What it shows

  • Cell tower and GPS coordinates triangulate concurrently with call intake
  • Deterministic rule engines classify incident priority within sub-seconds
  • Geospatial indexing matches active units by real-time distance and readiness

The takeaway

Triangulate caller position and query geospatial vehicle indexes concurrently to cut response latency.
