معالجة بيانات SRTM للتحقق من صحة خوارزمية kriging ومقارنة الاختبارات الإحصائية باستخدام ARC GIS 10.8

الملخص EN

The research aims to propose a mechanism for processing the digital elevation model (Srtm) through spatial interpolation by the kriging method, in order to address the distortions that occurred in the original product of the (DEM) model.

as well as to obtain credibility for the topographic surface, that is represented on the ground.

specifically, the treatment of the model (DEM) from the perspective of representing the phenomenon as it is in reality, and the research sought to remove distortions in the original model (Srtm) using traditional filtering methods, but its results are not acceptable, so spatial interpolation was it is the best way, by following a new mechanism that consisted of four stages from collecting information to the new topographical surface that was finally treated, as the research was able to complete a digital model with a surface free of distortions by (kriging) with an emphasis on the need to follow these steps to support the decision down to the best product.

the main objective of the correction is to extract a smooth topographic surface that is prepared for conducting analyzes such as hydrology, morphometric characteristics or the water network, and this applies to the standards of technical cartographic.
