Saline Soil Detection Using Satellite Remote Sensing

Abstract

Nowadays, the soil salinity is becoming a more serious environmental problem, especially in the irrigation areas. The situation must be closely followed-up to provide the supporting data for urgent decision making, restoration, and improve the soil and land. The effectiveness of saline soil detection is depending on the proper application of imagery with different spectrum and also to transform and classify before interpretation. Besides, the detection and assessment of the changes at present and the past is capable to figure out the change of nature as well as the scale of change. This analysis pattern is conducted through the up-to-date equipment and relied on the specialist.
The best saline soil detection results can be obtain after the merging of satellite remote sensing data, field study data and the laboratory data. The Geographic Information System (GIS) is suitable for data manipulation in terms of detecting the scale, time, source and structure of the data. It is very challenging for researcher to properly analyze the specific indicator of Saline Soil. Hence, the satellite remote sensing technique and the ground survey have been applied to effectively detect the salinity it is low cost and accurate.
