Abstract

A study was conducted to determine the capabilities of the successive numerical LANDSAT data for assessment and monitoring of soil SALINIZATION. KASHAN plain with 7220Km2 of area, which is located on an arid zone of the central part of IRAN, selected as the site of investigation. It seemed to be a region prone to DESERTIFICATION processes. Two sorts of LANDSAT data: MSS (1976), TM (1998) and the supplementary information such as the soil and geo maps, surface and subsurface water data were collected.After preprocessing, the images were classified on the base of the field and subsidiary data by four degree of salinity. Incorporation of the PCA12, PCA34 and NDVI in MSS and the TM4, PCAS7, PCA123 and NDVI in TM data showed the best results. The classification performed by the maximum likelihood algorithm. Accuracy assessment was performed on the base of another category of field data and showed 75% and 82% of overall accuracy for MSS and TM respectively.Merging and processing the whole data and maps showed that 7.5% of non-saline parts of region, has been changed to medium to high saline, and in the same time, the size of KASHAN salt lake has decreased 1.5% of total.On the basis of the results, it would be expressed that even though MSS and TM data have not the same image properties; important information could be extracted by comparing their accurate classified maps.
