Parcels through time
Follow a parcel across the centuries — every sale, succession and division a dated step in a branching timeline.
Land genealogy tree
Visualise the full land genealogy of a parcel — people, events and properties linked in a single connected diagram.
Online parcel creation
Trace your parcels straight onto the georeferenced historical cadastre to create them online — no GIS software required.

Owners, tenants, lords and notaries — with coats of arms, feudal titles and ties back to your family tree.
Sources & transcription
Catalogue the archives you consult, transcribe them, and back every fact with the citation that proves it.
Notaries & deeds
Keep notaries, their offices and repertories, and tie each deed to the parcels and people it names.
Feudal tenures
Document Ancien-Régime fiefs, censives, lords and dues tied to the land — what classic genealogy tools simply ignore.
Titles & mortgages
Reconstruct the mortgage registers (sous-série 4Q) — accounts, formalities and the deeds that back them.
Heraldry
Attach coats of arms and seals to families, lords or documents, with their blazon and iconographic descriptions.
Media library
Upload and organize photos and scans of your documents, stored securely with automatic thumbnails.
Statistics
Turn your data into charts and dashboards to visualize and steer your research at a glance.
Webtrees & GEDCOM
Bridge to your existing family tree — sync individuals and events via Webtrees or GEDCOM instead of duplicating your research.
What is land genealogy?
Take one concrete fact — “this plot was sold in 1850” — and give it every dimension. Land genealogy weaves four threads together:
Where — space
Locate the plot on the georeferenced historical cadastre with GénéAtlas, and trace it straight from the old plans.
When — time
Follow the parcel through its mutations — each sale, succession or division a dated step in its life.
Who — people
Put faces on the land: owners, tenants, lords and notaries, tied back to your family tree.
Proof — sources
Back every fact with the deed, register or transcription you cite — notarial acts, 4Q mortgages, feudal records.
