The effectiveness of the NG9-1-1 system will be dependent on the GIS data it uses. What is required is a rapid update system that can consume and aggregate GIS data, built from authoritative sources which meet public safety (NENA) standards.
Together with the national Emergency Services Working Group (ESWG), Esri Canada has been engaged in developing the GIS data model and standards specification and is currently assisting organizations with their management processes with respect to civic addressing standards, data governance and NG9-1-1 strategic planning.
