ACCESS MISSION DATA

WorldView-2 is an environment-monitoring satellite from DigitalGlobe which presents images as the human eye can perceive them, creating a more realistic 'true colour' view of the world.

About WorldView-2

WorldView-2 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 8 October 2009 and remains operational.

It is the follow-on spacecraft to WorldView-1.

Mission Parameters
Orbit Altitude 770 km
Orbit Type Sun-synchronous
Orbit Period 100 minutes
Revisit Time Up to 1.1 days
Equator Crossing Time 10:30 am descending node

WorldView-2 Objectives

The overall objective is to meet the growing commercial demand for high-resolution satellite imagery. WorldView-2 provides commercially available panchromatic imagery of 0.46 m resolution, and eight-band multispectral imagery with 1.84 m resolution - representing one of the highest available spaceborne resolutions on the market.

WorldView-110 camera (WV110)

This instrument collects images at 0.41 metre panchromatic and 1.64 metre 8-band multi-spectral data. Along with the Pan (450-800 nm) and the four typical multispectral bands (blue, green, red, NIR), WorldView-2 has four additional bands for enhanced multispectral analysis (coastal blue, yellow, red edge, NIR2) designed to improve segmentation and classification of land and aquatic features.

WV110 Parameters
Imager type Pushbroom imager (or a line scan imaging system)
Imaging mode Panchromatic (Pan) Multispectral (MS) 8 bands
(4 standard + 4 additional colors)
Spectral range 450-800 nm 400-450 nm (coastal blue)
450-510 nm (blue)
510-580 nm (green)
585-625 nm (yellow)
630-690 nm (red)
705-745 nm (red edge)
770-895 nm (NIR1)
860-1040 nm (NIR2)
Spatial resolution at nadir 0.46 m GSD (0.52 m at 20º off-nadir) 1.8 m GSD (2.4 m at 20º off-nadir)
Swath width 16.4 km (multiple adjoining paths can be imaged in a target area in a single orbit pass due to S/C agility)
