Parent Layer: Monthly Vessel Transit Counts

Name: 2018 Monthly Tug-Tow Vessel Transit Counts

Display Field: Name

Type: Raster Catalog Layer

Geometry Type: esriGeometryPolygon

Description: This layer shows the vessel transit counts in 2018 by month for tug-tow vessels that carry Automatic Identification System (AIS) transponders. 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. The data represent vessel transit counts in 100 meter grid cells. A single transit is counted each time a vessel track passes through, starts, or stops within each grid cell.
