Analysis of Reconnaissance Imagery Acquired in Different Spectral Ranges of the Electromagnetic Spectrum

Technological advances and an increased demand for reconnaissance images acquired in different spectral ranges of the electromagnetic spectrum for Imagery Intelligence have contributed to the construction of a reconnaissance pod system DB-110. The main aim of this article was a comparison of pictures acquired in the visible, near-infrared and mid-infrared ranges. The analyses was carried out by comparing the general construction and statistical data of the images, and their relevance for the evaluation of the terrain, the characteristics of individual objects, conducting various types of spatial analyses and the usefulness of the process of image interpretation. It was found that the images from the electrooptical scanner are a better source for the image interpretation process in identification terms. The thermal images enable the detection of objects that are not detectable in the images from the visible and near-infrared spectral ranges of the electromagnetic spectrum.
