Highlights from Living Planet Symposium

As remote sensing scientists and data-users from around the world converged at the Living Planet Symposium (LPS) in Bonn recently, a common thread was evident in many scientific sessions and meetings – the right environmental data can accelerate our understanding of the rapid changes in Earth’s system.

VHR Data Quality in the limelight

In recent years, the satellite landscape has steadily expanded with a variety of very high resolution (VHR) commercial satellites, also emerging from new space providers. A result of this growth is an increased need to address data quality assurance.

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-2 Instruments

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)
Detectors	Pan: Si CCD array (8 µm pixel size) with a row of > 35,000 detectors MS: Si CCD 4 arrays (32 µm pixel size) with a row of > 9,300 detectors
Data quantization	11 bit
Geolocation accuracy of imagery	= 3 m (using a GPS receiver, a gyroscope and a star tracker) without any GCP (Ground Control Points)
Optics	TMA telescope with an aperture diameter of 1.1 m, focal length = 13.3 m, f/12
TDI (Time Delay Integration)	6 selectable levels from 8 to 64 in Pan and MS
FOV (Field of View)	> 1.28º
Instrument size	3 m tall

DATA COLLECTIONS

These collections are available as part of the Maxar Standard Satellite Imagery products and are distributed by European Space Imaging (EUSI).

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project.

The following collections are available:
