OceanWise Marine Themes - Gridded Sea Bed DEM image

Marine Themes - Sea Bed DEM

A sea bed digital elevation model (DEM) at 1 and 6 arc seconds utilising single and multi-beam hydrographic survey data - Gridded Bathymetry.

Product Details

Created by OceanWise Ltd ​using data from the UK Hydrographic Office and other agencies. Data derived from Electronic Navigational Charts (ENCs) is used to provide additional coverage.

OceanWise Marine Themes DEM offers the following key advantages:

  • Survey data modelled to create an accurate and seamless surface of the sea bed.
  • Advanced de-confliction methodology improving continuity between surveys.
  • Height and slope attributed coastline increasing accuracy within the coastal zone.
  • Improved interpolation algorithm providing more natural shape (no flat triangles).
  • Ongoing maintenance schedule to ensure the latest survey data is incorporated.
  • Already exceptional value, DEM image files in GeoTIFF (or ECW) format provide even greater cost savings for many applications.

OceanWise Global Marine Mapping example image

Global Marine Mapping

Marine raster charts at a variety of scales, complete coverage of the world's oceans.

Product Details

UKHO charts are available for selected regions worldwide depending on international agreements. In the absence of UKHO data, other sources from the US and Russia can provide marine chart data in raster format. The US data is published by the National Geospatial Intelligence Agency between 1978-2001, and includes small scale charts of seas and regions up to very large scale charts of harbours and ports.

Please contact us if you have a requirement for overseas marine data and we can advise on availability.

BGS DigMap250 data map

BGS DiGSBS250k

A digital dataset that provides accurate mapping of the distribution of sea-bed sediment types.

Product Details

Sea-bed sediments are mapped offshore, where the most recent deposits commonly form a veneer or superficial layer of unconsolidated material on the seabed. Their distribution and composition is determined using a range of remotely sensed and physical ground truthing data. The sediment divisions on the map are primarily based on particle size analysis (PSA) of both surface sediment samples and the uppermost sediments taken from shallow cores.

Sediments are classified according to the modified Folk scale (Figure 1).The modified Folk diagram and classification used by BGS differs from that created by Folk (1954) in that the boundary between “no gravel” and “slightly gravelly” is changed from trace (0.05%) to 1% weight of particles coarser than -1Ø (2mm). The boundaries between sediment classifications or types are delineated using sample station particle size analyses and descriptions, seafloor topography derived from shallow geophysical data and, where available, multibeam bathymetry, backscatter and side scan sonar profiles.

This dataset can be used in conjunction with other BGS offshore datasets that include DiGRock250k and the DiGHardSubstrate250k datasets.
