CITRA SATELLITE QuickBird
QuickBird is a high-resolution commercial earth observation satellite, owned by DigitalGlobe and launched in 2001 as the first satellite in a constellation of three scheduled to be in orbit by 2008. The satellite collects panchromatic (black & white) imagery at 60-70 centimeter resolution and multispectral imagery at 2.4- and 2.8-meter resolutions.
QuickBird Imagery Products offer customers a variety of options for accurate and timely imagery. Digital Globe offers QuickBird Imagery Products at three processing levels :
- Basic imagery with the least amount of processing (geometrically raw), designed for customers desiring to process imagery into a useable form themselves
- Standard Imagery with radiometric and geometric correction and delivered in a map projection
- Orthorectified Imagery with radiometric, geometric and topographic correction, and delivered in a map projection
