Abd EI Magid Ali EI Mobarak


Abstract:

Landsat 5 Thematic mapper image (173/50) dated 21 september 1985 was used in this study. The images were displayed on a high resolution screen using computer compatible tape (CCT). The methodology followed to classify the images is the photomorphic unit approach. Three bands 2, 3 and 4 were used to make false colour composite (FCC) and all bands 2, 3, 4, 5 and 7 were used to calculate the. percentage of information contained in each band. Six units were identified from the FCC and three classification techniques were employed and a comparison between them was done also. The results showed some differences between the three techniques.
