Ground geometry¶
The data relevant to the ground geometry is necessary for the definition of the topographic profile of the ground. The environment for the management of the ground profile is the following:

Data entered by coordinates
Enter the coordinates of vertices which define the profile with regard to a fixed reference system. The vertices must be entered from downstream to upstream in terms of x-z coordinates. The coordinates must be expressed in m. The inclination of the upstream and downstream profile must be also entered. It is possible to view the numbers of the vertices.
Data entered by angles and distances
N.B.: The insertion of the data in terms of angles and distances is only an integrative – not a substitute – instrument of the insertion of the vertices in terms of coordinates. In fact, also after the insertion of the angles and distances it is necessary to click on the Generate coordinates button, which lets you go back to the window relevant to the vertices.
Seeing the importance that the insertion of the data in terms of coordinates of the vertices has, some specifications must be made.
You can refer to the following figure:
We report, for the sake of completeness, a guide figure for the insertion of the geometrical data by angles and distances.
