This research aimed for using Geographic Information System (GIS) in producing
Digital Elevation Model (DEM) for Dimas District, By applying various methods: Spatial
Analyst, Geo Statistical Analyst, Triangulated Irregular Network (TIN), and interp
olating
DEM from contour lines.
The study showed that the best methods for interpolating DEM is Kriging method,
Which interpolated an evaluated surface for scattered points which had (Z values) whether
they were closed or scattered from each other. And (TIN) method which required less area
on hard disc to be stored comparing with other methods, and it's perfect for representing
surfaces in wide areas, Also generating DEM from contour lines produced DEM which had
very accurate representing for surfaces.
