Coastal topo-bathymetric DEM for the Boulogne-sur-Mer harbor and the surrounding area (TANDEM project)

The coastal topo- bathymetric DEM for the coasts of Boulogne-Sur-Mer with a resolution of 0.0001° (~ 10 m) was prepared as part of the TANDEM project (Programme Investissements d'Avenir, ANR-11-RSNR-00023-01).

The DEM covers the entire Boulogne-sur-Mer port, from north of Wimereux to south of the Boulogne-sur-Mer urban sprawl.

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.

Statement

In addition to the Shom data, the surveys of external organisms have been exploited, the contributors of which are as follows: IGN, Boulogne-sur-Mer Port aurthority.

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.
