Characteristics of New Generation of Digital Aerial Cameras



CONCLUSIONS
The emergence of the new generation of digital aerial cameras is a consequence of the new technologies that have become available for digital imaging. A ‘paradigm shift’ in photogrammetric operations does appear to be occurring, due to the availability of multiple overlapping images which lead to high accuracy and more reliable information extraction with greater efficiency. As well, with the acquisition of multispectral images, the automatic extraction of thematic information from images required for digital mapping and GIS data collection should be more easily achievable. A next step in automation in photogrammetry may be the development of procedures for computing orthophotos in real-time during flight. This requires significant software developments and computing power, but there are certainly moves to achieve it.

While the aerial film photography is not yet finished, the future will no doubt see improvements in the quality and capabilities of digital aerial cameras and a reduction in costs. This will lead to their greater acceptance by users and a decline in the use of film images. The timing of these developments is hard to estimate, but it can be expected that the next decade will see a rapid transformation to digital aerial imaging, with much higher throughput and greater economies in the production of map products.
