Multiband aerial imagery in remote sensing is a technology used more and more widely in present days. It can excellently be used in research fields where there is need for high spectral resolution images in order to obtain adequate level results. At present, data collection is of a much higher level than processing and use. As the technical development of sensors is followed by a significant delay in data processing methods and applications, it seems reasonable to refine processing methods as well as to widen practical uses (agriculture, environmental protection). In the year of 2004, a new examination method based on fractal structure was introduced, which, according to our experiences, has made more accurate spectral measurement possible as opposed to other techniques. The mathematical process named spectral fractal dimension (SFD) is directly applicable in multidimension colour space as well, making thus possible to choose new examination methods of multiband images. With the help of SFD, it is possible to obtain more useful data offered by high spectral resolution, or to choose the bands wished to process applying different methods later.
