Part 2 - ENHANCED 911 REQUIREMENTS
Section 10.6.2.13 - GEOGRAPHIC INFORMATION SYSTEMS (GIS) STANDARDS
Current through Register Vol. 35, No. 18, September 24, 2024
In order to ensure that road centerline shapefiles can be effectively used and integrated at a statewide level, standards are needed for attribute data consistency and the development of spatial data by entities creating them with geographic information systems (GIS). Pursuant to 63-9D-4 NMSA 1978,a local governing body in an enhanced 911 service area shall provide GIS addressing and digital mapping to the PSAP that provides enhanced 911 service to the local governing body, as follows:
A. The attribution data content shall be derived from standards established by the national emergency number association (NENA). The attribution data format and structure is also based on, but not identical to, NENA standards.
B. The datum for geographic data shall be North American Datum 1983 (NAD 83) and the data shall be in a New Mexico state plane or universal transverse mercator (zone 12 or 13) projection. The geographic data shall be spatially complete for each GIS entity's defined area of responsibility, but must not extend past their geographic area of responsibility. Additionally, any road feature that extends beyond one entity's geographic area of responsibility shall align with the same feature maintained by the adjacent entity.
C. Spatial accuracy of geographic features is required to be such that they are representative of the actual feature at a scale of 1:5000. All geographic features shall have clean topology and shall be able to be utilized to form a statewide road network with connectivity. All attribution and geographic data shall be kept current through regular maintenance.
D. To ensure accurate dispatch call mapping, attribute data associated with GIS data shall be synchronized with MSAG and ALI data. This attribute data includes all components of road name and address ranges. Road name designations, including spelling, directional use, suffix types and abbreviations, shall match the road name values used in the MSAG. Road ranges in the GIS shall match or be included in road ranges in the MSAG.
E. The PSAP shall update the MSAG within 10 working days to reflect changes in addressing and mapping.
