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! Last month we were in China with a look at one of the world’s largest amusement parks, and for this 30-cm Color WorldView-3/4 Image of the Month we head to one of the Middle East’s most historic cities, Beirut, Lebanon.
Beirut is considered one of the world’s most ancient cities with evidence of human inhabitants for at least the past 5,000 years. We selected the three images here for, one, the bright colors, especially the blue roof of the mosque, and two, for the small features that can be seen such as rocks, debris and old building walls. These images of Beirut were collected on September 30, 2014 by the 30-cm satellite, WorldView-3; and they have been processed by Apollo Mapping for improved colors and clarity.

If so, send us an email at sales@apollomapping.com.
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.
- Per US government regulation, all WV3 SWIR orders are produced at a maximum resolution of 7.5-m. CAVIS bands are not available for purchase at this time.
- 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, WV3/4 will each be able to image every location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
- 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.
- 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.
