Bordeaux metropolis level curve

This dataset represents the level curves of 2001 and 2012 in the territory of the Urban Community of Bordeaux (La Cub). They are spaced 50 cm apart in elevation. It also represents the field level curves on Bordeaux Métropole resulting from the photogrammetric and lasergrammetric airborne acquisition of summer 2012. The territory of Bordeaux Métropole plus an overflow of 300 m is covered. The terrain level curves are used for the cartographic representation of the terrain. They are the result of automatic extraction, from a simplified numerical terrain model, of the lines formed by the points of the terrain located at the same altitude. The equidistance between each level curve is 50 cm.
