Tickets CAD is a free, Open Source web-based application targeted for use by teams or agencies who need a dispatch management and tracking system but who don't have the budget required by the commercial systems. In addition to the budget issue, teams who find the commercial products not meeting their operational needs might find a solution in Tickets CAD. GPL License.
Tickets has been actively used by volunteer and HAM-oriented teams, taking advantage of the APRS interface it includes. The mapping capability, provided by integration with the Google Maps API, provides immediate access to world-wide usage, and includes geo-location functions, some name and phone-number lookup, and, importantly, driving directions (as from response unit location to incident.)
Its basic capabilities include information capture re incidents and response units - both fixed and mobile, recording important related actions, reports of several types, intrinsic chat, and notification by email (as well as 'texting' to cellphones.)
While there exist numerous commercial CAD systems out there, to the best of our knowledge Tickets CAD is the only free, Open Source CAD application available at this writing.
