Two global GIS-covers in ESRI shape format were produced: one contains polylines representing the maritime boundaries;the second holds polygons representing the EEZs. When all the boundary lines were constructed, the lines could be aggregated and an EEZ-polygon per country was derived. For the land-side border, the boundaries of the world countries were used, on the sea-side the boundaries were aggregated for each country. Separate polygons were created for islands (ex.: Azores) and dependencies (ex.: Réunion) but those polygons are linked with their corresponding sovereign nation (in the attribute table).

(Version 4.1, updated September 13, 2013) Maritime limits for the United States are measured from the U.S. baseline, recognized as the low-water line along the coast as marked on NOAA's nautical charts in accordance with the articles of the Law of the Sea. The baseline and related maritime limits are reviewed and approved by the interagency U.S. Baseline Committee. The primary purpose of this dataset is to update the official depiction of these maritime limits and boundaries on NOAA's nautical charts. The Office of Coast Survey depicts on its nautical charts the territorial sea (12 nautical miles), contiguous zone (24nm), and exclusive economic zone (200nm, plus maritime boundaries with adjacent/opposite countries). U.S. maritime limits are ambulatory and subject to revision based on accretion or erosion of the charted low water line. For more information about U.S. Maritime Limits and Boundaries and to stay up-to-date, see: http://www.nauticalcharts.noaa.gov/csdl/mbound.htm. For the full FGDC metadata record, see: http:www.ncddc.noaa.gov/approved_recs/nos_de/ocs/ocs/MB_ParentDataset.html. Coordinates for the US/Canada international boundary, on land and through the Great Lakes, are managed by the International Boundary Commission.

NOAA is responsible for depicting on its nautical charts the limits of the 12 nautical mile Territorial Sea, 24 nautical mile Contiguous Zone, and 200 nautical mile Exclusive Economic Zone (EEZ). The outer limit of each of these zones is measured from the U.S. normal baseline, which coincides with the low water line depicted on NOAA charts and includes closing lines across the entrances of legal bays and rivers, consistent with international law. The U.S. baseline and associated maritime limits are reviewed and approved through the interagency U.S. Baseline Committee, which is chaired by the U.S. Department of State. The Committee serves the function of gaining interagency consensus on the proper location of the baseline using the provisions of the 1958 Convention on the Territorial Sea and the Contiguous Zone, to ensure that the seaward extent of U.S. maritime zones do not exceed the breadth that is permitted by international law. In 2002 and in response to mounting requests for digital maritime zones, NOAA launched a project to re-evaluate the U.S. baseline in partnership with other federal agencies via the U.S. Baseline Committee. The focus of the baseline evaluation was NOAA's largest scale, most recent edition nautical charts as well as supplemental source materials for verification of certain charted features. This dataset is a result of the 2002-present initiative and reflects a multi-year iterative project whereby the baseline and associated maritime limits were re-evaluated on a state or regional basis. In addition to the U.S. maritime limits, the U.S. maritime boundaries with opposite or adjacent countries as well as the US/Canada International Boundary (on land and through the Great Lakes) are also included in this dataset.

An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a sovereign state has special rights over the exploration and use of marine resources, including energy production from water and wind. This maritime boundary is designed to be used with other marine boundaries in order to help determine areas of trade, commerce and transportation. The 200 NM zone is measured country-by-country from the baseline maritime boundary (usually, but not in all cases, the mean low-water mark used is not the same thing as the coast line). For each country, we've obtained the official list of the baseline points from the United Nations under Maritime Space.The exclusive economic zone stretches much farther into sea than the territorial waters, which end at 12 NM (22 km) from the coastal baseline (if following the rules set out in the UN Convention on the Law of the Sea). Thus, the EEZ includes the contiguous zone. States also have rights to the seabed of what is called the continental shelf up to 350 NM (648 km) from the coastal baseline, beyond the EEZ, but such areas are not part of their EEZ. The legal definition of the continental shelf does not directly correspond to the geological meaning of the term, as it also includes the continental rise and slope, and the entire seabed within the EEZ. The chart below diagrams the overlapping jurisdictions which are part of the EEZ. When the (EEZ) boundary is between countries which are separated by less than 200NM is settled by international tribunals at any arbitrary line. Many countries are still in the process of extending their EEZs beyond 200NM using criteria defined in the United Nations Convention on the Law of the Sea. Dataset Summary The data for this layer were obtained from https://www.marineregions.org/. Link to source metadata.Preferred Citation: VLIZ (2014). Maritime Boundaries Geodatabase, version 8. Available online at http://www.marineregions.org/. Consulted on 2015-03-28.These limits and boundaries were created for NOAA's internal purposes only to update the charted maritime limits and maritime boundaries on NOAA charts. These limits and boundaries do not represent the official depiction. For official depiction, please see NOAA's paper or raster nautical charts (Sourced from NOAA_Version 4.1, 9/10/2013). Also, this map service contains data from NOAA and BOEM sources and the VLIZ (2014) Maritime Boundaries Geodatabase, version 8. Available online at Marineregions.org. Consulted on 2014-12-02.What can you do with this layer?Within its EEZ, a coastal country has: (a) sovereign rights for the purpose of exploring, exploiting, conserving and managing natural resources, whether living or nonliving, of the seabed and subsoil and the superjacent waters and with regard to other activities for the economic exploitation and exploration of the zone, such as the production of energy from the water, currents and winds; (b) jurisdiction as provided for in international law with regard to the establishment and use of artificial islands, installations, and structures, marine scientific research, and the protection and preservation of the marine environment, and (c) other rights and duties provided for under international law.The features in this layer can be used for showing areas and limits of sovereignty, revenue sharing, for siting a renewable energy project, for commerce routes, and for vessel transportation tracking within ArcGIS Desktop and ArcGIS Online. An example application of the layers is listed below, from the Marine Cadastre site. If, by example, a renewable energy project is located within state waters, the rules of leasing for that particular state will apply (and therefore vary by state), and no revenues will go to the federal government.If any portion of the project location falls within the federal 8(g) zone, then 27 percent of the revenues collected by the federal government will be shared with those states whose coastlines are within 15 miles of the geographic center of the project area. If the shoreline of more than one state is within 15 miles of the geographic center of the project, all the states will share the revenue payments in proportion to the inverse distance of the nearest points of their respective coastlines to the geographic center of the project. See more on this topic at U.S.C. and C.F.R. If the location is entirely in federal waters seaward of the 8(g) zone, no collected revenues will go to the state(s).This layer is a feature service, which means it can be used for visualization and analysis throughout the ArcGIS Platform. This layer is not editable.

