+1, very useful site
Oui! Très cool.
Madam found Napolionic maps of our area. Thanks James will have a look there, next time it’s raining
I love géoportail. My house is on the Cassini map of my village
Geoportal also has the Plan Cadastral which is very useful when assessing potential properties.
been using it for quite while I though everyone knew about it.
Looks very interesting, James so thanks for the link, I’ve just signed up for the service.
Thanks for this!! Lovely site, yet another excuse to fritter time on line instead of daily chores.
Some years ago, I found the Napoleonic plans cadastral by going to the site of the Prefecture in Agen. I assume that all Prefectures will have access in the same way. You can look at the maps for free. There is a charge for a printed version.
You should be able to access them online via the IGN portal.
I-InfoTerre gives you the geological map of France, which I find fascinating. Under Fonds cartographiques, choose Cartes géologiques.
