What it does

DataGrandLyon catalogues metropolitan, municipal and partner data on Lyon's transport, planning and environment.

The licence filter matters here. The support guide distinguishes Licence Ouverte and ODbL data from mobility datasets that require an account and compliance with local public policies. Read the licence on the selected dataset before combining it with another source.

Strengths

Documented commune and projection choices on a geographic-data example
Guidance distinguishes open-data terms from account-based mobility access

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.
