Bathymetric DEM for the coasts of la Réunion (Homonim project)

The bathymetric DEM for the coasts of La Réunion with a resolution of 0.001° (~ 100 m) was prepared as part of the HOMONIM project.

The DEM covers the entire Reunion island. The model ranges off-shore to a depth of 4000 m.

The DEM is designed to be used in hydrodynamic models in order to produce high-precision forecasts for coastal water levels and sea conditions and therefore improve the pertinence of the Waves-Submersion monitoring programme.

Statement

In addition to the Shom data, the surveys of external organisms have been exploited, the contributors of which are as follows: DDTM 974, DEAL de La Réunion, Grand Port Maritime de La Réunion, Ifremer (SAVOYE Bruno (2006) ERODER 1 cruise, RV Beautemps-Beaupré, http://dx.doi.org/10.17600/6090020 ), IPEV, IPGP (DEPLUS Christine (2006) FOREVER cruise, RV L'Atalante, http://dx.doi.org/10.17600/6010050 ), UBO-IUEM-LDO

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.
