Map a property's history

How it works

1. Locate the parcel. In GénéAtlas, browse the georeferenced historical cadastre and trace your parcel straight from the old plan — or start from a number and a place name.

   Tip: if the parcel is already georeferenced, click the polygon directly to create the entity from it. If the polygon doesn't exist yet, trace it yourself — your submission goes to staff for review; once accepted, you can create the parcel entity from the approved geometry.

   
2. Create the master parcel. The stable record of the property — its identity, place and cadastre reference.

   Tip: you can also create directly from the parcel table — use + Create Parcel for a single entry, or + Bulk Create to enter several parcels from the same source at once.

   

   
3. Add its events. Each mutation — sale, succession, donation, partition — is a dated event with its own owners, surfaces and act type.

   Tip: you can also create parcel events directly from a source transcription — open the source, navigate to the Transcription tab, and link or create a parcel from the document without leaving the deed.

   

   
4. Assign roles. Record who sold, bought, inherited, leased or held it in feudal tenure.
   
5. Add the neighbours. Note the abutting parcels at each date to rebuild the local layout.
6. Cite your sources. Attach the deeds, registers and mortgage formalities (4Q) that justify every step.
   
7. Read its life back. View the parcel as a branching timeline and a genealogy of mutations.
