Statement

Description of data processing :

No tide correction have been applied to the soundings obtained from IHM.

The received information was processed with Caris HIPS and SHIPS to create the GRID. From the surveys we extracted the .xyz files to make the DTM in angular coordinates at a resolution of 1/16 arc-minute of latitude and longitude. With this GRID we calculated the depth parameters (statistics). From the DTM at a resolution of 1/16 arc-minute, we have re-processed the information again with Caris HIPS and SHIPS to obtain the DTM of ¼ arc-minute
Description

Description of processed data sources :

the data sources have been obtained from surveys property of IHM (Navy Hydrographic Institute).The measuring instruments are GPSD Seastart and Seapath-204 for positioning and MBES SIMRAD EM-120 - EM-12 & EM-1002 for echosounding.
