quickbird imagery is cost effective
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
