Abstract

DROUGHT is one of the major destructive natural disasters. However DROUGHT monitoring is very difficult task. Using GIS and RS in DROUGHT monitoring is more effective than traditional methods. We used two Landsat images for Mashhad area, one for a wet and the other for a dry year to calculate Normal Deficit Vegetation Index (NDVI).Comparing NDVI derived for the two years, we could detect DROUGHT effect on crop production in the area. The cultivated areas were separated from other areas using an image processing procedure and some field works. The derived NDVI for the area was classified into 10 classes.Another index was defined as percentage fraction of the area for each class of NDVI value in the whole area. This index enabled us to compare crop production for the two years. The results showed that NDVI was between 0.5 and 0.7 in wet year and vary between 0.1 and 0.4 in DROUGHT year. It was concluded that this method could be used as a basic method for DROUGHT monitoring system, if we prepare a reasonable data base of NDVI for a long period of time for the study area.
