Refinement of spatial resolution of multispectral remote sensing data

摘要

The method involves using first measurement data of a first measurement channel and second measurement data of a second channel obtained by remote sensing. A first spectral range, in which incident radiation is detected by the first measurement data, and which is associated with the first channel, is narrower than a second spectral range in which incident radiation is detected by the second measurement data. The first spectral range is fully contained within the second spectral range. The second measurement data have, locally, a finer resolution than the second measurement data. In a local range of the second measurement data, a local distribution of a beam density in the second data, a degree of reflection or an equivalent radiation parameter is determined. This is transmitted to a corresponding range of the first data, taking into account the measured radiation energy or equivalent parameters, so that the local resolution of the first data is refined. Independent claims are also included for: (1) apparatus for carrying out the method; (2) a computer program; (3) a data carrier or computer system.
