طريقة مبتكرة لإيجاد ارتفاعات النقاط بدقة عالية لاستخدامها في انتاج الموديل الرقمي للأرض (DEM)‎ بواسطة منظومة GPS

الملخص EN

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
