Hydrographic survey data
Hydrographic survey data is the most detailed depth data that the Norwegian Mapping Authority, Hydrographic Service has. This data has been collected by mapping the seabed in Norwegian coastal and sea areas.
Detailed depth data for large areas of the coast has been gathered using multibeam echo sounders. Only older surveys with less detailed resolution are available for other areas. Older data is being replaced regularly as new data is collected.
Hydrographic survey data includes several types of depth information. The main products are point data with position and depth (.xyz), in addition to log data (.all). For more recent surveys, log data containing backscatter information and water column data (.wcd) is also available.

- Purpose
-
These data are used as basis for the Norwegian Hydrographic Service's digital and analog chart products and are very detailed. Data inside the territorial limit of 12 nautical miles are subject to military restrictions. This means that data more dense than 50x50 meter between the nodes are defined as classified information in coastal areas.
