SWIM - Applications

▪ SWIM Global Demo 2016 – Avitech, Luciad, MCAA▪ Live recording on Youtube: https://www.youtube.com/watch?v=BhMxx-FA0as

SWIM Standardization Benefits – In Theory!

▪ Seamless integration into decision support tools▪ Simple integration using open data formats and interfaces▪ Ideally a “plug-and-play” experience


QGIS; Indra Avitech SWIM; FANS Group AMDB dataQGIS; Indra Avitech SWIM; AIXM5.1 Donlon

10

Integration with QGIS

▪ QGIS – free, open source GIS tool

▪ Plugins and built-in WFS client

▪ Visualization support for AIXM 5.1

▪ Data in AIXM 5.1format over WFS v2.0▪ Data source Mongolia & Donlon


11

QGIS Integration Challenges

▪ No integration out-of-the-box:

▪ Neither QGIS built-in WFS client, nor

▪ available plugins

▪ Different interpretation of methods▪ Limited support for AIXM geometries

▪ Not all encoding types supported

▪ ElevatedPoint, ElevatedSurface, and Patches

▪ gml:pointProperty

▪ ArcByCenterPoint

▪ Map projections (axis order, etc.)▪ Referenced features▪ No support for paging▪ Minor “tweaks” needed


12

SWIM Definition and Goals▪ Definition: SWIM consists of standards, infrastructure and governance enabling the

management of ATM related information and it is exchange between qualified

parties via interoperable services [SJU & ICAO].

▪ What do we want to achieve with SWIM?

▪Easy and cost-efficient access to quality-assured data over interoperable interfaces

▪Easy and cost-efficient: Main-stream technologies

▪Quality-assured data: Processes, coding guidelines, and data validation

▪ Interoperable interfaces: Open standards and compliance testing!

OGC Compliance▪ Standards list compliance classes => text and potentially still open for interpretation

▪ Automated test suite

▪Actual proof of compliance and proper implementation

▪A community effort

▪Successfully passed test suite, a prerequisite for compliance badge and listing

▪ OGC Implementation Database

▪https://www.opengeospatial.org/resource/products/compliant

▪ Implementing – self-certification

▪Compliant – test-suite validation, monitored compliance

▪Reference Implementation – three of the first complaint implementations

▪ A topic for the SWIM Registry?

AxL WFS Certification / Compliance ▪ WFS-T v2.0

▪ Avitech is worldwide the first company to pass all tests in the OGC CITE WFS v2.0 test suite and register as compliant product!

▪ OGC officially announced on 20.11.2014 that Avitech is an early implementer.

▪ Compliance agreement countersigned (01.12.2014)

▪ Compliance received on (March, 2015), http://avitech.aero/our-products/system-wide-information-management/

▪ The AxL WFS-T service became an OGC reference implementation and stayed such ever since!

▪ https://www.opengeospatial.org/resource/products/details/?pid=1592(valid until 12/2020)

SWIM – Challenges

▪ False expectations about SWIM by some

▪ Explaining and selling SWIM when SWIM should be invisible for the end users

▪ To “see“ SWIM you need 2 “B“ for a B2B information/data exchange

▪ SWIM interoperability regarding aeronautical data requires proper AIM

deployment and interoperable data sets!

▪ Transition to SWIM and parallel support to AFTN/AMHS

▪ SWIM recognizes many standards – additional challenges for interoperability

▪ Standards are good but compliance test are better!
