happign - IGN data from R
The goal of happign is to facilitate the use of Web Services and API
from the IGN (French National Institute of Geographic and Forestry
Information). happign allow downloading of :
- Shapefile via use of WFS service and APIcarto ;
- Raster via use of WMS raster service
Context
Since January 1, 2021, the French National Institute for Geographic and Forestry Information (IGN) has opened access to their data on French topography, infrastructure, and terrain freely available. The opening of IGN data under the Etalab 2.0 open license means free access and use for all.
To facilitate accessibility, IGN has implemented a set of APIs and Web
services based on OGC standards. Despite a well supplied documentation,
the use of APIs and Web services remains complex to set up in R. The
happign package has been created to make it easier.
Rights of use for IGN data
Data from IGN geoservice website are free and available in open license according to the principle of the Etalab 2.0 license since January 1, 2021. Other data complete the IGN’s open data policy since June 1st, 2021. SCAN 25®, SCAN 100® and SCAN OACI data are free to download or stream, but any professional or individual wishing to develop a commercial paper or digital offer for the general public will have to pay a fee according to the General Conditions of Use.

Why it’s called happign ?
This project is - obviously - called happign; here’s why :
- “ign” stand for… IGN : the acronym of the institute ;
- “api” stand for… API : one of the interface used to retrieve the data;
- and the addition of an “h” and another “p” for the pun with “happy”. Besides the fact that I love this kind of humor, the simplified use of APIs is a real source of happiness, trust me.
Also, for the most attentive to details, you can see on the logo a green leaf stuck between the teeth of the charming smile. It is none other than the leaf from the IGN logo.
