The « Maritime Spatial Planning » product contains 2D areas vector objects representing the extent of the maritime spatial plan (« MSP Spatial Plan » layer) and the extent of the corresponding vocation zones (« MSP Zoning Element » layer), defined in each strategic façade document.

In early 2017, Shom established a near-bottom turbidity observation network to measure turbidity and currents near the seabed continuously, at high frequency and over a long period of time (several years). Seven mooring points with ecological and / or sedimentological interests and impacted by anthropogenic activities (except the control point in the Celtic Sea) have thus been defined. The product "Turbidity Time Series ROEC" contains turbidity level records measured in NTU by optical turbidimeters implanted at each of the 7 wetting points of the monitoring network as well as currents recordings (speed (m/s) and direction (°) measured by a single-point current meter. The data present in the product "ROEC Turbidity Time Series" corresponds to raw data from NTUS sensors (Wetlabs) and Aquadopp (Nortek) deployed on different moorings and transcoded in .CSV format. The time series are provided in their entirety and have not been post-processed. The files can therefore include certain erroneous values related to specific anomalies in the acquisition made by the sensor or intervals without data when the acquisition knows ranges of interruption.

This product includes Shom 3D digital data on tidal currents in the Channel in shapefile and geotiff formats. These digital files provide information on tidal current components (speed and direction) on an hourly basis (6 hours either side of high water for a reference port), and for two typical tidal coefficients (45 and 95). Cherbourg is taken as the reference port. Three layers are available: Surface; mid-depth; and sea-bed.

The product is a digital solution showing superficial sediments on the sea floor along coasts in mainland France.

This product includes Shom 3D digital data on tidal currents in the area "Loire" in shapefile and geotiff formats. These digital files provide information on tidal current components (speed and direction) on an hourly basis (6 hours either side of high water for a reference port), and for two typical tidal coefficients (45 and 95). Brest is taken as the reference port. Four layers are available: Surface; mid-depth; - 10 m above the sea bed and sea-bed.

The "Military practice areas" product contains vector data in the form of 2D surface objects describing the military practice areas in the France sector represented on Zonex variants of nautical charts. This is the S-57 MIPARE object class (military practice areas): maritime zone within which military, naval or air exercises can take place.

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.

This product shows the international distribution of types of tides. Four types of tides exist, and are classified based on the number and height of high and low waters each day: semi-diurnal tide: two high tides and two low tides with approximately the same height are recorded each day. Mixed tides with diurnal inequality: two high and low tides are recorded daily (just like with semi-diurnal tides), however the heights of the high and low waters vary significantly over the same day. Diurnal tides: one single high tide and one single low tide are recorded each day. Composite: tides can be diurnal or semi-diurnal or mixed.

The coastal topo-bathymetric DTM of the Arcachon basin and its surroundings at a resolution of 0.0002° (~ 20 m) was produced as part of the HOMONIM project. The DTM covers the coastline of a part of the Gironde department, from the Carcans and Hourtin ponds in the North, to the Cazaux and Sanguinet lakes in the South. It covers the entire Arcachon basin and extends offshore to about 40 m depth. The DTM is intended to be implemented in hydrodynamic models in order to produce accurate forecasts of water heights and sea states at the coast and to improve the French storm surge warning system. This product is available with the Lowest Astronomic Tide (LAT) or with the Mean Sea Level (MSL) as a vertical datum.
