General Notes

• With few and justified exceptions the single location category follows the existence of a military layer in OpenStreetBrowser. Civilian locations don’t have a military layer, based on the definition.
• Airports can be defined as civilian (without military layer) or also as shared base (with military layer).
• Military training sites can be national, shared or foreign, depending from the category of other locations in this region.
• Closed base locations don’t include civilian conversion areas.

Kind of special Facilities

Command Center

A command center is normally defined with additional tags.

Use of Civilian Airport

Many military bases have not their own airfield, but use a basically civilian airport. But the difference between a civilian and military airport is not clear. Especially the airports in Afghanistan are defined as „military/civilian“ in Wikipedia.

Airplane Landings Sites and Helipads

The military defines not only Air Force bases but also all helipads as airfields.
In Visualbases all „airfields“ which can only used by helicopters are defined as helipads, different from military airplane landing sites.

Communications Station

This definition means: Radar systems and gateways as part of a global network, normally for special purpose. Mostly these installations have separate postings as special facility view and additional tags like Fac_Radar or Fac_Listening.
