Claim:
1. 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, the sensing device comprising: at least a first two dimensional sensor element, and a spectral filter, the sensing device being arranged to obtain subsequent multi-spectral images during said relative motion of the region of interest with respect to the sensing device, thus providing distinct spectral information for different parts of a region of interest using the first sensor element, the spectral filter and the first sensor element being arranged to obtain spectral information at a first wavelength or wavelength range using a part of the first sensor element and to obtain spectral information at a second wavelength or wavelength range using another part of the first sensor element, a second two dimensional sensor element, the sensing device being arranged to provide, using the second sensor element, an image of the region of interest for generating geometric referencing information to be coupled to the distinct spectral information, the second sensor element being adapted to provide a high-resolution image, providing detailed geometric information of the region of interest, and the first two dimensional sensor element and second two dimensional sensor element being integrated on the same substrate.
