Abstract

In order to evaluate the potentiality of satellite data in classification of Saline Soils a thematic mapper subscene of Hoze-Soltan area in Qom province, Iran dated september 1991 was analysed. The satellite image was evaluated qualitatively. Geometric registration of image data was implemented using ground control points which were taken with DGPS. The RMS error was calculated to be about a half-pixel (0.55m). Different IMAGE ENHANCEMENT techniques such as Band-Ratioing and PCA had been determined. 52 samples were taken random and systematically from topsoil and subsoiL The salinity parameters such as Electrical Conductivity (Ec) pH and soil texture of the soil samples were determined in the labratory. By specifying sample site on the geocoded satellite image, digital number (DN) relevant to the samples were extracted. Relationship between extracted DN and measured soil parameters were studied. According to the results, CORRELATION coefficient for TM4 and TM3/TM4 was higher than other origin and synthetic bands. Although, the highest obtained coefficient (r=0.54) is significant at the 1% level, but it is not sufficient in order to use in classification of saline soils.
