THE EFFECTS OF BAND-TO-BAND MISREGISTRATION ON MULTISPECTRAL CLASSIFICATION

Landsat-MSS data covering 636 x 457 pixels with band-to-band misregistration was digitally analysed for assessing the effect of misregistration on classification accuracy of land use/land cover mapping. Raw MSS data with band-to-band misregistration was geometricaly corrected using GCPs and a polynominal transformation of the first order. Subsequently, both raw and geometrically corrected data were analysed on a DIPIX system using a Gaussian maximum likelihood algorithm. Results indicate a substantial degradation in the classification accuracy due to mixed pixels which have remained unclassified owing to misregistration between bandpairs.
