Abstract
The Digital Modular Camera (DMC) is the new digital aerial camera system of Z/I Imaging. It is based on CCD areal array sensor technology and provides a very high interior geometric stability. According to its modular design, more than one individual camera module can be tied together, resulting in a large field of view of the camera. The DMC high end configuration consists of four panchromatic and multi-spectral modules, respectively. The four panchromatic modules are arranged in a matrix, two across track and two along track and have their optical axes looking downwards in a slightly divergent set-up so as to reach a large ground coverage. A post-processing procedure serves to transform the four individual images into one virtual image which can be considered being of a normal central projection. The multi-spectral modules are arranged around the panchromatic modules acquiring nadir looking views. Their imagery has the same ground coverage as that of the virtual image but a reduced resolution. The paper deals with the geometric accuracy potential of the DMC from the photogrammetric point of view. The system structure is outlined. Factors which influence the mapping accuracy are analysed and discussed. An outlook on future applications concludes the paper.
