Wireless E-911

• Phase 0
• Locality taking the call typically on a dedicated
  seven-digit line.
• Phase I
• Call is routed through the 9-1-1 system based on
  the cell site/sector receiving the call and
  provides the cell site information and call back
  number.
• Phase II
• Same routing as Phase I, but latitude/longitude
  is provided within acceptable error rate.

26
Wireless E-911 Phase II

• Handset Based Solution - GPS
• 50 meters / 67 of the calls
• 150 meters / 95 of the calls
• Network Based Solution Triangulating
• 100 meters / 67 of the calls
• 300 meters / 95 of the calls

Wireless E-911 and VGIN

• VGIN asked to prepare a report for the 9-1-1
  Board
• VGIN analyzed wireless E-911 needs
• Sharing digital data with surrounding localities
• Must be highly accurate (cannot add to error)
• Urgently needed due to timeline and call load
• 239,000 wireless 911 calls in Fairfax, VA in FY
  2002 (53 of all 911 calls).
• 3,017,626 wireless 911 calls in Virginia in FY
  2002 (43 of all 911 calls).

35
VGIN Analysis

• Locally produced data - continue disparities
  preventing efficient sharing of data
• Commercially available data - immediately
  available and cheap but not accurate or complete
  enough
• Statewide approach - cost less than local
  approach and further all geospatial development
  within the Commonwealth (the greater good
  argument)

36
Boards Decision

• Fully fund the statewide Virginia Base Mapping
  Program (VBMP)
• Conflate/integrate existing locality centerline
  data and Virginia DOT data to the
  orthophotography
• Use census data or digitized local addressing
  data to provide addressing
• Attempt to market the digital orthophotography
  data to fund appropriate maintenance cycle
