United Kingdom Digital Marine Atlas (UKDMAP)


UKDMAP has been developed by BODC as a wide-ranging reference source for information on the coasts and seas around the UK. It contains over 1600 thematic charts which are displayed in a variety of ways including

  • contoured plots of physical, chemical and geological parameters
  • colour-coded distribution charts of sea use
  • biological and fisheries information
  • oceanographic data catalogues

As well as displaying information as geographically referenced maps, the UKDMAP software interface allows you to zoom into an area of interest and overlay charts upon one another for comparison. Many of the individual features shown on the charts can be queried for detailed information. Download the UKDMAP CDROM brochure PDF version of the UKDMAP CDROM brochure (460 KB).

Installation software update

The third edition of UKDMAP, released in July 1998, was originally distributed on CDROM for use with Windows 95/NT and has, until Windows 7, continued to operate with subsequent versions of Microsoft Windows without problem.

The installation software on the CDROM, however, will not operate with Microsoft Windows 64 bit systems. To enable the continued use of the CDROM, BODC has released updated software to allow its installation on both 32 and 64 bit Windows systems.
