Visually very appealing, but with few areas for improvement. First thing noticeable – inability to select several dates at once or a range of dates. There is no option to select several vessel types at once. Nautical boundaries visibility is scale based, but you have to zoom really close before you can see it. This does not allow for a picture of boundaries along the entire coast. Finally, data breaks once moving too far offshore, making travel routes look interrupted.
Otherwise, this is a great start with amazing visual effects. Zoom closer and click on emerging route lines to see vessel information. Read more on ArcGIS Blog here: Introducing the U.S. Vessel Traffic application from Living Atlas (esri.com)
