Land Information Board

• The State Land Information Board was created in
  1997 by Arkansas Code 15-21-5.
• 12 members from state entities, city, county and
  local government, the private sector, and
  institutions of higher education.
• The Board supports economic development and an
  improved quality of life for Arkansas citizens by
  providing basic spatial data infrastructure,
  coordinating geographic information activities,
  and creating short- and long-term strategies that
  will result in improved decision making,
  effective asset management, and reduced costs.

What is the ACF Program?

• Scope Assemble a statewide centerline file
  better than 10 meters horizontal accuracy, with
  geocodable attributes
• Purpose Support E-911, homeland security,
  location based services, and various other state,
  federal and private activities
• Partners City, County, State, Federal, Private

21
What is the ACF Program?

• The ACF Program deals with mapping and GIS
  database standards such as map scale and column
  definitions.
• The ACF Program does not speak to addressing
  policy such as road naming conventions, signage,
  MSAG, ESN boundaries, trunking and other
  associated features of 911.

22
ACF History

• Map layer teams
• Standard published as rule and regulation
• Contact made with all counties
• Project lead hired

Problem with Typical E-911

• The traditional E-911 systems have become
  obsolete. It is estimated that 50 to 70 percent
  of emergency calls in Arkansas originate from a
  wireless/cellular device.
• Traditional E-911 systems assume the caller is
  calling from a land line and require that
  information to acquire a physical address.

45
FCC 94-102 Enhanced E-911Phase 1 Phase 2

• Phase 1 Translate the number of the wireless 911
  call and the location of the cell site receiving
  the call to the E-911 dispatcher.
• This could be used for call-back situations,
  when the cell call is dropped.
•  
• Phase 2 Provide E-911 dispatchers with the
  coordinates from which the wireless E-911 call
  was placed.
• This information can be acquired through three
  methods.

A    Cell Tower triangulation GPS
within the handset A combination of A B

Enhanced E-911Additional Information
Because the deployment of final E-911 solutions
requires the development of new technologies as
well as coordination among public safety
agencies, wireless carriers, technology vendors,
equipment manufacturers, and local exchange
carriers, the FCC established a four- year
rollout schedule of its Phase II requirements.
The rollout of Phase II began October 1, 2001
and is to be completed by December 31, 2005.

71
GPS?
72
Global Positioning SystemsHistory
Development began during Vietnam war, but was
limited to local areas. The US Department of
Defense began work on the current GPS network
in 1973 and launched the first satellite in 1978.
Civilian use was subscriber based. The full 24
satellite constellation became operational for
civilian use on April 27, 1997 .
73
Global Positioning SystemsGPS

• GPS is composed of 24 satellites circling the
  earth and a hand-held receiver that can orientate
  itself through trilateration techniques.
