Coastal topo-bathymetric DEM for the Morbihan (TANDEM project)
The coastal topo- bathymetric DEM for the coasts of Morbihan with a resolution of 0.0002° (~ 20 m) was prepared as part of the TANDEM project (Programme Investissements d'Avenir, ANR-11-RSNR-00023-01).
It covers the French administrative department of Morbihan and part of Loire-Atlantique. This DEM runs from the Gâvres peninsula in the north west to La Baule in the south east and covers the Gulf of Morbihan, the Quiberon bay and peninsula, Houat, Hoëdic and Belle-Ile islands and the Vilaine estuary.
The DEM is designed to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and English Channel, where French nuclear power plants have been installed for about 30 years.
This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.

In addition to the Shom data, the surveys of external organisms have been exploited, the contributors of which are as follows: IGN, DDE Morbihan, Institution d'Aménagement de la Vilaine, Port Atlantique-Nantes-Saint-Nazaire, Syndicat Mixte de la Ria d'Etel.
- Description
-
The main tasks involved in producing this range of solutions are based on 4 key aspects, each intended to reduce uncertainty for the DEM:
1) collecting, evaluating, pre-processing and selecting data from multiple sources after acquisition using survey systems from various eras;
2) homogenising the vertical and horizontal datums for data sets;
3) using interpolation algorithms suitable for a heterogeneous distribution and the variable density of data, and
4) evaluating and qualifying the final product and preparing documentation.
