Chapter 9. Use Cases Scenarios
83 The
Space Weather component of the Public Safety Geoscience Program has a
lot of geospatial data and knowledge, and this could be included in the Arctic Spatial Data Infrastructure. Collaborators in this research also involve domestic
utilities and may provide use cases of data integration use SDI between pub- licly collected data and privately held data, depending on agreement by parties
external to the program.
9.3 Marine Use Cases
Although the primary use of hydrographic data is the safety of navigation, it can serve many other purposes when included in an SDI:
• Habitat mapping and heritage assessment • Conservation assessment and designation
• Site selection e.g. renewable energy and oil and gas extraction • Route optimisation
• Vessel location and disposal monitoring • Homeland security and defence
• Aggregates extraction • Fisheries regulation
• Coastal protection and shoreline management • Licensing and consent evaluation
• Emergency planning and management • Survey planning and execution
Any emergency scenario will likely include a marine aspect, as this article
em- phasizes. The receding ice in the Arctic has been leading to increased maritime
traffic and resource exploration in areas that are not well surveyed and remote. In addition, many areas of the Arctic can only be reached by air or water. This
increases the risk for incidents such as vessel groundings, oil spills, danger to wildlife, or even human catastrophe disease. Each of these scenarios will re-
quire marine data in order to make informed decisions.
Chapter 9. Use Cases Scenarios
84 A non-hazard scenario might address the combination of available space based
imagery and Automatic Identification System AIS messages that would allow tracking of sea ice and commercial vessels operating within the Arctic SDI area
of interest. Analysis of imagery data to track ice would allow projection of fu- ture ice movement into shipping lanes indicated by regular AIS routes. In this
use case, an agency associated with an Arctic SDI member state would request monitoring of shipping lanes in their EEZ for ice intrusion and potential in-
tersection with specified vessels through the generation of an Area of Interest AOI. To do this, the agency would request access to available government li-
censed or commercially available imagery data for a specified period. This data would be made available to the Arctic ADI either through a service interface
to an Arctic SDI provided data server. Imagery analytics would determine to number and positions of sea ice objects in the defined AOI. Subsequent imagery
collections would be processed to determine the movement, and fragmentation of ice objects, as well as the entry of new ice objects into the AOI. Projections of
travel path for ice objects may be able to be predicted. At the same time, ship track data can be requested from ExactAIS WFS services. A boundary condi-
tion for nearest approach to sea ice, or projected ice oath, could be established. Warning to specific vessels could then be generated and transmitted.
Another use of AIS data is for intrusion detection and identification into envi- ronmentally sensitive areas. An agency associated with the Arctic SDI would
request monitoring of vessel traffic intruding on an area defined as environ- mentally sensitive. The agency would define the area of interest for that region.
The Arctic SDI would request AID point reports that intersect the define area of interest. The ship identification from the AIS MMSI information and location of
the intrusion would be provided as a reporting service to the requesting agency. It would also be possible to maintain a database of all intrusions. This would
allow a generation of historic patterns of intrusion for required for action. As an extension of this use case, available commercial or government licensed satellite
imagery could be conducted to confirm the identity of the MSSI information.
