| Abstract | This research attempted to develop and test a methodology for classifying the salt-affected
soils using Satellite Remote Sensing (SRS) and Geographic Information Systems (GIS) for
suggesting some appropriate recommendations.
The study was carried out in an area of Nakhon Ratchasima province of Thailand which
is known to be salt-affected. Digital image processing of Landsat TM acquired on Jan 10, 1994
and vector based GIS were employed.
Taking salt crust as criteria, Landsat TM with bands other than two and six was found
effective, to a greater extent, in classifying the extremely and moderately salt-affected area.
Integration of GIS was found effective not only for classifying low and potential saline area but
also for correcting such area misclassified as extremely or moderately salinity. Six classes of
salinity could be delineated. The confirmation of result with field check, existing salinity map
and soil analysis had proved it as reliable one.
The result showed that distribution of extremely and moderately saline area was
extensively under rice cultivation, although farmer could get very low or nil production from the
former class.
However, similar pattern of soil salinity was obtained from the study compared to the
existing map of 1989 prepared from Landsat MSS data at scale 1:250,000, the classification
result was found to show more details.
The study concluded with the remark that integration of GIS with digital image processing
of landsat TM was very effective for classifying and monitoring of salt-affected soils. |
