Both datasets have been produced by the BSR INTERREG IIIB project BALANCE. The bathymetry map consists of three maps merged together: 1. The Swedish 500 meter grid map 2. The Swedish 50 meter grid map. 3. The Danish 1:500 000 vector map. The vector map was converted to 200m grid, and the same was done to the other two maps. Then the three maps were merged to the best possible way by trying to follow the contour lines as mush as possible. In order to be displayed in the HELCOM Map Service, the map coordinate system and projection was changed from original WGS1984_UTM34N to ETRS_1989_LAEA. For more information see BALANCE Interim Report no. 10 'Towards marine landscapes in the Baltic Sea': order to be displayed in the HELCOM Map Service, the map coordinate system and projection was changed from original WGS1984_UTM34N to ETRS_1989_LAEA. Further information is also available in the BALANCE interim report No. 10 'Towards marine landscapes in the Baltic Sea': REQUIRED: The frequency with which changes and additions are made to the data set after the initial data set is completed.
