30-cm Color WorldView-3/4 Image of the Month – Stanley Dock Tobacco Warehouse, Liverpool, England

Every time we look at WorldView-3 and WorldView-4 (WV3/4) imagery, we are blown away. And we hope you are equally impressed with the data! In April, we were captivated by an image of the Afon Dwyryd, a river in Gwynedd, Wales. For this edition of the 30-cm Color WorldView-3/4 Image of the Month, we visit the Stanley Dock Tobacco Warehouse in Liverpool, England, considered to be the largest brick warehouse in the world.

WorldView-3 launched in late 2014 and WorldView-4 launched in late 2016; taken together they are the most advanced satellite constellation the commercial marketplace has ever had access to. Here are a few of the features that really set these satellites apart from the competition:

This month’s 30-cm WorldView-3 image features the Stanley Dock Tobacco Warehouse in Liverpool, England. It boasts a net floor area of 1.6 million square feet, making it the largest brick warehouse in the world. The 14-story building spans 36 acres and building it required 27 million bricks, 30,000 panes of glass and 8,000 tons of steel. The warehouse was a late addition to the Stanley Dock complex and was built on land reclaimed from the dock. Stanley Dock is accessible from the dock system or by barge from the Leeds and Liverpool Canal which enters under Great Howard Street bridge. With the decline of trade going through Liverpool, the warehouse was abandoned for many years and began deteriorating. Between 2015–2021, Tobacco Warehouse was redeveloped into several hundred apartments as part of a larger development of the whole Stanley Dock site. The plans involved hollowing out the center of the warehouse to create a garden-filled courtyard and the building welcomed its first residents in 2021. This 30-cm WorldView-4 image of the Stanley Dock Tobacco Warehouse was captured on Oct. 17, 2014 – so right before the redevelopment on the property commenced. The image has been processed by Apollo Mapping for improved perspective, clarity and colors. (Satellite Imagery © 2024 Maxar Technologies)
  • Improved Resolution
    • Higher resolution means you can see more detail in WV3/4 imagery.
    • Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m SWIR (WV3 only) and 30-m CAVIS (WV3 only) bands.
    • At 20 degrees off-nadir, the resolution is 34-cm panchromatic, 1.38-m visible and near infrared and 4.1-m shortwave infrared.
  • Additional Spectral Bands
    • If spectral analysis is part of your project, then no other satellite can match WV3 with its: 8 bands of visible and near-infrared data; and 8 shortwave infrared bands which are crucial for geological studies.
  • Better Positional Accuracy
    • With accuracies of 3.5-m CE90% or better (without ground control even!), WV3/4 has no rivals for its enhanced positional accuracy.
  • Daily Revisits
    • At 40 degrees latitude, WV3 is able to image every location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
    • WV4 is no longer collecting new imagery.
  • Increased Collection Capacity
    • WV3/4 feature 13.1-km swath widths (at nadir) with the ability to collect up to 680,000 square kilometer (sq km) of high-resolution data per day per satellite (though WV4 is dead now).
    • Improved control movement gyros translate into larger maximum contiguous collection areas per pass, with up to ~7,500 sq km of mono imagery and ~3,000 sq km of stereo possible.
