Change detection study of Al Razaza lake region utilizing remote sensing and GIS technique

الملخص EN

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.
