Atmospheric Correction
See the World’s true colors with Geomatica®! variations in the Earth’s atmosphere and terrain modify the spectral characteristics of satellite imagery. Atmospheric correction eliminates atmospheric and terrain effects and retrieves physical parameters of the Earth's surface, including: surface reflectance, emmisivity, and temperature. Such correction is especially important in cases where multi-temporal, multi-sensor, or multi-condition images are compared and analyzed.
The PCI Geomatics Atmospheric Correction package provides easy-to-use atmospheric correction for a wide variety of satellite sensors including: QuickBird, IKONOS, ASTER, SPOT, and Landsat. The package includes ATCOR2, for the correction of images in flat areas, and ATCOR3, for the correction of images in areas with rugged terrain.
LANDSAT 7 Imagery Before and After Atmospheric Correction
Features and Benefits of Atmospheric Correction with Geomatica:
- Easy-to-use processes are available in GUI, visual modeling, and command-line environments
- ‘Real’ reflectance values are obtained by removing or greatly reducing atmospheric and terrain effects
- Create razor-sharp imagery
- Perform multi-temporal, multi-sensor, and multi-condition comparisons
- Generate value-added products, such as Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI), and Leaf Area Index (LAI) vegetation indices
- Calculation of surface temperature
