IRIS division combined with communal boundaries OpenStreetMap

Description

**Consistency between the IRIS polygons of [2013 IRIS contours] (https://www.data.gouv.fr/en/datasets/contours-iris/) and the [limits of OpenStreetMap municipalities simplified to 5m] (https://www.data.gouv.fr/en/datasets/decoupage-administratif-communal-francais-issu-d-openstreetmap/).** ![In green the municipal boundaries OSM (added). In grey the municipal boundaries IGN (deleted). In orange, the boundaries of IRIS IGN (preserved)](https://www.data.gouv.fr/s/resources/decoupage-iris-combine-aux-limites-communales-openstreetmap/20150717-001326/Screenshot_-_17072015_-_000646.png "IRIS Contours & Communes OpenStreetMap") The infra-municipal limits of IRIS are unchanged from the IGN/INSEE source. IRIS boundaries corresponding to communal boundaries are taken from the OpenStreetMap source, and IRIS are adapted accordingly. The use of this cutting with precisely geocoded data (by number) makes it possible to keep a coherence between the municipality of implementation of the geocoded point and iris code, which does not offer the source Contours IRIS whose municipal boundaries are very simplified. The attributes of the original IRIS Contours polygons are preserved in the resulting layer, with the exception of common names, taken from the OpenStreetMap source. **Format of the proposed layer** - Delivery unit France - Lambert 93 projection system (EPSG:2154) - Format ESRI Shapefile
