Refinement of spatial resolution multispectral remote sensing data.

摘要

Procedure for processing multispectral remote sensing data in which a) primary measurement data from remote sensing at least one primary measurement channel are used; b) data measurement side remote sensing from a secondary channel measurement used; c) at least one primary spectral range in which the incident radiation is captured by the data of primary measurement and corresponding to the channel primary measurement or one of the channels of primary measurement is narrower than a second spectral range in which the incident radiation is captured by the secondary measurement data; d) the first spectral range or ranges are first spectral content entirely within the second spectral range (VV); e) secondary measurement data are finer than the primary measurement data spatial resolution; f) a spatial range or partial range data side measurement is determined (ML, RL) the spatial distribution of the irradiance captured at data side measuring the degree of reflection or a magnitude equivalent radiation and transferred (F) to a corresponding spatial range or partial range of the primary data measurement, so that the spatial resolution of the primary measurement data is refined; g) is refined (ML, RL) the spatial resolution of the data of primary measurement taking into account a balance of at least a portion of the radiant energy or radiation power or a balance of a radiant magnitude equivalent to the energy captured by measurement data without modifying said refinement (F) the amount of radiant energy, the radiation power or the equivalent amount, data captured by the primary measurement of partial spatial range; h) measurement values ​​of the environment partial spatial range data primary measurement to calculate a distribution of the magnitude recorded by means of measurement data within the partial space range are used, corrected (Q) said spatial distribution of data primary measurement with refined resolution by data primary measurement of the partial spatial range, so that abrupt changes of the magnitude captured caused by the refinement at the boundary of the partial spatial range or produced without reducing environment using the measured values ​​of the environment, thereby maintaining the spatial balance across the partial area.
