TriTech Software Systems introduces the first in a series of “Standard Interface” Application Programming Interfaces (API) to promote industry standards for Computer-Aided Dispatch (CAD) Interoperability. The first interface guide tackles the challenges of CAD to CAD interoperability. Published after years of successful implementations, the CAD-to-CAD Interoperability Guide (CIG) is an Application Programming Interface (API) that enables multiple dispatch centers with disparate CAD systems to connect with each other and conduct seamless dispatching. Using this common protocol, agencies can manage resources across wider geographical areas by sharing units, incidents and data.
