Description
The level curves represent lines of the same altitude.
These curves are calculated every 2 metres, based on the 2012 Numerical Terrain Model (NTM).
Interpolation and smoothing do not allow an accuracy of less than 2 m in altimetry.
Altitudes are given in the "Normal Altitude" system (IGN 69).
Validity interval: from 150 to 616 m
