Future Considerations for NENA Working Groups

[tomneer]

Purpose This issue is a parking lot for potential issues identified by the DS-Data Template Working Group to be considered in future versions of NENA documentation.

Considerations for NENA GIS Data Model v3

• Service URN (ServiceURN) field length
  • The length of the Service URN field has been requested to be extended from 50 to 55 characters (#24) to support current Service URNs defined in RFC 5031 and NENA-STA-010.x. The DS-Data Template Working Group recommends extending the length of the Service URN field to 75 or 100 characters to future-proof the field from additional Service URNs that may be assigned.
• Elevation (Elevation) field type
  • The Elevation field uses a data type of INTEGER which limits the positional accuracy of +/- 1-meter. The DS-Data Template Working Group recommends changing the Elevation data type from INTEGER to FLOAT. NENA-STA-006.2-2022 defines the Elevation values as "N" which is a non-negative integer values, changing to FLOAT which resolves elevations that may be negative.
• StateOrEquivalentsA2 field length
  • The current length of the StateOrEquivalentA2 field is 2 characters which is sufficient for the US and Canadian values. ISO 3166-2:MX uses 3 characters. The DS-Data Template Working Group recommends extending the StateOrEquivalentA2 field from 2 to 3 characters to support Mexico.
