Dybdedata - dekning OGC API Features

The service provides an overview over chartered/surveyed areas of the Norwegian sea areas. Bathymetry has been collected over a long period, by various actors and with different equipment. In the attribute table of the dataset, there are details such as the year of measurement, mapping method, data owner/which actor collected the data, equipment, echo sounder type, specification, and resolution. The content of the service is based on available data from the Norwegian Mapping Authority.

This service is based on OGC API Features. OGC API is a group of new standards being developed by the Open Geospatial Consortium (OGC) to make it easier to access geographic data on the web. Not all GIS software has established support for the new standards, which may result in the functionality being somewhat slow in certain clients, such as QGIS.

Specific usage: The service can be used to get an overview of available bathymetry, for example to use in planning activities in a specific area. By using the information available in the attribute table, one can gain insights into the quality and suitability of the bathymetric data.

Newer data is considered to be of the best quality, as it has mainly been collected using multibeam echo sounders, while older data has been collected with singlebeam echo sounders or other older equipment.

The service can also be used for maps, presentations, various analyses, or as a basis for decision-making.

Statement: The service is based on the Norwegian Mapping Authority's overview of the coverage of surveyed areas. The data set is divided into polygons, where each polygon represents a survey mission and shows the extent of the surveyed area. The different surveys are identified with a unique and persistent ID, which is used as an identifier for the specific individually survey.
