资源简介：
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
