From an idea sparked by a hurricane to software protecting communities worldwide.
Tickets CAD was created in 2005 by Arnold "Arnie" Shore, a retired federal communications expert from Annapolis, Maryland. After a friend working in a Florida county emergency operations center during a hurricane had no CAD software due to budget constraints, Arnie recognized that volunteer agencies across the country faced the same problem — they needed dispatch tools but couldn't afford commercial systems.
Arnie founded the Open ISES Project (Open Information Systems for Emergency Services) on SourceForge on August 2, 2005, adapting Daniel Netz's open-source PHP-Ticket system into a full computer-aided dispatch application. He served as Lead Developer and Project Leader for 18 years, joined along the way by contributors including Robert Austin, Andy Harvey, Alan Jump, Mike Harris, and Bill Kramer.
In May 2023, Arnie handed the project to Eric Osterberg (N0NKI), who continues to maintain and modernize the system. The v4.0 NewUI — a complete rewrite with a modern interface, real-time communications, and expanded integrations — is currently in active development.
