Abstract:
Elevations are used for many purposes such as contour maps so as design of
canals, drains, railways, roads and agricultural projects.
These elevations can be determined by a practical means, which is a tedious
job and time and money consuming.
The interpolation is one of the ways to estimate mathematically the height of a
point using the heights of neighbor points.
The aim of this research is to perform methods of interpolation in both geodesy
and Gis and to compare the results.
The main conclusion is that the use of GIS in interpolations is better than using
equations for interpolation as in geodesy.
