The Tunisian Land Information System (TLIS)

Authors: Abdelmajid Ben Hadj Salem
Comments: 63 Pages. In French

To celebrate the launch of the "Tunisian Land Information System (TLIS)" project, we would like to recall some of the history of Tunisian geodesy since its inception, and describe in detail the terrestrial and spatial geodetic systems that have been used since then.

The Transformation of Bursa-Wolf of Seven Parameters

Authors: Abdelmajid Ben Hadj Salem
Comments: 9 Pages. In French

In this note, we present the Bursa-Wolf seven-parameter transformation from one geodetic system to another, showing how to determine the 7 parameters by the method of least squares and calculate them numerically.

Note on the Resolution of the Equation β(φ)=Y Used in Geodesy

Authors: Abdelmajid Ben Hadj Salem
Comments: 9 Pages. In French

In this note, we give a method to resolve the equation β(φ)=Y used in geodesy, where β(φ) is the length of the arc of the meridian of an ellipse or an ellipsoid from the equator to the point of geodetic latitude φ.
