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 November, we looked at Barra Airport in Scotland. For this edition of the 30-cm Color WorldView-3/4 Image of the Month we’re headed to Hungary to check out Pancho Arena, the world’s only soccer stadium (perhaps the only stadium in general) with a wooden roof.
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-4 image features Pancho Arena in Hungary, the only soccer stadium in the world featuring a wooden roof. The stadium is located outside of Budapest. An idea brought to life by the Doparum Architects firm, the 3,400-seat Pancho Arena stadium is home to league and tournament games. It was the idea of Prime Minister Vikto Orban, who was firmly focused on Hungarian architecture. The stadium was planned by Imre Makovecz and is in perfect harmony with the natural environment, with features such as the tree branch-like fan vaults. This 30-cm WorldView-4 image of Pancho Arena and its surroundings was captured August 3, 2017. This 30-cm WorldView-4 image has been processed by Apollo Mapping for improved perspective, clarity and colors. (Satellite Imagery © 2023 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.
