Bathymetric DEM for the coasts of New-Caledonia
The bathymetric DEM for the coasts of New-Caledonia with a resolution of 0.001° (~ 100 m) was prepared in the framework of a Shom-IRD partnership as part of the TSUCAL project. The DEM covers the basin from New Caledonia in the west to the Vanuatu archipelago in the east. The DEM is designed to be used in hydrodynamic models in order to improve the pertinence of the Waves-Submersion monitoring programme.

In addition to the Shom data, the surveys of external organisms have been exploited, the contributors of which are as follows: BBundesamt für Seeschifffahrt und Hydrographie, Etablissement portuaire de Saint-Martin, Hydrographic Service of the Royal Netherlands Navy,
Institut de Physique du Globe de Paris (FEUILLET Nathalie (2009) GWADASEIS cruise, RV Le Suroît, http://dx.doi.org/10.17600/9020020), National Centre for Environmental Information,

- 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.
