Purchase of depth data

The Danish Hydrographic Office possesses a large number of surveys of the Danish waters. The Danish Hydrographic Office’s surveys are of varying accuracy, given that the surveys are conducted at different times and with different technology. For this reason, the purchaser cannot expect all data from the surveys to be available with high accuracy.

The Danish Hydrographic Office is also in the possession of surveys that are owned by other operators, for which reason the Danish Hydrographic Office must obtain preceding permission from these other operators before data can be transferred. Please note that the Danish Defence must give a security-clearance of all transfers of depth data before the transfer can be made. We will apply for approval on your behalf.

If you wish to purchase depth data or have inquiries regarding data quality, please contact the Danish Geodata Agency at soe_policy@gst.dk .

The data price amount in 2021-level to 443 DKK exclusive of VAT, which is charged per km2. Additionally, a charge is ascribed for the time spent in relation to the transfer. The price is adjusted according to the yearly index and based on a single-user license. Multi-user licenses entail a higher cost. The purchase of depth data is restricted to internal use in the acquiring company. By default, depth data is sold in quality assured 5m-grid if the data quality permits it.

Which depth data is available?

Through the links below, you can collect an overview of which surveys the Danish Hydrographic Office stores for Denmark and Greenland. At the present moment, a similar overview does not exist regarding surveys in the Faroese waters. The overviews consist of a collection of polygons, which portray the geographic position of surveys up to and including season 2019 for Denmark and Greenland.

You must be aware of the fact that the master polygons can be opened through GIS-software, and the fact that appurtenant nautical charts do not exist in all areas, where surveys have been conducted. Metadata is registered and placed in the data for each survey.

Please contact the Danish Hydrographic Office at soe_policy@gst.dk  if you have questions regarding data, classification of ownership as well as interests.
