How to check a French cadastral parcel on iPhone

Boundara queries IGN’s Parcellaire Express (PCI) directly. Tap the map to retrieve one parcel at a time.

Get Boundara on the App Store

Prepare before leaving mobile coverage

Check the country coverage and retrieve the parcel while connected. Save the result and confirm it can be reopened before travelling. A blank result may mean unsupported coverage or a temporarily unavailable source; it does not prove that no parcel exists.

Record the parcel identifier, source and retrieval date alongside your field notes. Compare the map with what you observe without treating GPS or a drawn line as a surveyed boundary.

Step by step

  1. Stand on the parcel. Open the satellite or standard map and tap the point. One parcel is retrieved at a time from the official service.
  2. Compare with the ground. Check the parcel geometry against what you can see, using the satellite view as a reference.
  3. Measure in place. Read approximate area, perimeter and distances directly on the map.
  4. Save and export. Save the parcel for offline reference. Pro adds notes, labels and locally stored photos, and exports PDF, GeoJSON or KML with source attribution.

  • Source: IGN, Parcellaire Express (PCI), under Open Licence 2.0.

  • The service provides national vector parcel geometry. No ownership data is requested.
  • Saved parcels, notes and photos stay on the device.

Honest limits

Read this before relying on a result.

  • Local coverage gaps are possible depending on published data.

  • They are not surveys, certificates, titles or legally valid boundary determinations.
  • Boundara is independent and is not sponsored, certified or endorsed by any public authority.

Questions

Will I see who owns a parcel?

No. The service returns geometry and basic identifiers only.

Does this replace an official cadastral document?

No. It is an informational tool; official documents come from the competent authority.

Does it work without signal?

Saved parcels open offline. Retrieving a new parcel needs the official service.

Is the measured area legally valid?

No. It is approximate and informational.
