Updates: Security Theme Data

The Portal’s collection of Security maps was recently updated based on input from the Department of Defense and other federal agencies. The changes include the consolidation of maps showing military training areas into a smaller set of maps that span the full Atlantic coast and the Gulf of Mexico, the retirement of select maps, and the addition of one new map designed to aid ocean planning work.

The following data can now be accessed by clicking on the Security theme heading in Marine Planner:

  • Military Regulated Airspace: Federally authorized airpsaces with defined vertical and lateral limits that are reserved for Naval flight operations.
  • Military Use Special Airspace: Areas designated for flight operations that can require limitations be imposed on civilian and other aircraft not participating in those operations.
  • Military Surface Grid Areas: This grid-like pattern delineates a series of smaller geographic areas within the Operating Areas for administrative and ocean planning purposes.
  • Military Operating Area Boundaries: This is the bounded area in which national defense training exercises and system qualification tests are routinely conducted.

The new maps were published by the National Oceanic and Atmospheric Administration and Bureau of Ocean Energy Management on MarineCadastre.gov in partnership with the Navy.

The new layers augment an existing selection of map layers available on the Portal under the Security theme. These include the Unexploded Ordnances, Military Installation Location, and Danger Zones & Restricted Areas maps. The Portal also hosts a layer in its Renewable Energy theme called the Department of Defense Offshore Wind Mission Compatibility Assessment, which grades individual offshore wind energy lease blocks based on their compatibility with DoD operations.
