Location Information Server (LIS) can provide location by reference or by value. If provided by value, which forms may be used?

• A. Geo only
• B. Geo or Civic
• C. Civic only
• D. Text-based coordinates

Answer: (B)

Providing location by value means sending the actual location data rather than a pointer. In a Location Information Server, the value forms you can use are geographic coordinates (Geo) or a civic address (Civic). Geo gives precise latitude/longitude (and can include altitude or accuracy), letting the PSAP place the call on a map. Civic provides a structured street address with city, state, and ZIP, which is useful for routing and verification. Text-based coordinates aren’t a standardized value form in this context and can be ambiguous to interpret, so they aren’t considered an accepted option. Therefore, the valid value forms are Geo or Civic.
