The Beginning

• QuickBird launched on Oct. 18, 2001
• Placed in 98 degree inclination, polar, sun
  synchronous, low earth orbit at 450 km altitude
• Based on a new 0.5 meter US Government operating
  license received December 2000
• Satellite is in optimal health and has commenced
  imaging upon completion of a verification and
  calibration period as of 1 February 2002.

Imagery for Parcel Mapping Code Enforcement
One of the most important uses for QuickBird
imagery is for property tax revenue (parcel
mapping) and building code enforcement purposes.

QuickBird Imagery is Cost Effective

• Many municipalities update 0.25-0.5m imagery
  every 3-4 years
• Municipalities cannot afford to acquire 0.25
  imagery annually
• For many purposes, higher resolution aerial
  photography is not necessary
• Satellite imagery is a cost-effective solution
  for current land base updates in interim years
• Find the change with satellite orthoimagery on an
  annual basis, focus on the change with higher
  resolution aerial orthophotos
• Satellite imagery provides current and accurate
  data needed for planning and management decisions
• Important for an enterprise GIS to link timely
  image information with other current city-wide
  databases, especially for fast growing areas
• A whole State Coverage Approach will bring cost
  savings to every organisation involved as well as
  reducing the overall spend on imagery from
  Government each year.
• Once used additional benefits will be found for
  the imagery such as those demostrated today
