Change Detection Study Of Al Razaza Lake Region Utilizing RemoteSensing And GIS Technique

Abstract

Remote sensing techniques are now widely used for environment studies, surveys
and monitoring. It became a need to study Razaza lake and the surrounding areas
especially when the Antiquities Authority of the Ministry of Tourism announced,
that the discovery of the effects under the waters of Lake Razzaza in Karbala
province. The aim procedures carried out in this study, the first classified the study
area by using unsupervised classification method to produce the land cover and land
use ,deriving the elevations as a vector layer using TIN for the whole surrounding
region of lake, the second part, the output is a continuous surface to be created by
applying Kriging interpolation, the third step, obtaining maps of contour lines also
used to show lines of constant density or brightness by implementations the contour
lines , converting the result of interpolation method to a vector values that can be
calculated, then the implementation of the classified process and calculating the area
around the lake, all these steps are done by using ArcGIS. Finally a classification
process for the same scene on a different date is applied and then compare it with
the first scene using ERDAS.
