Find a map after the Géoportail migration
Open Cartes.gouv.fr, recover the relevant place and layers, then check dates, scale and sharing before replacing an old Géoportail link.

The answer in 30 seconds
An old bookmark may redirect to a new interface without restoring the entire map context. Keep its original address and note the place, background, layer and zoom you needed. These details help recover a useful view if the shared link behaves differently.
The Explore maps service on Cartes.gouv.fr succeeds Géoportail. Use its help to convert an old link and then verify the place and layers actually displayed. Read each layer’s source, date and scale before measuring, citing or sharing a map.
Examples to adapt
Use the old URL and notes to reconstruct the view, then verify each layer.
Compare acquisition dates, resolution and coverage before concluding that the terrain changed.
Keep source and scale; a screenshot alone is not proof of a property boundary.
Follow the method
- 1Keep the original context
Save the Géoportail URL and accompanying notes. Distinguish place, displayed data and personal annotations; a redirect does not establish that all were preserved.
- 2Open the official explorer
Visit Cartes.gouv.fr and Explore maps. Read the viewer documentation for functions and Géoportail link conversion.
- 3Rebuild the useful view
Find the place and select the background and necessary layers. Compare them with the original purpose rather than selecting a visually similar layer without checking.
- 4Read the metadata
Record the producer, date and coverage of aerial images and thematic data. Today’s access date is not the image acquisition date.
- 5Test the new shared link
Create a share link, open it in another tab and check the result. Save a title, date and layer explanation for readers who do not know the context.
A checklist to keep
Use these checks to record your observations. They are a reading aid, not an automatic assessment.
| Check | What to examine | Action |
|---|---|---|
| Old link | URL and notes | Keep the context |
| View | Place, background, layers | Rebuild and compare |
| Data | Date, source, scale | Qualify the interpretation |
| Sharing | Tested link | Document the result |
Free, no sign-up. UTF-8 text with semicolon-separated columns.
What to check
Géoportail remains a valid name in historical references and files.
Deep zoom does not guarantee measurement precision.
Reuse conditions depend on the selected data.
Test a shared link instead of assuming it reproduces the current session.
Common questions
Should I delete old bookmarks?
Keep them until an equivalent view has been recovered and tested, then save the new link with a clear title.
Were the displayed data collected today?
Not necessarily. Interface access dates differ from image acquisition or survey dates. Read the layer metadata.
Does a visible parcel establish ownership?
No. Use appropriate legal documents and competent professionals for ownership or disputed boundaries.
