California Highway Patrol E-911 Enterprise GIS

Client: California Highway Patrol

Challenge

The California Highway Patrol (CHP) is in the process of migrating from a legacy mainframe-based Computer Aided Dispatch (CAD) system. CHP is also the PSAP, primary call answering point, for all cellular emergency 911 calls in the state. With the statewide e911 wireless Phase II initiative (where coordinates are provided for cellular calls) nearing completion, CHP must provide mapping as a part of their legacy and new CAD system. The CHP Network Management Section, responsible for planning and implementing the CAD upgrade, decided to design and build a spatial data architecture that would support CAD and could be used by everyone at CHP.

Solution

Farallon lead a series of planning workshops with many of the primary spatial data users throughout CHP. Staff interviews included 911 call-takers and dispatchers at several of the main 911 communication centers. Based on information gathered at these interviews, Farallon identified critical GIS capabilities for supporting the way CHP uses geospatial data. The project team developed a business case for GIS that will allow the CHP to continue to effectively use its current mainframe CAD while migrating their GIS capabilities to a new enterprise system that can fully support CAD.
