> The tax authorities say the software could eventually be used to find undeclared home extensions, patios or gazebos, which also play a part in property taxes.

Well, let's not be over optimistic. The PM in charge of the project on the taxe administration side is probably happy that his project is going well. However, different branches of the state are already doing that with tree line and tree coverage change for farmers subsidies. That project is not going well because of the large amount of false positives.

Trying to spot undeclared house extension will very likely follow the same path because the problem is infinitely more difficult, the data ("cadastre") is messy and Capgemini is absolutely not capable of handling that complexity by lack of skills and experience.

ok but if the tax authorities in France are anything like the tax authorities in other countries they will levy the taxes and it's up to you to prove a false positive while the fines etc. rack up.

I'm not convinced it's that difficult.

It would be pretty easy to just detect new extensions by looking at historical satellite images, and then manually check if they had approval.

Heat would also show undeclared extensions etc.
