The Aerodrome Mapping Exchange Model (AMXM) is a EUROCAE WG-44 / RTCA SC-217 data exchange specification for Aerodrome Mapping Databases (AMDB).

The AMXM consists of the AMXM UML Model and a derived AMXM XML Schema. The schema is a ISO/OGC GML3.2 specification for AMDB data exchange. It enables the sharing of AMDB data in accordance with EUROCAE / RTCA requirements. In combination with OGC Web Feature Service (WFS) it may be used to build SWIM information services for AMDB data. Source data may for example be available in custom GIS format (e.g. .shp), OGC GML format (e.g. AIXM5.1) and transformed into AMXM XML Schema.(read more)

AMDBs are produced and exchanged as datasets using global standards and tools of mainstream Geographic Information System (GIS) technology.  An AMDB dataset describes the spatial layout of an aerodrome in terms of features (e.g. runways, taxiways, parking stands) with geometry described as points, lines or polygons, and with attributes (e.g.  surface type) providing further information.

AMDBs are used in a wide variety of applications. Current on-board applications are intended primarily to improve the pilot’s situational awareness for surface navigation, thereby increasing safety margins and operational efficiency. Multiple user groups benefit from using AMDBs, such as pilots, controllers, aerodrome managers, and aerodrome emergency/security personnel.
