A method for the radiometric correction of wide field-of-view airborne imagery has been developed that accounts for the angular dependence of the path radiance and atmospheric transmittance functions to remove atmospheric and topographic effects. The first part of processing is the parametric geocoding of the scene to obtain a geocoded, orthorectified image(More)
An operational orthorectification solution in support of the combined geometric and radiometric processing of currently available imaging spectrometry data is presented. The described parametric geocoding procedure (PARGE) strictly considers the aircraft and terrain geometry parameters and uses a forward transformation algorithm to create orthorectified(More)
The airborne ESA-APEX (Airborne Prism Experiment) hyperspectral mission simulator is described with its distinct specifications to provide high quality remote sensing data. The concept of an automatic calibration, performed in the Calibration Home Base (CHB) by using the Control Test Master (CTM), the In-Flight Calibration facility (IFC), quality flagging(More)
Nearly all current imaging spectroscopy data are obtained by scanning airborne systems. The stability of such systems is always worse than that of spaceborne platforms. Thus, geometric distortions occur due to variations of the flightpath as well as of the attitude (given by roll, pitch and heading angles) of the plane. These distortions cannot be corrected(More)
The consistent end-to-end simulation of airborne and spaceborne earth remote sensing systems is an important task and sometimes the only way for the adaptation and optimization of a sensor and its observation conditions, the choice and test of algorithms for data processing, error estimation and the evaluation of the capabilities of the whole sensor system.(More)
The transition from film imaging to digital imaging in photogrammetric data capture is opening interesting possibilities for photogrammetric processes. A great advantage of digital sensors is their radiometric potential. This article presents a state-of-the-art review on the radiometric aspects of digital photogrammetric images. The analysis is based on a(More)
1. INTRODUCTION The radiative transfer code MODTRAN, version 4 (Berk et al., 1998; 2000) has been established as de-facto standard for the simulation of imaging spectrometry data and for quantitative modelling of the signal at the sensor level. The original interface of MODTRAN consisting of ASCII-file based inputs leads often to misunderstandings and(More)
