The
images of the Pitcairn Islands were captured by DigitalGlobe’s
QuickBird satellite, which was launched in 2002 to orbit at an altitude
of 450km. QuickBird’s 60 cm resolution images allow objects on the
earth's surface including houses, road centrelines and even fence lines
to be seen.
Mounted
on the satellite are two digital cameras: one 60 cm greyscale sensor
and one 2.4m colour sensor. Together, the images obtained from these
sensors can be used to plan, monitor, analyse and support a variety of
applications, including: managing the effectiveness of irrigation in
agriculture; monitoring the impact of mining on the environment; map
creation; change detection and analysis; emergency response management
services and vegetation health determination.
One
of the advantages of DigitalGlobe satellite imagery is that large
regions can be captured anywhere on the earth’s surface, which is of
particular relevance for remote areas or developing regions with
limited resources. DigitalGlobe’s image library also houses the most
comprehensive, up-to-date images available in the world. Since 2002,
QuickBird has collected imagery covering 340,000,000 square kilometres
of land and sea, and collects approximately one million square
kilometres of imagery each week.
The
latest addition to the growing constellation of DigitalGlobe commercial
sensors is the WorldView-1 satellite. Launched in September 2007, this
satellite is capable of capturing image data at 50cm resolution – now
the highest resolution commercially available.
