Aids To Navigation (ATON) Beacons - Hawaii

공공데이터포털

Displays the location of marine beacons for the State of Hawaii as recorded on NOAA nautical charts. While buoys float at the surface of the water, beacons are fixed to the sea bottom. Both are used as aids to navigation (ATONs) to indicate traffic channels, to warn against potential dangers, or for other navigational purposes. Some include lights or radar reflectors to make them visible at night and in conditions of reduced visibility. In the IALA B maritime buoyage system (North and South America), red lateral markers have even numbers and should remain on your right when returning from sea ("red, right, returning") while green lateral markers have odd numbers and should remain on your left.

AIS Ship Traffic: Mariana and Wake: 2011-2012

공공데이터포털

Ship position data from a satellite-based Automatic Identification System (AIS) were obtained jointly by PacIOOS (J. Potemra), SOEST/ORE of the University of Hawaii (E. Roth), and the Papahanaumokuakea Marine National Monument (PNMN) (D. Graham) through a one-time purchase from ORBCOMM LLC. The purchase agreement was made in late 2012 and was for a 30-by-30 degree section of historical AIS data that included the region of the Mariana Islands. The data include AIS long and unchecked reports for a one year period: August 2011 through mid-August 2012. The raw, monthly GPS files were locally converted to NetCDF for the PacIOOS data servers. Due to vendor constraints, release of the raw data is limited.

Lighthouses - Hawaii

공공데이터포털

Locations of lighthouses and minor coastal lights for the State of Hawaii. These aids to navigation (ATONs) are used to mark dangerous coastlines, hazardous shoals and reefs, and safe entries to harbors and can assist in both marine and aerial navigation. Information regarding the lamp light (color, range, elevation, etc.) is also provided as determined from NOAA nautical charts.
