S-102 Datasets and dataformat
The project focused on the Norwegian coast, and several areas were selected as AOI (Areas Of Interest) for operational test purposes.
Data with the required resolution and quality are not readily available for all areas and restricted by military security classification. Data with resolution of less than 50×50 m are considered confidential by law.
In order to get high resolution data for these areas, several steps had to be taken.
- Define and specify reason and purpose for the requested data
- Analyse high resolution data availability for the AOI
- Send request Norwegian Armed Forces -FOH ( All use of bathymetric data needs to be authorised by the Norwegian Armed Forces)
- If authorised, produce the dataset for the specific AOI based on requested parameters and S-102 Standard
- Download the new dataset (only to be used for project test purposes)
To demonstrate future capabilities of S-102 data for key users , a software visualisation tool was needed. The Kongsberg Digital team has in-depth experience in building 3D visualisation tools and was tasked to develop a demonstrator.
The project used an agile approach to secure the best possible result developing the S-102 Demonstrator. With an agile development methodology stakeholders/clients/endusers (in this case the Reference group) are directly involved with the development team and the requirements and solutions evolve through the collaborative effort. During the project 5 prototypes were released.
Tests in operational environment
To see the real potential in the new data type, maritime professionals with navigational expertise were involved to test the data in operational environment and real life situations.
During the project initiation phase in 2016, we invited what we considered to be the best partners to represent the professional maritime community in Norway, and luckily they all responded and committed as Reference group partners in the project.
The objective of the operational tests was to reveal value and potential associated with the new datatype through testing of specified functionalities developed in the demonstrator, using selected S-102 data in conjunction with other data types like ENC, topography etc.
The following operational tests were conducted during this project:
- VTS operation: MS Queen Victoria leaving port in Haugesund – observed from Kvitsøy Vessel Traffic Station
- Navy navigational operation: Surface and sub-surface navigation at sea in Bergen area onboard the vessel “Kvarven”, operated by the Royal Norwegian Navy
- Piloting operation: Approach to Oslo Harbour onboard Cruice ship Queen Mary 2
- Piloting operation: Anchorage operations offshore near Kårstø gas terminal Stavanger area
- Navy warfare planning operation: Test in simulators – sub surface – warfare operations
Data volume for S-102 datasets can be one of the challenges when compared to Electronic Navigational Charts (ENC). The data quantity for high resolution datasets are substantially bigger, meaning that traditional distribution methods used for ENCs are not as compatible for transporting S102 data.
The aim of the project was to find out :
- what impact larger datasets/data volumes have related to direct distribution to end-user systems
- which methods of reducing data volume would still give end users valuable data
