How to map hamlets in a rural municipality?

Updated 2 September 2026

In brief

Hamlet names a named cluster within a rural commune — often missing from generic software.
BAN provides geolocated addresses; Etalab cadastre adds parcels to situate the territory.
One map grouping addresses by hamlet helps clerk, deputy mayor, and mayor see the whole village.

In a multi-hamlet commune, the council thinks in local place names as much as street names. Mapping those groups avoids scattered spreadsheets and gives a shared base for inhabitants, parcels, and local projects.

Which data sources?

The Base Adresse Nationale lists addresses with coordinates and usually a hamlet label. Open cadastre data provides municipal parcels.

OpenStreetMap adds roads and paths. Viculus syncs these sources per commune to show addresses, hamlet outlines, and parcels on one map.

Why map hamlets?

The clerk finds an address or inhabitant by hamlet. The deputy mayor sees how the population is spread. The mayor prepares council meetings with a readable territorial view.

A sheet per hamlet (focused map, address and inhabitant lists) avoids rebuilding information by hand for every request.

Frequently asked questions

What is the difference between hamlet and lieu-dit?

In French rural administration, both often overlap: a lieu-dit names a sector of the commune, usually a hamlet or farm cluster. Viculus groups BAN addresses by lieu-dit to produce one map sheet per hamlet.

Can hamlets be mapped without heavy software?

Yes, starting from open data (BAN, cadastre) and a map-first tool. Viculus targets communes under 500 or 1,000 inhabitants: sync by INSEE code, hamlet display without complex setup.

Do addresses without a BAN hamlet label still appear?

Yes, every geolocated address is shown. Viculus also flags missing BAN hamlet labels to improve data quality — a quality dashboard is available in the app.

How are hamlet outlines drawn?

Viculus builds an envelope from hamlet addresses and nearby cadastral parcel vertices. The outline is a visual cue on the map, not an official legal boundary.

Can elected officials use the map without IT skills?

That is the goal: a full-screen map, clickable hamlets, readable sheets. No jargon, no nested menus. Secure sign-in from viculus.fr for authorised staff.
