U.S. Coast Guard DistrictsThis feature layer, utilizing data from Homeland Infrastructure Foundation-Level Data (HIFLD), provides information on the U.S. Coast Guard's (USCG) Districts. Per HIFLD, the Districts cover "all nine delineated districts contained in the Code of Federal Regulation documentation. The description of the districts is established by the Commandant under the authority delegated by CFR Title 33, Chapter 1, Part 3. This layer represents land and maritime boundaries for each representative USCG district, which includes district 1, 5, 7, 8, 9, 11, 13, 14 and 17."USCG District 5Data currency: This cached Esri service is checked monthly for updates from its federal source (USCG Districts)Data modification: NoneFor more information: U.S. Coast GuardFor feedback please contact: ArcGIScomNationalMaps@esri.comHomeland Infrastructure Foundation-Level Data (HIFLD)Per HIFLD, "The Homeland Infrastructure Foundation-Level Data (HIFLD) Subcommittee was established…to address improvements in collection, processing, sharing, and protection of homeland infrastructure geospatial information across multiple levels of government, and to develop a common foundation of homeland infrastructure data to be used for visualization and analysis on all classification domains."

This is a polygonal dataset representing the U.S. Coast Guard Captain of the Port Zones throughout the United States. This data was developed by USCG - OSC Enterprise GIS based on Title 33, Code of Federal Regulations Part 3.

This data set identifies aids to navigation, or ATONs, such as lights, signals, buoys, and day beacons, that are intended to assist a navigator to determine position or safe course, or to warn of dangers or obstructions to navigation. The U.S. Coast Guard is responsible for ensuring that this network is up to date and functioning properly so recreational and commercial boaters can safely navigate the maritime environment.Direct data download | MetadataThis item is curated by the MarineCadastre.gov team.

This map service contains US Coast Guard (USCG) navigation markers for marine navigation. The markers consist of various types of lights and signs. These are fixed permanent locations. Occasionally new ones are added and old ones are removed but this is a rare occurrence.

This dataset contains a GIS database of Aids to Navigation in the Gulf of America and coastal waters of Alabama, Florida, Louisiana, Mississippi and Texas. These data were compiled on 1999-10-21. The term "Aids to Navigation" (ATONS or AIDS) refers to a device outside of a vessel used to assist mariners in determining their position or safe course, or to warn them of obstructions. AIDS to navigation include lighthouses, lights, buoy, sound signals, landmarks, RACONs, radio beacons, LORAN, and omega. These include AIDS which are installed and maintained by the Coast Guard as well as privately installed and maintained aids (permit required). This does not include unofficial AIDS (illegal) such as stakes, PVC pipes, and such placed without permission. Each USCG District Headquarters is responsible for updating their database on an "as needed" basis. When existing AIDS are destroyed or relocated and new AIDS are installed the database is updated. Each AID is assigned an official "light listing number". The light list is a document listing the current status of ATONS and it is published and distributed on a regular basis. Interim changes to the light list are published in local Notices to Mariners which are the official means which navigators are supposed to keep their charts current. In addition, the USCG broadcasts Notices to Mariners on the marine band radio as soon as changes of the status of individual AIDS are reported. The light list number and local Notices to Mariners reports are suggested ways to keep the database current on a regular or even "real time" basis. However, annual (or more frequent) updates of the entire dataset may be obtained from each USCG District Headquarters. Geographic Information System (GIS) software is required to display the data in this NCEI accession.

These data show the locations of all extant lighthouses and lights along the coast of Massachusetts. While many of the lighthouses represented are active aids to navigation maintained by the United States Coast Guard, others are not and are maintained privately. All lighthouses are shown in their current positions and may have been moved from their original locations. More details...Feature service also available.

