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 January, we reveled in the impressiveness of Stadion Batarija in Croatia, considered to be one of “The World’s Greatest Sporting Arenas.” For this edition of the 30-cm Color WorldView-3/4 Image of the Month, we admire Gospin Dolac Stadium in Imotski, Croatia.
This month’s 30-cm WorldView-3 images feature Gospin Dolac Stadium in Imotski, Crotia. Considered to be one of the most original and attractive stadiums in the world, this stadium was built in 1989 on steep cliffs within a stone’s throw of local historical sites. People who sit in the stadium can see the nearby forest, mountains, Lake Modro and an old observation tower near the football field. Gospin Dolac is the home stadium for the Imotski football club and can accommodate 4,000 spectators, although the number of curious tourists visiting the stadium tends to be much more. The stadium is named after a nearby church with quaint houses in the town stacked behind the stadium on one side. In fact, the stadium was named one of the top 10 most beautiful stadiums in the world by the BBC in 2017. The 30-cm WorldView-4 images of Gospin Dolac Stadium and surrounding community were captured November 4, 2018. These 30-cm WorldView-4 images have been processed by Apollo Mapping for improved perspective, clarity and colors. (Satellite Imagery © 2024 Maxar Technologies)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:
- 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.
- 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).
