[gis_info] GIS for 911: Road Centerlines and Intersections

[Eric Pimpler]

Road Centerlines are required in most GIS-based 911 dispatch platforms and
are one of the five required data layers that support the core services
provided by Next Generation 911. Wherever you are in your evolution of data
maintenance and preparation for Enhanced 911 (E911) or Next Generation 911
(NG911) systems, you will eventually need to create road intersections or
run a QA/QC check to ensure your intersection topology is appropriately
configured and validating in searches and locators. This can involve a lot
of manual inspection, but it can also be streamlined through the use
geoprocessing functions, depending on your license level.

In this article, I will summarize the topology requirements for road
centerline intersections and how these data provide search results in 911
systems. I will then outline a manual process followed by a more automated
process for creating intersections in ArcGIS Pro using your road centerline
data.
