Electronic hydrographic data in chart plotters and navigation programs
Hydrographic data concerning Finnish sea areas and inland waterways displayed in chart plotters and navigation programs is, in one way or another, based on the Finnish Transport and Communication Agency Traficom’s hydrographic data.
The up-to-dateness of nautical chart data
It is up to the manufacturers to decide to what extent they will update the displayed data and follow Traficom’s schedule for official nautical chart updates. Traficom has not checked whether the data in the chart plotter systems is correct or updated. These systems do not meet the requirements of the International Maritime Organisation IMO’s performance standards for official electronic chart display and information systems (ECDIS). This is why navigation using these systems must always be based on official paper charts.
Manufacturers to whom Traficom submits digital hydrographic data
Below, there is a list of the manufacturers to whom Traficom submits digital hydrographic data. The data is delivered either as raster data or as quality-assured S-57 ENC vector data. In this context, quality-assured S-57 refers to continuously updated vector material that can be downloaded from the Traficom’s download service. The ECS systems display depth data of waterways, the depths of which have not been measured by the Traficom or its predecessors. This data is based on the Finnish Environment Institute’s depth data, and has not been produced for navigational purposes.
