Shipping Lanes CA 2016

Shipping zones delineate activities and regulations for marine vessel traffic. Traffic lanes define specific traffic flow, while traffic separation zones assist opposing streams of marine traffic. Precautionary areas represent areas where ships must navigate with caution, and shipping safety fairways designate where artificial structures are prohibited. Recommended routes are predetermined routes for shipping adopted for reasons of safety. Areas to be avoided are within defined limits where navigation is particularly hazardous or it is exceptionally important to avoid casualties and should be avoided by all ships or certain classes of ships. Shipping Lanes and Regulations layer was created by extracting ENC (.000) files published by NOAAs Office of Coast Survey, Marine Chart Division (NOAA OCS).
