What is AIS feed?
The Department of National Defense provides global maritime vessel data for ship tracking through the AIS (Automatic Identification System) feed.
EGIS team has been working on make the AIS feed available for the entire department through the EGIS Portal.
The team receive the URL and credentials from Alicia Hogue on July 23rd, 2019 and two different Proof-of-concepts were developed to publish data to EGIS Portal.
FME
Two separated services were created using FME desktop to publish AIS data on EGIS Dev Portal.
DND_AIS_Features_Single: This service keeps all the vessel types under the same layer allowing the user to filter and refine what is presented on the map. The service is available on the fallowing link:

DND_AIS_Features_Multi: This services generates one layer for each vessel type allowing users turn on and off the relevant data set different symbology to each vessels. The service is available on the following link:

AIS is a live feed and the data must be refreshed constantly. To do so FME provides a tool called FME Cloud that uses triggers to run the workspace base on a time schedule or when other conditions are met. As the FME Cloud was not available for tasting, a simple task schedule was set in the local machine to test the data update.
For each service, multiple and single layers, two FME workspaces were created. One workspace to fetch the data for the first time, create the layers and publish the service in the portal. The second workspace should run in a schedule, it compares the current data with the new data and updates or deletes records accordingly.
FME drawbacks and cost:
- There is no feature on FME Desktop to set hosted layer properties and symbology. A Python script can be used to set configurations when publishing the service for the first time. The updates will not change the configuration.
- There is an annual fee for Desktop license of C$3000.00 plus the FME Cloud that starts at C$0.90 per hour.

Current Services Available
Currently the AIS feed is publically available on Sandbox in the following link: https://sbxweb.tcgis.ca/portal/home/webmap/viewer.html?webmap=9b657e410e654331b0bb084ee9567b50
During the sprint 29 this service will be moved to Pilot environment where it will be shared with entire organization.
