Theory and reality of direct georeferencing in national coordinates

ISPRS Journal of Photogrammetry and Remote Sensing, 2008
This paper focuses on the transformation of the sensor's exterior orientation parameters obtained by direct georeferencing (DG) to national reference frames and their subsequent projection for mapping purposes. The required steps are explained and the emphasis is put on the minimization of distortions arising from the curvature of the earth and the ...

Direct georeferencing of airborne pushbroom images

Journal of the Chinese Institute of Engineers, Transactions of the Chinese Institute of Engineers,Series A/Chung-kuo Kung Ch'eng Hsuch K'an, 2015
Direct georeferencing (DG) for orthoimage production based on collinearity equations has emerging as a standard photogrammetric operation. In this paper, the basic idea of DG is realized and refined with 19 self-calibration parameters for rectifying airborne pushbroom hyperspectral images collected using the intelligent spectral imaging system (ISIS ...

Approximate direct georeferencing in national coordinates

ISPRS Journal of Photogrammetry and Remote Sensing, 2006
Abstract Direct georeferencing has gained an increasing importance in photogrammetry and remote sensing. Thereby, the parameters of exterior orientation (EO) of an image sensor are determined by GPS/INS, yielding results in a global geocentric reference frame.
