PARGE

PARGE is an orthorectification and direct geocoding software for airborne optical scanner data.

PARGE performs an orthorectification 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 accuracy is achieved. The program is suited for the correction of all kinds of airborne scanner imagery and is optimized for airborne hyperspectral instruments. Directly supported sensors so far are: HyMap, Probe-1, AVIRIS, CASI, AISA (Eagle), MIVIS, Deadalus ATM, PHILLS, APEX, Samson, Resonon-PIKO, and HYSPEX.

  • Sub-pixel accurate geometric calculation and DEM intersection

    Boresight alignment of sensor system based on ground control points

    Optimized choice of resampling techniques.

    Sophisticated graphical user interface for all functions with integrated on-line help system

    Side output of pixel scan geometry for BRDF research and atmospheric correction

    Tools for parameter filtering and correction,

    Support for batch processing through IDL scripts.

  • Parametric geocoding and orthorectification

    A semi-automatic ground control point based boresight calibration procedure

    Optimisation for imaging spectroscopy (hyperspectral)

    A workbench-style graphical user interface
