2011 West Coast Pleasure Craft and Sailing Vessel Density

Automatic Identification Systems (AIS) are a navigation safety device that transmits and monitors the location and characteristics of many vessels in U.S. and international waters in real-time. This dataset represents the density of pleasure craft and sailing vessel traffic in 2011 for the US West Coast from vessels with AIS transponders in 100 meter grid cells. The dataset is best interpreted using a high to low density scale and does not represent actual vessel counts.
