Abstract
A sensing device for obtaining geometric referenced multi-spectral image data of a region of interest in relative movement with respect to the sensing device, includes a first two dimensional sensor element and a spectral filter. The sensing device obtains subsequent multi-spectral images during the relative motion of the region of interest with respect to the sensing device, thus providing spectrally distinct information for different parts of a region of interest using different parts of the first sensor. A second two dimensional sensor element, using the second sensor element, provides an image of the region of interest for generating geometric referencing information to be coupled to the distinct spectral information.
