+x C82R - 1/2/2022 8:45:14 PMIt's the map I was talking about. The 1/500000 IGN ICAO Map. It is only available from IGN. The official size of the towns are nowhere else available. You can freely access to the map through https://www.geoportail.gouv.fr/.IGN is the sole ICAO maps publisher to provide the information. Without the 1/500000 IGN ICAO map you just can't make sure that you are not braking the rule when overflying a town below 5000ft AGL.
