Classification methods for Land Cover Mapping


Conclusions
The classification results show that the band-overlay image was considered accurate in terms of its spectral information. The classified results are used as a basis to compare the other results. The results from the HPF technique were not as good as band overlay. The slight changes in spectral characteristics were exemplified in both the classified image and the spectral response curves. Better classification results were obtained using the IHS image with the stretched panchromatic band. The mean brightness values for each land cover type are very similar to those associated to the band overlay image. Classification of the PCA image yielded poor results. The class signatures reflect the radiometric distortion resulting from the use of this technique. The classified image and spectral signatures resulting from the IMGFUSE image are very similar to those of the band overlay image because the radiometric information of the original data is maintained.
