Abstract
- Dataset description abstract
-
Data extracted from the Swedish Maritime Administrations database. Extraction has been made using a grid for data reduction only and true surveyed minimum, maximum depths within the selection grid has been exported at their original positions.
- Description of processed data sources
-
As this is an extract of the entire database it consist of various sources and ages. It is still the best available dataset for the region.
- Description of data processing
-
Point resolution reduction during export. No interpolation of data.
Quality
Accuracy / Calibration
Hor. accuracy
- Measure description
-
Varying positioning methods has been used and hence it is impossible to set one value of the accuracy. It can vary from <50cm to 50m.
- Value
- 50 m
- Evaluation method description
-
No validation done.
Vert. accuracy
- Measure description
-
Varying survey methods has been used and hence it is impossible to set one value of the accuracy. All modern surveys fulfills the demands in the Finnish/Swedish realisation of IHO-S44, named FSIS-44.
For more information regarding the underlaying data quality please visit https://geokatalog.sjofartsverket.se/MapService/mapViewer.aspx?service=DjupdatatsKvalitet Where all green areas fulfills the FSIS-44, yellow areas is surveyed after 1940 and red are older digitized data.

No validation done
