Coastal topo-bathymetric DEM of Tahiti

The coastal topo-bathymetric DEM of Tahiti with a resolution of 0.0002° (~ 20 m) was produced by the Shom for Météo-France (Inter-regional Direction in French Polynesia).

This DEM covers the Tahiti lagoons down to the 100 m isobath, in order to meet the need for modeling marine submersions in French Polynesia. It complements the bathymetric DEM of Tahiti and Moorea, with a resolution of 0.001° (~ 100 m).

This product is available at different vertical references, either the lowest astronomical tide (LAT) or the mean sea level (MSL).

Description

The main production tasks of this product line are based on 4 major axes each aiming at reducing the DTM uncertainties:

1) the collection, evaluation, pre-processing, and selection of data from multiple sources whose acquisition is from different sensors and time periods;

2) homogenization of the vertical and horizontal reference of the data sets;

3) the use of interpolation algorithms adapted to the heterogeneous distribution and variable density of the data, and

4) the evaluation and qualification of the final product and the elaboration of its documentation
