DigitalGlobe and Airbus Imagery Products Now Delivered in Reflectance

Starting immediately, we are happy to announce that all multispectral imagery products offered by both DigitalGlobe and Airbus can now be delivered with pixel values in reflectance. Traditionally, satellite imagery has been delivered with unit-less pixel values representing the number of photons hitting the on-board optical sensors, also referred to as digital numbers. While these are a good proxy for surface reflectance, for many spectral studies that require comparing pixel values across time and space, digital numbers will not suffice.

For these spectral studies, scientists have traditional completed atmospheric corrections (ATOC) which convert unit-less pixel values into radiance and/or reflectance. Now, you can have your next multispectral imagery order converted to reflectance using DigitalGlobe’s and Airbus’ proprietary processing techniques which produce more reliable and accurate results in a fraction of the time. As an added bonus, their correction services are free!

These atmospheric correction services can also improve image quality by reducing atmospheric haze, thereby increasing the number of archive options available to you in cloudy regions.

If you have any questions about DigitalGlobe’s and Airbus’ new atmospheric correction services, please send us an email at sales@apollomapping.com.

    Could you please provide us the demo images from DigitalGlobe (before and after)? We will process it with our software COOL to show the dehaze result.

    Could you provide us the demo images from the DigitalGlobe for dehaze testing?
    We will process it with our COOL software to see the differences. Thanks
