A Detailed View of the Ground with 30-centimeter Satellite Imagery

Which airline is that?

Satellite imagery at 30-centimeter resolution provides the clearest, most detailed view of the ground from space. See sample imagery to find out for yourself.

If you use commercial satellite imagery to map, monitor or assess situations, materials, or infrastructure, you are probably accustomed to 50-centimeter spatial resolution. Now, with the resolution relaxation from the United States Government that went into effect on February 21, 2015, you have access to an even clearer view of the ground with 30-centimeter resolution commercial satellite imagery.

With 30-centimeter resolution you have greater detail for imagery analysis, and more information for mapping features on the ground. The detail available is unseen in any previous commercial satellite image, setting the new standard for commercial resolution.

You can see the visual quality difference between this 30- and 70- centimeter commercial satellite image of the Kalgoorlie Mine in Australia.
With more than 2.5x the pixel density of 50cm data, and 5x the pixel density of 70cm data, the visual quality difference of 30cm commercial satellite imagery is stunning.

Commercial satellite imagery at 30 centimeter resolution is now competitive quality to your aerial imagery and is available globally.

You can use this aerial-competitive imagery for a variety of purposes such as mapping your country, monitoring infrastructure, managing natural resources, and more. Plus, since many countries impose restrictions on aerial imagery, or in some cases locations are difficult or unsafe to reach with a plane, the global reach and quick access of satellite imagery may be the only way you can get the true conditions on the ground at 30-centimeter resolution.

The higher-resolution of 30-centimeter commercial satellite imagery aids you in more accurate and automated land use and land cover mapping, feature identification, and change detection. In the end, this means that you’ll have a better inventory of your infrastructure and resources, both public and private, and a better understanding of what is changing in your country.

So, what can you actually see using 30-centimeter satellite imagery? Here are some examples.
