/

You want the latest “Export simple” and “Arrondissements Municipaux” files.

1. Move the .shp and .dbf files from each zipfile into data/

2. Copy referencePR/listeregdptcom.xml from http://elections.interieur.gouv.fr/ into data/

3. Create the JSON sources from the data:

m run convert-communes-shp && npm run convert-arrondissements-shp && npm run create-sources

1. Generate the translation table:

m run create-table

Notes:

1. There is also a CSV version generated at code-translation-table.csv in this repo.
2. The generation process compares the name strings using Dice's coefficient and reports a warning when this is less than 0.4. Any such results are saved in data/possibly-dubious-codes.
