Quickbird imagery is cost effective l.jpg
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
