Abstract
In this present research mathematical model is built , this model has the
ability of using global positioning system (G.P.S) to compute the elevations with
high accuracy to use in mapping contour lines with contour interval 1m applied in
fabricating digital elevation model (DEM). Certain spot height are chosen by
means of universal standard, the measurements are mathematically analyzed using
general equations in geodesy to obtain acceptable accuracy to all engineering
works .
