Image showing the BSBD  0.9.03 coverage

The previous BSBD data portal has been taken offline due to retirement of the used infrastructure on Amazon. For the time beeing replaced whith this information page. For terms and conditions see further down on this page.

This 500m bathymetric grid model is created using data from the countries around the baltic sea. Notice that this is modeled data, not actual measurements. The purpose of this database is to deliver a homogenous bathymetric model for the complete baltic sea at specfic resolutions. It is also important to notice that this data must not be used for navigation. 

To download the dataset the folowing links can be used:

BSBD 0.9.3 Bathymetry 500m grid (EPSG:3035)

Arc-Ascii Grid

32-bit GeoTIFF (app. 40MB)

BSBD 0.9.3 Density overview

Source resolution as 32-bit Geo TIFF (app. 80MB)

Source resolution as Tiff image (app. 60MB)

As a test we have published a WMTS service of a newer DTM in 250m resolution. We call this compilation BSBD 0.9.6 and it contains newer data than the previous 0.9.3 500m DTM in many areas. For the areas outside of the Kategatt area (app. Long 7E) all bathymetry used is from the GEBCO dataset. For elevations on land the NASA SRTM dataset has been used.

The BSBD 0.9.6 WMTS can be accessed using the link: for use in your own GIS, or by the use of ArcGIS-Online directly via Map viewer (test)

For download of this DTM please use the following link BSBD_0.9.6_250m
The download is a zipped file containing the DTM in 32bit Geotiff format. Geodetic reference frame is ETRS89-LAEA (EPSG:3035). The size of the download is app. 175 MB.