This feature layer provides a map layer containing Safety Zones for the United States as contained in the Code of Federal Regulation documentation. A Safety Zone is a water area, shore area, or water and shore area to which, for safety or environmental purposes, access is limited to authorized persons, vehicles, or vessels. It may be stationary and described by fixed limits or it may be described as a zone around a vessel in motion. Safety zones may be established around OCS facilities being constructed, maintained, or operated on the Outer Continental Shelf to promote the safety of life and property on the facilities, their appurtenances and attending vessels, and on the adjacent waters within the safety zones.

These GIS data show the location of all United States Coast Guard facilities within Massachusetts. These were compiled by the Massachusetts Office of Coastal Zone Management; the data are current as of August 2007.

This layer is a polygonal dataset that represents land and maritime boundaries for each representative United States Coast Guard district, which includes district 1, 5, 7, 8, 9, 11, 13, 14 and 17.

The Coast Guard Sectors are delineated in the description in the Title 33 Code of Federal Regulations (CFR) for each Sector Boundary and Area of Responsibility where latitude and longitude coordinates, as well as county/state/national boundaries are included to describe the boundaries for each zone. In addition, whenever the Area of Responsibility boundary is over water, the EEZ shapefile is referenced for those occurrences. This layer displays the Coast Guard Sector Boundaries for the following sectors: Anchorage, Boston, Buffalo, Charleston, Columbia River, Corpus Christi, Delaware Bay, Detroit, Guam, Honolulu, Houston - Galveston, Humboldt Bay, Jacksonville, Juneau, Key West, Lake Michigan, Long Island Sound, Los Angeles - Long Beach, Lower Mississippi, Maryland – NCR (National Capital Region), Miami, Mobile, New Orleans, New York, North Bend, North Carolina, Northern New England, Ohio Valley, Puget Sound, San Diego, San Francisco, San Juan, Sault Ste.

Automatic identification system (AIS) data are used to identify and track vessels for various purposes (primarily navigational safety). These data can be used to study vessel traffic, such as ship routing and speed over ground (SOG). Source data were obtained from the United States Coast Guard Navigation Center (USCG NAVCEN) for the period from June 2008 to December 2015. Derived data resulting from the processing of the source data are included here. This data set presents annual raster data (1 square kilometer grid size) off California from 2008-2015 for cumulative ship traffic density (kilometers/day) and mean SOG (knots; distance-weighted). The universe of data is limited to vessels with a length greater than or equal to 80 meters. The data are analyzed in three groups: freight vessels (container, general cargo, bulk carrier, refrigerated cargo, vehicle carrier, etc.), tanker vessels (crude oil, chemical/products, liquid petroleum gas, etc.) and all vessels (the previously noted vessels, plus passenger vessels and other vessel classes). Esri ArcGIS software (ArcGIS Desktop 10.4.1) was used to process the data. The data are contained in a file geodatabase format as raster data sets. Metadata for the overall data set are contained at the level of the file geodatabase. The data were generated and used for a research article (Moore et al. 2018): Moore, T.J., Redfern, J.V., Carver, M., Hastings, S., Adams, J.D., Silber, G.K., 2018.

This layer represents Regulated Navigational Areas as specified by the National Archives and Records Administration Code of Federal Regulations, Title 33 parts 147 and 165 pertaining to the United States Coast Guard.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The Census Bureau includes landmarks such as military installations in the MTDB for locating special features and to help enumerators during field operations. In 2012, the Census Bureau obtained the inventory and boundaries of most military installations from the U.S. Department of Defense (DOD) for Air Force, Army, Marine, and Navy installations and from the U.S. Department of Homeland Security (DHS) for Coast Guard installations. The military installation boundaries in this release represent the updates the Census Bureau made in 2012 in collaboration with DoD.

