Additional Military Layers (AML) 

 

AML is a range of digital geospatial products designed to enhance situational awareness in the marine and littoral environment. Endorsed by NATO and co-ordinated by the UKHO, AML provides a tactical advantage in military and humanitarian operations through the utilisation of geospatial intelligence.

Information superiority in the maritime environment

AML is now well established as the digital product for enhancement of situational awareness in the maritime environment.  A range of vector and gridded data sets, AML provides a unified, interoperable product supporting digital navigation, access and reach of maritime forces.

AML Sample Data

AML Sample Data (Representative Data), prepared in accordance with Edition 1 of each of the six NATO endorsed product specifications, is available in self extracting zip files for download. The Representative Data is real data, typical in size and volume to that for real-time use and will only contain features and attributes relevant to the product type and availability of the source data in the area concerned. This sample data is not updated and is not intended for operational use.

As well as S-57 Base Exchange Sets (these also include New Editions); S-57 Update Exchange Sets are provided in the same way. For details of the content and coverage for each of the Base, New Editions and Update files follow the relevant link below for AML Test Data Content and Coverage

Version 1.0 S-57 Base Exchange sets (Representative)

AML V3.0 Sample Data

AML version 3.0 AML trials data , produced by the German Bundeswehr is now available for download. This trials data comprises of:

  • Bathymetric charts (CLB) in different scale bands -derived from the sea survey data base of the German Hydrographic Office.
  • Flight Aeronautical Information (FAI) - derived from NGA AVDAFIF.
  • Military Flight Information (MFI) - derived from NGA AVDAFIF.
  • Nautical chart background data (NCD) - derived from various German ENCs.
  • Q-Route (QRT), Sediment data - derived from the German Mine Warfare data centre.
  • One SBO cell containing fictitious data.
  • One LBO cell containing fictitious data.


AML Test Data

AML Standard Test Data, prepared in accordance with Edition 1 of each of the six NATO endorsed product specifications, is available in self extracting zip files for download. The Standard data is ficticious but contains at least one example of every feature class and at least one example of every possible attribute within the data model, although not all features carry the full possible attribution.

As well as S-57 Base Exchange Sets (these also include New Editions); S-57 Update Exchange sets are provided in the same way. For details of the content and coverage for each of the Base, New Editions and Update files follow the relevant link below.

Component 1, (Physical Climatology)

Test Data for IWC Component 1

Test Data is available for IWC Component 1, Physical Climatology, compliant with Component 1 (Physical Climatology) of the IWC 2.0 specification. This data set is the latest GPPDB (Gridded Physical Properties Database) climatology containing Temperature, Salinity, Sound Speed and Density at 0.25 degree spatial resolution, 32 depths levels and monthly temporal resolution. The spatial extent of this dataset covers the NW approaches. To request further information contact aml@ukho.gov.uk

Component 2 (Marine Mammals)

Test Data for IWC Component 2

Test data for IWC Component 2, Marine Mammals, can be supplied as a single NetCDF file containing Marine Mammal Distribution data for 30 species present in the NW approaches (53-61N, 19-4W). All fields, variables and attributes defined in the IWC v2.0 specification and Annex are contained in the file although some are unpopulated.

The data has a spatial resolution of 0.5 degrees and a temporal resolution of 1 month. It has been necessary due to the design of the file to repeat the RES and Density data for each month. This does not result in repetition of data and larger file sizes but does allow for refine RES and density estimates incorporating temporal variations to be included at a later date with ease.

The delivered file is ~5.5Mb in size. This suggests that a global file containing 115 species at 0.5 deg resolution would be ~2.8Gb in size.

AML Guidance and Implementation Manual

Download the 'AML Guidance and Implementation Manual' document here

This document has been produced to assist Directorates of Equipment Capability (DECs), Integrated Project Teams (IPTs) and contractors by providing guidance to the fundamental aspects of the AML concept, associated specifications/documentation and other known issues relating to the implementation of AML products.



Production Specification

NATO-endorsed Production Specifications (as distinct from the AML Product Specifications) describes details of how the content of any given AML dataset is to be encoded. This document covers the entirety of AML and is necessary to ensure that datasets are not only conformant to the AML Product Specifications but that the data produced by a wide range of producers is consistent in support of coalition interoperability.

Portrayal Specification

A portrayal specification which provides display rules and symbols for AML vector product specifications (supporting all versions) was endorsed by the NATO GMWG and published in January 2016. 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. To obtain this specification please email aml@ukho.gov.uk.
