The Navigation Data Center maintains a database (Master Docks Plus) of over 40,000 port-and-waterway facilities and other navigation points of interest. The data describe the physical and inter-modal (infrastructure) characteristics of the coastal, Great Lakes, and inland ports of the United States. Data are also included for facilities in Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, and the trust territories of the Pacific. The data include, but are not limited to location (latitude/longitude, waterway, mile, and bank); operations (name, owner, operator, purpose, handling equipment, rates, and details of open-and-covered storage facilities); type and dimension of construction (length of berthing space for vessels and/or barges, depth, apron width, deck elevation, and details of rail-and-highway access); and utilities available (water, electricity, and fire protection).

The data are available in several formats.

The Complete Dock List spreadsheet contains a list of all facility types (dock, anchorage, mile point, etc) that may be reported as the origin or destination of commercial waterborne vessel moves. Attributes included in the list are the unique navigation-unit identifier, official name, facility type, latitude/longitude, United Nations Location Code, service initiation date, service termination date, port name, waterway name, and mile. Data included is for all facility types that were available for use during the previous two years.

The Port Facility spreadsheet is similar to the Complete Dock List but has an expanded list of attributes not including mile points. The additional attributes include a location description, street address, city, state, zip code, county, congressional district, owners, operators, highway-and-railway connections, commodities, type of construction, cargo-handling equipment, water depth alongside the facility, berthing space, and deck height. Data included is for all facility types (except mile points) that were available for use during the previous two years.

The Master Docks Plus Public Extract database is a Microsoft Access database that contains a complete extract of the Navigation Data Center’s dock database with all data that may be released to the public.

The Port Boundary Data identifying port boundaries are extracted from Master Dock Plus and converted into a GIS layer called Port Boundary. This GIS layer is a kmz format shape file utilizing Google Earth Pro. The port boundary is represented by the geographic location of docks and other navigation points of interest. Each facility carries essential information like Longitude, Latitude, Port ID, Mile Point, Location Code, Dock Code, Waterway, Port Facility Type and Official Dock Name. Color coded icons are used to identify the facility locations for an individual port.
