IR-GIS ® Product Suite

System-engineering.jpg The IR-GIS ® Intellectual Property (for real-time processing) is available under licence or sale, contact details are included at the bottom of the main   web-page. The IP is solely owned by Ralph Holland and is unencombered and partitioned into private wikis and repositories all ready to undergo due diligence.

IR-GIS has been trade-marked by

The 2.1.X Innovative Real-time - Geographic Information System (suite) includes:

  • Overview of IR-GIS ® product
  • Technical Specifications for IR-GIS ® product
  • ir-xml real-time message formats for sensors, tracking and geodatabase storage
  • IR-GIS ® MapView 2D GIS product with real-time layers provided by ir-xml input datasources
  • IR-GIS ® MapWorld 3D GIS product with real-time layers provided by ir-xml datasources
  • IR-GIS ® HPS real-time geodatabase recording and pullback of ir-xml datasources.
  • IR-GIS ® Hps Browser - for (offline) geodatabase inspection and validation.
  • IR-GIS ® piCap - for acquisition of aircraft ADS-B position reports and amplifying data

IR-GIS ® MapView has been running since 2010 and is overlayed over the famous Open Source GIS project code which has a wide development community.


The product suite uses activemq JMS Topic and Queues for its transport and command-and-control facilities for the real-time messaging (layers).

The following utilities are used to analyse or inject messages for analysis:

  • CrossHatch - for load-testing and analysis
  • TopicToFile - for communications engineering
  • FileToTopic - for communications engineering
  • others to be documented ...


Numerous technical designs are involved in this architecture; MapView alone contains over 30,000 Java classes. Details of the design are kept in a private-wiki. All such wikis (including this one) are instances of the mediawiki - because its the best. Mediawiki has section headers, table of contents and the best things are category:Index and other categories and features, including interwiki linking (which I use between the private wikis to prevent data duplication).

capability planning

The future of the IR-GIS product has been examined with the following capability assessment which will lead to our roadmaps, which we will publish in due course:

More later.
