- Statement
- Description of data processing : Data processing has been carried out using krieging for data derived from contours, and simpler griding and merging algorithm for high data density (soundings and source DTMs).
- Description
-
Description of processed data sources :
Several sources have used among which : the multibeam echo sounder surveys from Ifremer (Seabeam, EM12D, EM 300) in the French EEZ in waters usually deeper than 200m), DTMs at 500m of resolution produced by SHOM using soundings of its bathymetric Data Base on the French continental shelf, digitized bathymetric maps pusbished by Berthois from 1974 to 1983 gridded at 500m of resolution, the SRMT 30 arc second topographic model.
