Structure of a Digital Airborne Camera,ntation, taking into account MTF (modulation transfer function) and radiometric representation (noise, sky light), or also as an indirect image, because it can be represented as a Fourier transform extending over the entire area being observed (the reflected radiation can be interpreted as the sum of many two-dimensional spatial frequencies).

Data Processing and Archiving, line camera records each ground pixel three times. Using an array camera and the typical minimum forward overlap of 60%, a 2.5-fold amount of data compared to a sequence of non-overlapping images is produced; and in the case of larger forward overlaps to obtain smaller stereo angles, even greater quantities of data are created.

Introduction, the level of technology at each particular time. Continuous efforts have been made to employ the best technologies available in either the area of photographic technique or the methods of getting the camera airborne.

Calibration,ilm, these cameras were calibrated with regard only to image geometry and the limit of resolution of the lens. In the case of digital cameras, however, a complete calibration can be carried out at the system level, including effective resolution and spectral responsivity.

Data Processing and Archiving,lect several hundred gigabytes of raw data. This is largely irrespective of the technology used. For sets of stereo images that can be triangulated, a line camera records each ground pixel three times. Using an array camera and the typical minimum forward overlap of 60%, a 2.5-fold amount of data co
