The first step of this study consisted of a visual analysis of Landsat images including contrast and colour analyses. This analysis helped us to Iocate four subimages (256 x 256 pixels). The processing of Landsat digital data consisted of several parts: (a) selection of the optimal channels for a multispectral classification of Landsat digital data: (b) determination of the thresholds, by different methods (frequency histograms, radiometric transects and radiometric-charactenzation of the

The computer map was used as a basis for mapping the soil surface conditions of south-western Sinai (Egypt).
