About WorldView-3
WorldView-3 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 13 August 2014 and remains operational. It is very similar to WorldView-2 but positioned in a lower orbit.
| Orbit Altitude | 617 km |
| Orbit Type | Sun-synchronous |
| Orbit Period | 97 minutes |
| Revisit Time | 1 day at 1-metre GSD resolution 4.5 days at 20° off-nadir (0.59 m GSD) |
| Equator Crossing Time | 10:30am Descending node |
WorldView-3 Objectives
WorldView-3 was the first mission to carry a multi-payload, super-spectral, high-resolution commercial satellite sensor. WorldView-3 is capable of collecting up to 680,000 km2 per day.
WorldView-3 Instruments
WorldView-110 camera (WV110)
This instrument collects images at 0.31 metre panchromatic and 1.24 metre in the eight VNIR bands, 3.7m in the eight SWIR bands and a 30 m resolution in the CAVIS (Clouds, Aerosols, Vapours, Ice and Snow) bands.
WorldView-3 has bands for enhanced multispectral analysis (coastal blue, yellow, red edge, NIR2) designed to improve segmentation and classification of land and aquatic features.

Non-scientific measuring instruments
CAVIS (Clouds, Aerosols, Vapours, Ice, and Snow): The objective of CAVIS is to monitor the atmosphere and provide correction data to improve WorldView-3's high-resolution imagery when it images Earth objects through haze, soot, dust or other obscurants.

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.
Moreover, ESA offers to registered users access through the Online Dissemination server to the following data collection:
