Due to the rapid development in cities and suburban areas worldwide, and to the increase in the cost of maintaining a huge amount of geodetic landmarks, many governments feel the need to establish a modern vertical control system which could be used by practitioners of surveying, mapping and engineering, and that, at lower costs.<\/p>\n

\u00a0<\/p>\n

The GPS leveling that combines the ellipsoidal heights and geoid is a very necessary technology that will support the realization of future 3D positioning activities of our clients in their own countries, while reducing overall costs.<\/p>\n

To achieve this, ground, airborne and satellites gravimetric data are\u00a0required and used to calculate a geoid model of the Earth. The model can be imported in GPS or GPS software.<\/p>\n

The following Geodetic techniques are used for this application:<\/h2>\n
