There are three geofence data sources in the WLC EMSA system– SRKW Closure Zones, Speed Zones, and Parking Areas. Under each data source, there are one or more geofences added to it. The alerting criteria for all of these geofences would be on enter and exit of vessel, but more specifically, on the SRKW areas, the weekly reports need to include just the vessel information for tankers and cargos. Similarly, on the speed zones, WLC is alerted when vessels are going above 14 nautical miles per hour, but also when they enter and exit. For parking areas, all vessels when they enter and exit, the alert is sent, and the report is inclusive of all traffic in the geofences.
This project was initiated by Dr. Daniela Damian, Dr. Derek Jacoby and Bachan Ghimire as a Directed Study CSC591 at UVIC for Bachan. He has made the following recommendations to WLC and SEGAL remains hopeful on having more people involved in achieving these recommendations:
“There is always this question of whether whale-watching is ethical. And if people are to observe these mammals WLC office could keep an eye of them from maintaining data of all the whale-watching boats across the coastal areas. There are companies that privately either sell or rent these boats, which left unsupervised, can cause harm to the marine life. The solution is to create a new category in AIS feed of the vessels or tag the existing ones with a label of ‘whale-watching’ to monitor activities and potentially generate reports and alerts for them.”
“Several whales around the world get injured by either getting tangled or being hit by boats. One of the strategies to lessen the occurrence of these incidents is by alerting concerned authorities of when an anchor of a vessel breaks. A potential solution is to notify the WLC office when the status of vessel changes from “At Anchor” but anomaly is detected in the course, heading, and speed, that is, identifying indicators in AIS feed that may create flags to mark an incident.”
“Should WLC decide to store the data from AIS feed, or from the reports for data analytics purposes, it can be achieved by use of cloud platforms such as Azure. Azure has support for PostGIS and PostgreSQL (the databases of the EMSA system). Dashboards such as ArcGIS serves the purpose of retaining data from the generated reports for data analytics, which is also supported in Microsoft Azure. Looking up on ArcGIS Enterprise in the Cloud is recommended.”

- Project OverviewThe requirements based on Enhanced Maritime Situational Awareness (EMSA) system are of three primary work items. First one being creation of data sources for geofences that concerns the areas of interest of WLC office. Of the created polygons as map layers, when certain trigger criteria are met within these borders, an alert either as an email or SMS are to be sent to WLC, making it the second requirement. The third one being reporting based on the actions that happen in all the geofences. This report would be a periodic weekly report generated automatically and then sent to WLC, from which the office would be able to analyze and submit the report to Transport Canada if deemed necessary.
