  Shom bathymetric datasets

For more than 200 years, Shom has maintained a bathymetric knowledge base enriched by surveys and campaigns over time. They are composed of point clouds which have a density higher than those shown on nautical charts. Datasets are stored in the Shom Bathymetric Database (BDBS) which is a source to describe seabed reliefs. These data are useful for many applications as oceanographic modeling or seabed exploitations. The bathymetric datasets have been granted a distribution agreement. Data are not modeled. This modeling is left to the initiative of the customers. In other terms, they are point clouds data on the field, treated to the hydrographic standards in force at the time of their acquisition and validated. The product is composed of bathymetric datasets which cover the entire French Exclusive Economic Zone (EEZ) as well as international waters. The cover and its cutting are available on the Shom portals (data.shom.fr). Data positions are provided in geographic coordinates reported to the World Reference Geodetic System WGS84. They are vertically referenced to the zero of the soundings reduction which is usually associated to the hydrographic Chart Datum of the corresponding area. For depths up to 50m, the data vertical accuracy varies from 30cm to 1m and the planimetric accuracy varies from 1 to 20m. Beyond, in deep seas, the vertical accuracy is mainly of the order of 1 to 2% of the bottom depth. Sometimes, it is higher depending on the technology used.

Statement

Bathymetric datasets are an extraction of surveys belonging to the Shom public database. They go through a quality control before integration. From 1968, datasets are in compliance with the S-44 Standards of the International Hydrographic Organization which were in effect at the time of survey. In the Shom public database, dense datasets are decimated (typically 1m for shallow waters and 100m for deep waters).
