Atmospheric Compensation

Atmospheric Compensation – DigitalGlobe AComp Pre-Processing

DigitalGlobe’s Atmospheric Compensation (AComp) is an algorithm that removes haze and vapor particles and is used to correct and clarify high resolution panchromatic and multispectral satellite images (including SWIR bands) under diverse atmospheric conditions. AComp cuts through haze providing accurate analysis to support feature extraction applications from high-resolution satellite imagery including WorldView-2, WorldView-3, WorldView-4, GeoEye-1, WorldView-1, QuickBird, and IKONOS satellites and image data from other satellite sensors.

AComp can greatly benefit industries including oil and gas, agriculture, defense and intelligence, mining, and disaster relief efforts.

DigitalGlobe offers AComp pre-processing at no additional charge.

What AComp does:

  • Minimizes haze effects while preserving the full spectral information in reflectance pixel values
  • A fully automated process, available on the entire DigitalGlobe constellation
  • Significantly improves the accuracy of image mining and machine learning algorithms
  • Provides normalized surface reflectance values across every pixel
  • Facilitates cross-sensor processing, by enabling comparison across DigitalGlobe and other satellites
  • Removes significant error in the comparison of images over time
  • Compatible across both panchromatic and multi-spectral images
