Additional Military Layers (AML) is a range of digital geospatial products designed to enhance situational awareness in the marine environment.
Endorsed by NATO and coordinated by the UKHO, AML provides tactical advantage in military and humanitarian operations by using geospatial intelligence. Offering a range of vector and gridded data sets, AML provides a unified, interoperable product that supports digital navigation, access and reach of maritime forces.
A portrayal specification, providing display rules and symbols for AML vector product specifications (supporting all versions), was endorsed by the NATO GMWG and published in June 2018. This builds on the IHO S-52 Presentation Library 4.0.0 and is available as a .dai file. It is intended to be implemented in systems such as WECDIS to enhance the display and usability of AML products.

It is produced by the UK Hydrographic Office (UKHO) on behalf of NATO and replaces the AML Handbook which was last revised in January 2012. The Handbook is held, maintained, configuration controlled, published and distributed in digital format.
