Lineage
Topographic DEM - Littoral pebble spit - Baie de Somme
AREA:
The DEM concerns a portion of the littoral pebble spit of the Baie de Somme, in the sector of La Mollière (Cayeux-sur-Mer), including the upper part of the sandy intertidal zone and the active barrier spit, over 200 m in the cross-shore direction and 1200 m in the longshore direction
RESOLUTION and ACCURACY:
Resolution : 1 m
Altrimetric Accuracy : under 10 cm RMS
DATA ACQUISITION :
The DEM is derived from an airborne topographic LiDAR, Leica ALS60. Terrasolid software is used to generate a proper georeferenced point cloud using ground DEMs acquired by DGPS. The bare ground is then classified by automatic and manual extraction. The points are then averaged to create a DEM. The planimetric system used is Lambert 93 and the altimetric measurements are expressed in the IGN -69 system. For the full complex process details, see M2C laboratory.