These data were originally created and assembled by the NOAA Scientific Support Coordinator for US Coast Guard District Seven in circa 1992-1993 in cooperation with local Area Committees in accordance with regulations set forth by the National Response Plan of the Oil Pollution Act of 1990. They were provided to FWC-FWRI (Florida Fish and Wildlife Conservation Commission - Fish and Wildlife Research Institute, (at that time known as the Florida Marine Research Institute) in the fall of 2003 as shapefiles (in geographic, decimal degrees, NAD 83 datum) and PDF maps for each of the US Coast Guard's Marine Safety Office Areas of Responsibility (Captain of the Port Zones for Miami (at that time consisting of both Sector Miami and Sector Key West), Tampa, Jacksonville, Savannah, Charleston, and Puerto Rico/US Virgin Islands). In the Fall & Winter of 2003, FWC-FWRI map-joined all of these shapefile data layers into a single contiguous layer, then converted the data into a Microsoft Access database for updating. In the Winter & Spring of 2003-2004 FWC-FWRI updated contact information and other attribute data to expand and improve upon the database so it could be used as a core business data layer for the Marine Resources Geographic Information System (MRGIS) library. Using various spatial coding functions, such as "assign data by location", additional attribute information has been added to the spatial database. Some examples are: The NOAA Nautical Chart the point can be found on, the USGS Quad the point can be found on, the Environmental Sensitivity Index map the point can be found on, the Latitude & Longitude in two data formats (Decimal Degrees and Degrees, Minutes, Seconds (with special characters for each unit), and others. These data were maintained as a part of the MRGIS Library and used with report generating software to update the information as needed for the creation of new printed "Oil Spill Sensitive Site" record documents for spill contingency planning and response purposes. In March of 2007, FWC-FWRI partnered with USCG Sector Mobile (part of USCG District 8) to catalog the oil spill sensitive areas within the Sector Mobile boundary, which includes the Panhandle of Florida, coastal Alabama, and coastal Mississippi. Work had previously been performed in a workshop environment to identify and catalog these areas, but NOT in a spatial manner. FWRI began this work by systematically geocoding the previously identified locations and entering the attribute information that was available into the same database structure that was in place for USCG District 7 (as mentioned above). The goal was to create a consistent dataset for the southeastern United States and Puerto Rico/US Virgin Islands. Once the basic geocoding was complete, a workshop was scheduled and key stakeholder agency representatives were invited to attend and review and augment this dataset for Sector Mobile. This workshop was at the end of March 2007 and working group members were recruited from the Area Committee and those key stakeholders recommended by the Area Committee. Through the years of 2008-2009, FWC-FWRI partnered with the US Coast Guard and Florida Department of Environmental Protection - Bureau of Emergency Response to conduct a series of workshops to review and update these detailed Geographic Response Plan (GRP) data and maps for revised Digital Area Contingency Plans. As with Sector Mobile, the GRP Revision workshop attendees were from or determined by the specific Area Committee of each Sector. Please see process steps for more information about the history of the data. The process of data entry is ongoing at FWRI as of July 2011. Data will be entered and undergo quality assurance/quality control processes before new data sheets and maps are re-produced for distribution and inclusion into Digital Area Contingency Plans and other GIS and/or map products. A versioned geodatabase has been created in SQL/SDE to track changes and manage data entry as well as digital QA/QC processes, such as consistency checks. A map service has also been created that is available to all the public and stakeholder community to view the latest version of this geodata. The map service displays data directly from the Enterprise versioned database. http://ocean.floridamarine.org/acpgrp/default.aspx These data are used in BOTH a spatial manner and in the traditional database manner. The spatial version is used to produce response maps and in a GIS (The Florida Marine Spill Analysis System and Digital Area Contingency Plans) to provide timely, accurate, and valuable information to responders and in the traditional database manner to populate reports used in producing area contingency plan maps and data sheets. Maps are produced (as PDF) with the sensitive area sites depicted on them, they are then "hyperlinked" in PDF to the data sheet that contains the attribute data for the site in a customized data report form. The report form contains information on key stakeholders for the area, wildlife resources to be protected, nearby staging areas, recommended protection strategies, the latitude/longitude of the site, and other response related information needed by first responders.
