This URISA Certified Workshop is aimed at the GIS professional who is currently supporting or may support their emergency communications division in the future. In a fully operational next generation 9-1-1 system, GIS is the core component in determining how a 9-1-1 call is routed to the correct public safety answering point (PSAP). This technology shift has profound impacts on local data maintenance workflows, local data access, and data fidelity. This workshop provides an overview of next generation 9-1-1 and the role of GIS in such a system, and the implications on local workflows. It also illustrates common pain points and sources of errors in local GIS datasets.
