PARGE - Background Information

Major Achievements

The major achievements of the PARGE application are:

Development History

In 1991, an AVIRIS-based campaign initiated the research in hyperspectral data processing in Europe and also in Switzerland. In the course of these activities, researchers at the Remote Sensing Laboratories of the University of Zurich started looking into the geometric problem of airborne imaging spectrometer data. First successful orthorectification of AVIRIS data over rugged terrain in central Switzerland was shown by Peter Meyer [1994]. In 1997, these initial ideas were taken over by Daniel Schläpfer after the demand for such a program was given. An operational environment was then implemented for the parametric orthorectification of airborne scanner data, wherefrom the first first version became available in 1998 named PARGE (PARametric GEocoding).

The work was initially supported by the Swiss National Science Foundation (Nationalfonds). Later, the Remote Sensing Laboratories of the University of Zurich supported the further development. In spring 2000 'ReSe Applications Schläpfer' was founded for further development and commercial distribution of PARGE and related software under license of the University of Zurich. The software is currently actively maintained and developed by Daniel Schläpfer (ReSe Applications).

Current Status



The application has been fully developed by D.Schläpfer using IDL (Exelis Inc.). The project started in 1997 as part of a PhD work and was initiated by the experimental approach for AVIRIS data, which had been developed by Peter Meyer at RSL. At this point it was the best to redo the whole application from scratch in view of a fully operational package. The maintenance and updates to the software are now done by 'Rese Applications Schläpfer'.

Substantial input to the development was given by the DLR Oberpfaffenhofen (Germany), by various students at RSL, and by the PARGE end users.

The operational testing and further development of the software is done in close collaboration with PARGE end users.
