DigitalGlobe Satellite Imagery
If you want the sharpest satellite imagery in the world, then you should harness the power of DigitalGlobe satellite imagery.
To give you a ballpark figure:
Each pixel in a Worldview-3 image is about the size of home plate on a baseball diamond. That’s about 31 cm.
So instead of being far-sighted, you can see a better and clearer world with some of DigitalGlobe’s products.
DigitalGlobe’s cutting-edge high-resolution satellite carves out ridiculously crisp imagery at 31 cm. In 8 spectral bands, the world all of a sudden becomes clearer.
So how good is DigitalGlobe imagery?
There are a couple of ways to find out:
Tap into DigitalGlobe’s Open Data Program supports disaster recovery for any sudden major crisis or event. For example, DigitalGlobe has assisted in fighting forest fires, assessing earthquake damage, and hurricane relief. As part of DigitalGlobe’s Open Data Program, they release imagery into the public domain under a Creative Commons 4.0 license which may include crowdsourced damage assessment.
Further to this, DigitalGlobe has product samples available for different parts of the Earth. For example, sample imagery products are more available for Rio de Janeiro (Brazil), Stockholm (Sweden), and Washington DC (USA).
If you are just looking to purchase Worldview imagery scenes, the Worldview Viewer application gives you the option to preview and find images in the archive.
DigitalGlobe also provides base maps, analytical services, precision aerial, maps API, and various other products and services.
IKONOS, Quickbird, and GeoEye Imagery
A satellite marvel in 1999, IKONOS was the first satellite granted a commercial license in America. However, IKONOS-1 never made it to space. IKONOS-2 did and was renamed simply “IKONOS”. IKONOS delivers 4-meter multispectral (RGB, NIR) and 1-meter panchromatic imagery.
The versatile and cost-effective QuickBird satellite acquires high-resolution optical imagery seamlessly from the world. Even though it was decommissioned in 2015, you can dig into its archive images at a cost. While panchromatic images are 61 cm resolution, their multispectral bands (RGB, NIR) are 2.4 meter
Finally, DigitalGlobe acquired GeoEye which is so sharp that ecologists have used it to track the animal population. Google had its logo on the side of the rocket and has exclusive access, so there’s no coincidence it is a base map imagery in Google Maps. GeoEye imagery is 41 cm for panchromatic and 1.65 meters for multispectral (RGB, NIR).

GeoEye consists of 5 spectral bands (panchromatic, blue, green, red, and near-infrared). While the panchromatic band has 0.41 meters resolution, the blue, green, red, and NIR bands are 1.65 meters.
MDA Acquires DigitalGlobe
The recent purchase of DigitalGlobe from MDA turns a new leaf in the era of space imaging.
As you may not know MDA, MDA owns and operates Radarsat-2.
And this will include 3 additional satellites from the Canadian Radarsat Constellation Mission.
Now, technical users can access another untapped resource like synthetic aperture radar for even more rigorous analysis.

Hello, the product samples for Rio de Janeiro (Brazil), Stockholm (Sweden) and Washington DC (USA) are available at DigitalGlobe website. But, I could not identify the satellite name that provided these images.
You can test out their imagery in the samples section of their website – https://www.digitalglobe.com/samples
Hi, appreciations to your good work. How can I download Worldview-3 imagery? I could not find it through your article.
There’s publications involving LiDAR and infrared so those would be the two components you’d be looking for. However, most LiDAR is airborne so that might a big more challenging. You may get lucky in our free LiDAR sources – https://gisgeography.com/top-6-free-lidar-data-sources/
Hi, from which satellite and how can I get images for archaeological research and buried cities under the soil?