This is a global dataset containing maritime boundaries derived fromt the VLIZ Maritime Boundaries Geodatabase. The concept of maritime boundaries is a relative new concept. Coastal states now want to delimit an area in the ocean where they have exclusive rights over the mineral and biological resources. The basis for the calculation of maritime boundaries is the declaration of a baseline. The conditions under which a state may establish such baseline are described in the United Nations Convention on the Law of the Sea (UNCLOS). A baseline of a country can be the low water line, a straight baseline (a line that encloses bays, estuaries, inland waters,...) or a combination of the two. The zone extending 12 Nautical Miles from the baseline is the Territorial Sea and the zone extending 24 Nautical Miles is the Contiguous Zone of a country. The legal Exclusive Economic Zone is the zone extending 200 Nautical Miles from the baseline. When the space between two countries is less than 400 Nautical Miles, the boundary should be the Median Line or should be described in a multilateral treaty. Multilateral treaties and documents describing the baselines of countries can be found on the website of the United Nations (http://www.un.org/Depts/los/LEGISLATIONANDTREATIES/regionslist.htm). Those documents were a major source for the development of the database.

This edition has been superseded by the Australia's Maritime Zones Edition 4 map published in October 2013. Geocat 69822. It no longer correctly reflects Australia's maritime zones and is kept for historical record only.

This map has been derived from Geoscience Australia's Australian Maritime Boundaries (AMB) version 2.0 data which is a digital representation of Australia's territorial sea baseline and the maritime limits and boundaries as established under the Sea and Submerged Lands Act 1973.

The map describes the different maritime zones, explains how Australia defines and updates its maritime boundaries, and lists the different maritime boundary arrangements with Indonesia, Papua New Guinea, Solomon Islands, France (New Calendonia and Kerguelen) and New Zealand.

The limits of the extended continental shelf beyond the exclusive economic zone, as shown on this map, are as submitted for consideration of the United Nations Commision on the Limits of the Continental Shelf (CLCS). In accordance with Australia's request the CLCS has indicated that it will not consider the extended continental shelf appurtenant to the Australian Antarctic Territory for the time being.

This map shows the extent of Australia's maritime boundaries, stretching from Heard and McDonald Islands in the west to Norfolk Island in the east, and from the Torres Strait and Arafura Sea in the north to the Australian Antarctic Territory in the south.

This map can be purchased in either flat or folded format. Also available as GIS data or PDF.

As an island continent, Australia has sovereign rights over a vast area of ocean, along with the fishery, mineral, and petroleum resources found in that area - resources worth billions of dollars each year. The management and protection of the waters that yield these resources is, however, a complex task. Geoscience Australia has a major role in the delineation of Australia's maritime boundaries. The delineation of these boundaries has strategic, economic and environmental implications.

INSPIRE topic Maritime administrative units. These are condensed coordinates of the sea boundary maps 2920 (North Sea) and 2921 (Baltic Sea). They are coordinates condensed (interpolated) onto geodetic lines. The distance between the nodes on the geodetic connecting lines of the defined border points is less than or equal to 100 m. Germany's maritime borders were proclaimed in the European Datum 1950 (ED50) coordinate system, which is no longer common today. The basis for this determination is, in particular, the announcement of the Federal Government's proclamation on the expansion of the German territorial sea of ​​October 19, 1994 (BGBl. I p. 3428) and the Federal Republic of Germany's proclamation on the establishment of an exclusive economic zone of November 25, 1994 (BGBl. II p. 3769), which are relevant with regard to the delimitation of the German territorial sea and the German exclusive economic zone. In order to be able to use these limits better in today's GI systems and to avoid conversion errors, the BSH has derived the usage coordinates presented here in WGS 84. In this respect, they are not Germany's official maritime borders.

description: This data set contains Supplemental Official OCS Block Diagram (SOBD) images in Adobe pdf format for areas within the BOEM Gulf of Mexico Region. Each SOBD describes a single block within an Official Protraction Diagram (OPD) or Leasing Map (LM) and shows the lines (Submerged Lands Act, Limit of '8(g) Zone', maritime boundaries and/or marine sanctuaries) which occur within that block and divide it into different areas. The SOBD contains additional coordinates and area calculations for an individual block. These data are scanned images of the official paper SOBD's produced by the BOEM. Note that not all OPDs have boundaries cutting through them, so not all OPDs will have SOBDs generated for them. All current leasing activities will be done using the most current SOBDs.
