Quick Bird Images

 


The QuickBird satellite is the first in a constellation of spacecraft that DigitalGlobe is developing that offers highly accurate, commercial high-resolution imagery of Earth. QuickBird’s global collection of panchromatic and multispectral imagery is designed to support applications ranging from map publishing to land and asset management to insurance risk assessment.

Today, DigitalGlobe’s QuickBird spacecraft is able to offer sub-meter resolution imagery, high geolocational accuracy, and large on-board data storage.
Moreover, we are able to populate and update our digitalglobe.com archive at unprecedented speed because QuickBird’s system features allow us to efficiently collect over 75 million square kilometers of imagery data annually.
