GIS to the Rescue: Transforming Next Gen 911 with 3D Indoor Mapping and Federal Policy

In emergencies, every second counts. The ability to locate a caller quickly and accurately can mean the difference between life and death. The session "GIS to the Rescue: 3D, Indoor Mapping, and Federal Policy," led by Keri Brennan of Geo-Comm, Inc., explored how Geographic Information Systems (GIS) and advanced mapping technologies are revolutionizing Next Generation 911 (NG9-1-1) systems. Held in W219 as part of the School and Campus Safety track, this power session highlighted the critical role of GIS in improving situational awareness, threat detection, and emergency response.

The Evolution of 911: From 1968 to Next Gen 911

The journey of 911 began in 1968 with the first emergency call. Over the decades, the system has evolved to meet the demands of modern communication. In 2000, the National Emergency Number Association (NENA) identified the need for an IP-based system to handle the growing complexity of emergency communications. By 2007, the rise of smart devices further emphasized the need for advanced systems capable of processing detailed location data.

Today, NG9-1-1 represents the future of emergency response, integrating cutting-edge technologies like GIS, 3D mapping, and Z-axis data to provide precise location information. As Keri Brennan emphasized, "Complete address information is absolutely critical to help first responders locate you."

The Role of GIS in NG9-1-1

GIS is no longer just about maps; it is a lifesaving technology. Accurate and detailed location data is essential for first responders to navigate complex environments, especially in multi-story buildings. Traditional address information is no longer sufficient—emergency systems must now provide x, y, and z-axis data to pinpoint the exact floor, room, or unit where help is needed.

Key Legislative Drivers

Several laws and regulations are shaping the implementation of NG9-1-1 systems:

1. Alyssa’s Law: Mandates silent alarm systems in schools to discreetly alert authorities during emergencies. Currently adopted in 11 states, this law underscores the need for mapping technology to support alarm systems.
   
   
2. Kari’s Law: Ensures direct access to 911 services without requiring additional dialing (e.g., dialing "9" for an outside line). This is particularly critical for businesses, hotels, and campuses.
   
   
3. Ray Baum’s Act: Requires dispatchable location information, including the specific address, floor, and room number, to be sent when 911 is dialed. This law highlights the importance of indoor maps that provide detailed floor-level data.

Challenges and Solutions: Building Sustainable Indoor Maps

One of the biggest challenges in NG9-1-1 implementation is converting raw location data into actionable information. For example, Z-axis data, which measures height above the ellipsoid, must be translated into practical floor-level details. This requires sustainable indoor mapping systems that are continuously maintained and updated.

Prioritizing Key Locations

To make NG9-1-1 a reality, Brennan outlined a phased approach, prioritizing critical locations such as:

Schools

Hospitals

Commercial spaces

Government buildings

Event venues

Manufacturing facilities

Transportation hubs

By focusing on these high-priority areas, public safety agencies can ensure that the most vulnerable and high-traffic locations are equipped with advanced mapping capabilities.

The Need for Federal Regulation and Funding

Building and maintaining these systems requires significant investment, as well as federal regulation to ensure consistency and security. Brennan emphasized the importance of workflows to collect, maintain, and share data effectively. Public safety needs its own location data model, one that is secure, sustainable, and adaptable to evolving technologies.

The Takeaway: Faster Response Saves Lives

The session concluded with a powerful reminder: "Which floor? Can be the difference between minutes and seconds." GIS and NG9-1-1 technologies are mission-critical to saving lives. By integrating 3D indoor mapping, Z-axis data, and federal policies, the future of emergency response is brighter than ever.

As Brennan aptly put it, "Lifesaving technology is no longer just a map." It is a comprehensive system that empowers first responders with the tools they need to act quickly and effectively.

The future of public safety lies in innovation, collaboration, and the integration of advanced technologies like GIS. By addressing the challenges and building sustainable systems, we can ensure that first responders are equipped to save lives—no matter where the call comes from.
