I'm giving away my discount tickets to "Business centric Open Source conference"

I'll be speaking on the tricky subject of "How to sell Open Source Software to Government", which can equally be read as "What logic can I use to convince my boss that installing Open Source is a good idea?".
This will be just one of the Open Source for Business presentations at the OSSPAC conference here in Sydney 13 & 14 of September 2010.
As a speaker, I've also managed to score a few $100 discount passes to the conference which I don't have use for. I'd hate to see them go to waste. Please contact me if you think you can make use of the pass.

OGC Webinar describing advances in GeoSpatial Standards during OWS-7 testbed

The results of this year’s main OGC testbed for GeoSpatial Standards development will be presented during an Australian / New Zealand time-zone webinar this coming
Friday 20 August 2010 at:

2:00pm: New Zealand
12 noon: Brisbane, Sydney, Canberra, Melbourne, Hobart
12:30pm: Adelaide, Darwin
10:00 am: Perth

For information and registration, see

Australian and New Zealand has played a key role in this testbed.

  • LISAsoft, Landgate, Landcare Research and CSIRO extended a Web Processing Service client to address testbed scenarios for supporting standardised algorithm access. Video at:
  • LISAsoft and CSIRO tested and recommended improvements for AIXM, an Aeronautical profile of Geographic Markup Language (GML). Video at:
  • LISAsoft defined the schema for the upcoming standard for OWS Context, a standard for storing all layers and other information on a map in a configuration file.

OGC testbeds, pilot projects and interoperability experiments are part of OGC's Interoperability Program, a global, hands-on collaborative prototyping program designed to rapidly develop, test and deliver proven candidate specifications into OGC's Specification Program, where they are formalized for public release.

The recently concluded testbed for OGC Web Services (OWS-7) covered: interoperability architectures, enhancements to existing and candidate standards for sensors, video change detection, database synchronization, information cataloguing, web processing services, event architecture and aviation.

The OGC® is an international consortium of more than 395 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.

LISAsoft is a Systems & Software Integration company with targeted expertise in GeoSpatial Standards, Spatial Data Infrastructures and Open Source Software.

Using Web Processing Services in the OGC's testbed: OWS-7

LISAsoft, in conjunction with Landgate, Landcare Research and CSIRO, recently deployed and extended a Web Processing Service client as part of the OGC's OWS-7 standards development testbed.
A Web Processing Service (WPS) provides a standard interface for applying spatial algorithms.It is particularly useful for:
  • Reducing complexity in data processing by providing plug & play algorithms.
  • Enabling processes to be chained together.
  • Enabling processing to be deployed once then used everywhere.
  • Streamlined maintenance. Processes/models are maintained in a central place by the entities who created them.
  • Taking advantage of high-speed computational capabilities on a central server.
  • Easy and interoperable access to highly complex processes, such as climate change models.
The following 3 minute video provides a demonstration of the WPS client we developed being used with the OWS-7 scenario.

Tools for developing & validating GML Application Profiles using AIXM

LISAsoft and CSIRO recently concluded validation of an Aeronautical profile for Geographic Markup Language (GML), called AIXM (Aeronautical Information Exchange Model), as part of the OGC testbed OWS-7.
Results of the project have been summarised in a 3 minute video which covers:
  • Tools for building and refactoring the AIXM application schema.
  • Tools for building Schema and Schematron validation rules from the AIXM UML/XMI model.
  • Tools for validating Web Feature Services and GML against the Schema and Schematron rules to confirm they conform to the AIXM model.
