This document is the NENA recommended standard for GIS data collection and GIS data maintenance. This document is meant to provide PSAP management, vendors, and other interested parties necessary guidelines for collecting and maintaining GIS data. Collection and maintenance of GIS data is most reliably accomplished by qualified, trained individuals or vendors that have received formal GIS training and instruction.
This standard also provides information on data collection to meet accuracy requirements for wireless and Voice over Internet Protocol (VoIP) 9-1-1 technologies that use x, y, z coordinates to provide location of the 9-1-1 caller.
Mapping information at a Public Safety Answering Point (PSAP)(?) is critical to provide emergency service providers location information. Inaccurate Geographical Information System (GIS) data could mean the difference between several feet or several hundred feet, impeding effective delivery of emergency response, thus impacting lives and property.
Use of this document will:
- Ensure that GIS data collected for 9-1-1 purposes meet an accuracy standard
- Provide specific 9-1-1 GIS data maintenance guidelines
