1 Overview Both government and private agencies recognize the need for accurate and com- plete road network data. Many of these agencies regularly use this type of data to manage transportation networks, analyze traffic volume, monitor real-time traf- fic flow or plan emergency responses. Sophisticated GIS applications often span multiple jurisdictions and require numerous data types and sources. As a result, in 1999, the Canadian Council on Geomatics mandated Natural Resources Canada and the Ontario Ministry of Natural Resources to standardize Canada's road cen- terline framework. is became Natural Resources Canada's (2010) National Road Network Guide to Best Practices for Data Acquisition and the standard to which the National Road Network (NRN) adheres. At Esri Canada, we have prepared this document as a revised version of the Natural Resource's NRN document. We intend for it to be used by mapping editors and GIS technicians with a focus on representing road networks within the framework of NG9-1-1, as established by the National Emergency Number Association (NENA). In this document, we follow the data needs and standards set out by NENA and the Community Map of Canada (2019), while drawing upon NG9-1-1 readiness assess- ments from ongoing consultation with Canadian municipalities and from roads and address experts. Road network data has evolved beyond local needs; instead, this type of data must meet the needs of multi-jurisdictional agencies, and it must also conform to com- mon data standards. is need has never been more obvious than with the develop- ment of the NG9-1-1 system. NENA, with input from Canadian subcommittees, has created GIS standards for supplying road network data to NG9-1-1 data aggregators. 2 Data Standards e following standards come from the document, National Road Network Guide to Best Practices for Data Acquisition. To maintain NG9-1-1 data standards, all compulsory data quality checks and attribution are described in Appendix A of this document. Beyond NG9-1-1 standards, mapping editors should also extend these standards to the generalized needs of community road networks. For all road features, mapping editors must maintain homogeneity in their data acquisition, creation and maintenance. ey should use the following guidelines: Requirements Road networks must be represented with appropriate feature attributes.
