The Aeronautical Information Exchange Model (AIXM) is an ICAO (International Civil Aviation Organization)-based XML exchange format originating from Eurocontrol that is now readable using ArcGIS, PLTS for ArcGIS--Aeronautical Solution. Currently, AIXM contains a custom model for representing geographical features. To standardize the GIS elements of AIXM and improve our ability to read AIXM using ESRI tools, we have shown how to integrate Geography Markup Language (GML) into the AIXM specification (GML is an Open Geospatial Consortium [OGC] standard that is now undergoing the ISO standards process.). The resulting "AIXM profile of GML" defines a subset of GML geometry features and GML application schema constructs. We are planning to use this new capability to serve AIXM data through Web Feature Services (WFS) producible with IMS. Incorporating GML into AIXM should reduce the costs of using AIXM by allowing adopters to benefit from existing ArcGIS GML support.
