AIXM viewer temporal model

Background

The Air Traffic Management (ATM) industry is currently evolving from a legacy point-to-point system architecture to System Wide Information Management (SWIM). The goal of SWIM is to achieve global interoperability using mainstream IT technologies. To

achieve this EUROCONTROL and the Federal Aviation Association (FAA) have defined a global data exchange standard called the Aeronautical Information eXchange Model (AIXM) [url removed, login to view] . Based on XML, AIXM encodes all elements of ATM including Aerodromes, Airspace, Services, Navaids, Procedures and

Routes in XML. Many of these elements have both geospatial and temporal elements all of which require visualization

What does the application NOW do?

This viewer is a Java application which uses Snowflake's libraries for parsing Geography Markup Language (GML) to read AIXM files and

displays the AIXM features on a 3D globe using the WorldWind digital globe supplied by NASA. [url removed, login to view] This application displays the geometry and attribute information for each AIXM feature but ignores the temporal aspects of the AIXM model.

The current

application takes in information (in this case sample data) on, for example, Chicago O'Hare airport, and gives spatial information regarding objects, such as terminals, runways, etc from the AIXM. The viewer essentially takes the properties and attributes of all objects declared in the AIXM, then

visualizes it and correlates it on NASA's WindGlobe.

What SHOULD the application do?

The application only interprets and visualizes spatial data, while the xml and gml within AIXM actually includes both spatial and temporal (anything related to time) data.

In the AIXM, this change in

the attributes or properties of an object is called a Temp Delta - it contains info on what properties or attributes of an object have been changed.

The application must be able to visualise the Temp Deltas within the AIXM onto NASA's WindGlobe. The visualisation of the temporal data must be

made in the form of a "time-slide" on the application that the user can drag forwards and backwards to see the state of an airport or airspace at any given time. There will also be considerations to visual aspects indicating changes to the AIXM data - for example showing red on airspace on

any given time the airspace is closed, or runways being marked red, or it could be a form of notification e.g. exclamation sign, which, when interacted with, shows closure or any other relevant schedules for the structure e.g. runway, terminal or airspace

Project Goal

Enhance the existing

ATM viewer application so that it can interpret existing Temp Deltas from model (given in the form of sample data), and subsequently outputs a visualized form of the data on the digital globe. By the end of the project, it must have at least ONE of the following three functionalities up and

running:

o see runways being opened and closed,

o airspaces being activated and deactivated and

o navigation aids being shut down for maintenance
