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 July, we looked at California’s 2023 Superbloom. For this edition of the 30-cm Color WorldView-3/4 Image of the Month we’re headed to Monaco to take a peek at the amazing Stade Louis II.
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 Monaco’s Stade Louis II complex. The stadium primarily hosts football (soccer for our American readers) games and is home to both the Monaco National Football team and AS Monaco. Many other events are hosted here as well, as the stadium includes the Salle Gaston Médecin, an indoor sports arena located underneath Stade Louis II. Various competitions, including swimming, volleyball, weightlifting, gymnastics, and fencing are hosted at the Salle Gaston Médecin. The stadium can seat 18,523 people. This capacity, while comparatively small among European sports centers, could hold nearly half of Monaco’s total population. The facility also has a noteworthy parking garage that houses 1,700 spaces! We wish venues in the local Denver area were as well equipped! ☺ Stade Louis II was originally constructed in 1936, and was commissioned by Prince Louis II of Monaco, after whom the stadium is named. In 1985, the stadium was rebuilt by Prince Rainier III, the grandson of Prince Louis II. The stadium’s reconstruction used 120,000 cubic meters of concrete, 9,000 tons of iron, and 2,000 tons of steel. The stadium stands on land that was reclaimed from the Mediterranean Sea and is located on the southern edge of the state of Monaco, right near the shore of the Mediterranean. It is a convenient walking distance from the Gare de Monaco-Monte Carlo, and can be toured Monday-Friday between April and September. This 30-cm WorldView-3 image was captured on August 1, 2021. It gives a good perspective to the size of Stade Louis II and shows the jewel blue waters of the Monaco coastline. This 30-cm WorldView-3 imagery 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.
