m-click.aero is a very enthusiastic supporter of activities in the field of aeronautical data quality ensurement. Earlier this year, we have launched a test version of the first public web based AIXM Validation Service avaliable as both a web application and a SWIM yellow profile compatible REST service. Now, we are glad to announce that the Premium Access to AIXM Validaton Service will be grant for free for all participants of the SWIM Master Class 2015.

In order to improve the quality of information used during the Master Class, it would be very beneficial if master class participants would test their data sets against the most extensive set of validation rules provided for AIXM 5.1. Don’t forget, the data validation ability is one of the most essential SWIM infrastructure features! Take advantages of SWIM technical infrastructure, use web based validation service for free to ensure highest possible data quality: validator@m-click.aero

AIXM WFS and WPS Services – GML Applications in Aviation

The solution stack of the m-click.aero Aviation Suite product, which has been utilised in a number of research and commercial projects is based on the deegree framework. Deegree is a GML compatible, open source geographic information system developed to persist, manage, transform and expose all kinds of geographical data. Our Aviation Suite uses unique features of the deegree framework, such as document based data repository, additionally introducting extensions for aviation data formats.

Especially for the domain of AIXM 5.1 data management and processing, we additionally implemented an extended WFS 2.0 compatible query language (WFS-TE), which supports specific temporal characteristics of AIXM 5.1 beyond those provided in the basic WFS. Doing so, m-click.aero uniquely offers the full document based aviation information processing chain without internal data transformations. The aeronautical data is stored and managed exactly the same way how it is originally encoded, as native XML documents. There is no loss of information as it would sometimes be the case, when the AIXM 5.1 documents are converted into an intermediary middleware format (such as Java objects) and than again recomposed into entity relationship form suitable for final persisting in a relational database. The overall performances and scalability is much better compared to standard relational database solutions.

For detailed information please watch the video of a presentation “AIXM WFS and WPS Services – GML Applications in Aviation” (in German) held during the FOSSGIS conference 2014 by our GIS expert Markus Schneider in Berlin. Markus gives an excellent overview of the deegree framework and the m-click.aero aviation extensions.

AIXM Validation as a Service at ATIEC 2015

The United States Federal Aviation Administration (FAA), in partnership with the European Organization for the Safety of Air Navigation (EUROCONTROL), will host the 2015 Air Transportation Information Exchange Conference (ATIEC) on August 25-27, 2015 at the National Oceanic Atmospheric Administration (NOAA) Auditorium and Science Center in Silver Spring, Maryland, USA. m-click.aero has been invited to present results of collaborative work performed together with Eurocontrol and Interactive Instruments in the OGC Testbed 11 regarding the validation of aeronautical data with focus on AIXM validation as a service.


AIXM Validator Web Interface

The presentation will demonstrate the feasibility of automated, service based validation of aeronautical information represented using AIXM. The validation is based on a set of AIXM business rules that are expressed in structured English, following a profile of the Semantics of Business Vocabulary and Business Rules (SBVR). The business rules were mostly automatically converted into a set of Schematron rules. Another component, the rule validation engine, can read these rules and use them to validate AIXM data. The functionality of the validation engine is made available using the OGC Web Processing Service (WPS) interface. It can be integrated into information workflows that require the verification/validation of data, and is therefore suited to fulfill such needs for both data providers and users.

He received his Graduate Degree in Computer Technology from the Vienna University of Technology and has been working in the field of aeronautical information systems for almost 8 years. He was collaborating on the design and development of European Aeronautical database (EAD), which has been maintaining and continuously developing on behalf of Eurocontrol. Aleks’s experience ranges from software and data engineering to ATM systems definition and implementation utilising the concept of System Wide Information Management (SWIM). In September 2011 he joined the team participating in Europe’s most ambitious research and development programme, SESAR. As contributor and task leader he was participating in sub projects regarding the system wide information management (SWIM), aeronautical services and Digital NOTAM and Digital Briefing applications. He was also participating in the ongoing work on the OGC PubSub 1.0 project and for m-click.aero in the OGC Testbed 11. Aleksandar can be contacted at aleksandar.balaban (at) m-click.aero

Together with several other organisations from both Europe and the USA  m-click.aero has been chosen to contribute in the OGC Testbed 11 Aviation Thread, which has started in February 2015 and was successfully finished in the middle of June 2015. Collaborating with partners from Luciad, Snowflake Software and Interactive Systems, we worked on tasks building upon results of previous OGC testbeds.

m-click.aero’s responsibilities were to design and implement the Digital NOTAM Validation and Enrichment Services, both crucial for digital NOTAM portrayal and data quality and the key building components of a future Digital NOTAM processing and distribution workflow. As it’s unique contribution m-click.aero has provided a concept of single consolidated AIXM data repository capable to deal with both static AIXM and digital NOTAM data and successfully implemented AIXM and Digital NOTAM schema extensions with additional bidirectional entity associations.

As part of the Validation Service task we demonstrated an implementation based on the OGC WPS 1.0 service interface, which internally evaluates original SBVR Business Rules validation assertions transformed to machine readable ISO Schematron for XSLT format. m-click.aero was participating in the visualisation of aeronautical data providing an Aviation Client with Digital NOTAM portrayal and validation capabilities. Finally, we have produced an Engineering Report dedicated to the Digital NOTAM validation and enrichment with detailed implementation description and follow-up activities.

The OGC Testbed 11 Aviation Thread was sponsored by EUROCONTROL and FAA.
