Abstract
- Dataset description abstract
-
Data extracted from the Estonian Maritime Administrations database. Extraction has been made using a grid for data reduction and only populated cells has 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.
- Description of data processing
-
Point resolution reduction during export.
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
- 50m
- 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 IHO-S44.
- Evaluation method description
-
No validation done
