Depth map special

General information

The maps on this page are built up with detailed data sets based on mapping with a multi-beam sonar. All data is taken from the Mapping Authority's open data set and is therefore free to use for both private and commercial purposes. 

For a detailed overview of coverage, you can visit dybdedata.kartverket.no .

The purpose of the maps is to show detailed depth contours in deep water. The maps will be more inaccurate near land. Some areas will be very detailed and accurate, while other areas will be less detailed and with a lesser degree of accuracy. This is because access to basic data varies from area to area.  

The maps should under no circumstances be used for navigation!

Examples from various HD depth maps.

Downloadable maps for Simrad, Lowrance and B&G

The maps are called "Crocodile <area name> HD" and are selected from the list of available maps on your chartplotter. The maps are set up with a 10-meter elevation interval throughout the depth scale, which gives a very good reproduction of structures on the seabed. The color palette that is chosen is a widely used palette for mapping the seabed and extends through the entire depth scale. It also includes a "shaded relief" map of the seabed as well as aerial photos of the land areas. Shaded relief and aerial photography are activated by turning on the "shaded relief" function on the chartplotter. There are two ways to see shaded relief. You can turn off depths and land areas in "categories" on the plotter, or you can zoom far enough out that the standard depths turn off and you see shaded relief below. The maps also contain a number of thematic data such as place names, reefs, bottom types, species observations, etc. These thematic data can also be switched off under "categories" on the plotter.

The maps have limited depth data near land.

These maps can be downloaded for a fee. The price includes any future updates of the maps, so you only pay a lump sum per. map, there will be an update to the map so you can download a new version without paying again. The links are open, so payment is based on trust.

Revenue from the sale of the maps goes to reducing costs related to software licenses, administration expenses related to the website and other expenses related to the production of the maps, including working hours. 

Mark the payment with the name of the map you are downloading .

The maps should be downloaded to PC / Mac, not mobile phone.
