TRB will conduct a webinar on Tuesday, September 18, 2018, from 1:00 PM to 2:30 PM ET that examines how to process large marine vessel automatic identification system (AIS) datasets in order to maximize their usage. AIS data has evolved from simple tasks, such as mapping port traffic patterns, to more complex tasks, such as assessing locations for offshore wind farms, estimating air quality impacts from marine vessel pollutants, and evaluating corresponding exposure and risk.

The presenters will discuss the challenges they have faced working with AIS data and share how they have addressed these issues. The presenters will explain some of the potential sources of error and how to apply techniques for data culling, gap-filling, or data replacement. This webinar will also examine the advantages of data visualization, including how it may improve screening of preliminary data, identifying gaps and outliers, improving vessel type information, and evaluating spatial and temporal trends and profiles.

This webinar was organized by the TRB Standing Committee on Marine Environment.

Some registrants will need to pay $25 to attend this webinar.  Sign into to view registration information.

Webinar Outline

  1. Introduction
  2. Sources of AIS
  3. Defining spatial and temporal AIS data requirements
  4. Preprocessing steps
  5. Data cleanup
  6. Integrating activity and vessel characteristics information
  7. Auxiliary engines and boilers
  8. Computing spatially resolved results from AIS and integrated data
  9. Overview of AIS-data costing, staffing, and timelines
  10. Question and answer session

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.

Learning Objectives

At the end of this webinar, participants will be able to:

  • List the steps that should be taken to process AIS data into a useful format
  • Identify issues with AIS data and possible approaches that help mitigate these issues
  • Describe methods to link AIS vessels to vessel characteristics
  • Apply GIS data visualization tools to identify and correct data quality concerns

Professional Development Hour Information

A certificate for 1.5 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups, only the person that registers and attends the session will receive a PDH certificate. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in March 2018. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
