Abstract EN

Digital Elevation Model (DEM) is one of the developed techniques for relief representation.

The definition of a DEM construction is the modeling technique of earth surface from existing data.

DEM plays a role as one of the fundamental information requirement that has been generally utilized in GIS data structures.

The main aim of this research is to present a methodology for assessing DEMs generation methods.

The DEMs data will be extracted from open source data e.g.

Google Earth.

The tested data will be compared with data produced from formal institutions such as General Directorate of Surveying.

The study area has been chosen in south of Iraq (Al-Gharraf / Dhi Qar governorate.

The methods of DEMs creation are kriging, IDW (inverse distance weight), spline, and natural neighbor.

This research used different software for processing and analysis such as ArcGIS 10.2, TCX and Civil 3D.

Two- sample t-test has been adopted to investigate the mean of elevation differences between compared datasets.

The results showed that the spline is the best method that can be used to build DEM in this study area.
