PARGE® Image Rectification

Parametric Geocoding & Orthorectification for Airborne Optical Scanner Data.

PARGE® is the orthorectification and direct geocoding software for airborne optical scanner data. It performs an ortho-rectification of line scanner imagery using a digital elevation model on the basis of high precision flight parameters such as GPS position and attitude angles. Using accurate digital elevation models and optional ground control points, sub-pixel geometric accuracy is achieved. The program is suited for the correction of all kinds of airborne scanner imagery and is optimized for airborne hyperspectral instruments.

The software offers these key advantages:

  • direct parametric geocoding & orthorectification,
  • a semi-automatic, ground control points-based boresight calibration procedure
  • optimization for imaging spectroscopy (hyperspectral data)
  • a workbench-style graphical user interface
  • open internal data format and programming interface
  • wide variety of resampling options
  • support for raw-geometry based processing chains
  • automatic mosaicking
  • direct link to atmospheric correction package (ATCOR-4)
  • customer-oriented software customization
