Navigating NENA Standards: An Overview of the GIS Standards for NG9-1-1 January 23, 2025 The transition to Next Generation 9-1-1 (NG9-1-1) is revolutionizing emergency services, and at the heart of this transformation are the National Emergency Number Association’s (NENA) standards. These standards are pivotal in ensuring that emergency response systems are efficient, accurate, reliable, and systematized. In this blog, we will delve into the significance of NENA standards and their profound impact on GIS data within NG9-1-1 environments. What Are NENA Standards? The National Emergency Number Association (NENA) plays a crucial role in shaping the future of emergency response by developing comprehensive standards and best practices that guide the implementation and operation of 9-1-1 systems. These standards encompass a wide range of critical aspects, including call routing, data management, and the integration of GIS data. By establishing a uniform framework, NENA ensures that emergency services across different regions can seamlessly communicate and collaborate, enhancing interoperability. This uniformity is vital for enabling swift and effective emergency response, ultimately saving lives and improving public safety. NENA Standards Are Essential For Several Reasons: Interoperability: By adhering to NENA standards, different emergency response systems can work together seamlessly. This interoperability is crucial for efficient and effective emergency response and to aid in the transition to NG9-1-1. Accuracy: NENA standards offer a framework to create and maintain GIS data that is complete, accurate and updated in a timely manner, which is vital for precise location validation and call routing. Consistency Across Platforms: The standards provide a framework for maintaining GIS data with high levels of data integrity and quality control, enabling consistent data across emergency response systems such as NG9-1-1 call routing, call handling equipment and Computer-Aided-Dispatch (CAD). The Role Of GIS Data In NG9-1-1: GIS data is a cornerstone of NG9-1-1 systems, playing a crucial role in enhancing the efficiency and effectiveness of emergency response. Accurate and up-to-date GIS data ensures that emergency calls are swiftly routed to the correct Public Safety Answering Point (PSAP), significantly reducing response times and improving outcomes for individuals in crisis. The seamless integration of GIS data with NG9-1-1 systems enables precise location validation and call routing, which are essential for delivering timely life-saving emergency services. This integration not only enhances the accuracy of emergency response but also ensures that resources are deployed efficiently. As we continue to advance our emergency response capabilities, the importance of robust GIS data cannot be overstated. Key NENA Standards For GIS Data i3 Architecture Standard (NENA-STA-010) – The i3 architecture standard defines the functional elements and interfaces required for NG9-1-1 systems. It includes specifications for Next Generation Core Services (NGCS) such as the Emergency Call Routing Function (ECRF) andLocation Validation Function (LVF), which rely on accurate GIS data for call routing and location validation. Civic Location Data Exchange Format (CLDXF) Standard (NENA-STA-004) – The Civic Location Data Exchange Format (CLDXF) is a standardized format for detailed location information in NGCS. It allows dynamic and precise location provisioning, driven by the Presence Information Data Format – Location Object (PIDF-LO), which encodes both civic address (e.g., 123 Main Street) and geodetic (e.g., latitude and longitude) data. CLDXF includes elements like country, state, county, municipality, neighborhood, postal code, and street information. Different profiles, such as CLDXF-US and CLDXF-CA, are tailored to the address formatting and data requirements of the United States and Canada, respectively. NENA Requirements for 3D GIS for E9-1-1 and NG9-1-1 (NENA-REQ-003) – NENA Requirements Documents help Standard Development Organizations (SDO) to identify the needs of the emergency services industry. It highlights aspects of 3D GIS for public safety systems, including:Location confidence and uncertaintyDefining “Z-Axis Capability”Methods to operationalize z-axis informationImplementing dispatchable location methodsGIS requirements for vertical structure modelingProvisioning 3D GIS information for 9-1-1 NG9-1-1 GIS Data Model Standard (NENA-STA-006) – Provides the essential schema and data requirements for GIS data used in NGCS. It includes detailed specifications for road centerlines, site/structure address points, and service boundaries. This standard provides the framework for accurate, complete and interoperable GIS data across various jurisdictions, facilitating seamless communication and collaboration in emergency response efforts. GIS Data Stewardship for NG9-1-1 Information Document (NENA-INF-028) – This document is packed with best practices for creating and maintaining top-notch GIS data. It dives into data quality measures, offers tips for coordinating with stakeholders, and provides specific recommendations for service boundary layers and civic location layers. The emphasis is on ensuring your GIS data is complete, accurate, and always up-to-date. GIS Data Transition Information Document (NENA-INF-046) – This document guides managing GIS data during the transition from legacy 9-1-1 systems to NG9-1-1. It covers synchronizing GIS data with legacy databases like the Master Street Address Guide (MSAG) and Automatic Location Identification (ALI), and explains legacy concepts to help GIS data providers support both systems. It also discusses GIS-derived MSAG considerations. Utilization of GIS Data in NGCS Information Document – This document, currently under development, will detail the use of GIS data in NGCS functional elements and provide best practices for GIS data providers. It will cover roles and responsibilities, the operation and utilization of GIS data by functional elements, and considerations for GIS data precision and tolerance. Publication is expected in 2026.
