Maritime Limits

Description

Maritime Limits is a conceptual division of the Earth's water surface areas using physiographic or geopolitical criteria. As such, it usually bounds areas of exclusive national rights over mineral and biological resources, encompassing maritime features, limits and zones.

The zones of maritime boundaries are expressed in concentric limits surrounding coastal and feature baselines.

  • Inland waters—the zone inside the baseline (0-2 nm).

  • Territorial sea—the zone extending 12 nm. from the baseline (2-12 nm)

  • Contiguous zone—the area extending 24 nm. from the baseline (12-24 nm)

  • Exclusive Economic Zone—the area extending 200 nm. from the baseline except when the space between two countries. 24-200 nm)

An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the baseline out to 200 nautical miles from its coast.

Remarks

  1. The most appropriate dataset to use for EGIS would be from WMS or WFS web services as it does not require periodic updates.

Process for EGIS integration

WMS and WFS Services:

  1. These web services can be integrated directly into EGIS.

SHP File:

  1. SHP file can be integrated directly into EGIS.

TC Smart Maps:

  1. Not all GIS applications can consume KML file directly due to its unique data structures such as networklinks, folders, models etc.

  2. Please contact Lawrence Chong, Digital Services Directorate for TC Smart Maps KML dataset and format translation.

  3. TC Smart Maps KML link: \\tc.gc.ca\tcgis\GISData\Google Mashup\Marine-NWP\MaritimeLimits\MaritimeLimits.kmz

Customization:

  1. Schema transformation: As required

  2. Denormalization: Not required

  3. Value coding: Not required

  4. Attribute renaming: As required to improve readability

  5. Attribute removal: It is highly recommended as some fields are unnecessary, this will also reduce file size and improve performance

  6. Geoenrichment: Feature symbolization by Maritime Zone is recommended to improve visualization

  7. Format translation: Not required

  8. Language translation: French version not available

  9. Update frequency: As identified
