30-cm Color WorldView-3 Image of the Month – Tunis, Tunisia

Every time we look at WorldView-3 (WV3) imagery, we are blown away. And we hope you are equally impressed with the data! In February, we featured imagery from an Italian mountain town and this month we move across the Mediterranean with a peak at one of Africa’s most historic cities, Tunis, Tunisia.




What really caught our eye this month were all of the amazing geometric shapes we could spot from overhead in Tunis. From circles, to crescents, to stars, the city seems to have it all. Plus we love the purple color you can see in one of these images towards its western side – can you find it too? These 30-cm WorldView-3 images were collected on July 7, 2016.

PLEASE NOTE: Effective May 2016, WorldView-3 prices dropped again! Are you interested in finding out more about these price drops? If so, send us an email at sales@apollomapping.com.

WorldView-3 launched in late 2014 and it is the most advanced satellite the commercial marketplace has ever had access to. Here are a few of the features that really set it apart from the competition:

Improved Resolution

  • Higher resolution means you can see more detail in WV3 imagery.
  • Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m SWIR and 30-m CAVIS 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 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 has no rivals for its enhanced positional accuracy.

Daily Revisits

  • At 40 degrees latitude, WV3 will be able to image each location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.

Increased Collection Capacity

  • WV3 features a 13.1-km swath width (at nadir) with the ability to collect up to 680,000 square kilometer (sq km) of high-resolution data per day.
  • 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.
