Swedish territorial waters 300 m resolution
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. Calculated average depths in node position has also been exported.

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. Calculated average depths in node position has also been exported.
- 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 that can be made available according to the national security act.
- 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 200m.
- Value
- 200 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.
- Evaluation method description
-
No validation done
