Edit Heights

In this dialog box, you will see the horizontal alignment of the barrier in the figure to the right and the vertical alignment of the barrier in the lowest figure. The scale of these figures will be adjusted to make the most out of the space. The lowest figure has profile numbers along the horizontal axis and altitude above sea level along the vertical axis. In the figure to the right, the barrier has the same orientation as in the map.

The first time we get into this dialog box, the barrier is specified with an elevation of 0 m (altitude). There are barrier points at the start and end of the barrier together with all horizontal break points (all points on the polyline defining the centerline of the barrier). For each barrier point, there is a height calculated from the terrain model.

Barrier points

Basically, a barrier point is a point where the barrier has a break either in the horizontal or vertical direction. In addition, the barrier’s start and end points are defined as barrier points. The functions in this frame allow the user to change the barrier points. The profile number of a barrier point is the distance along the centerline of the barrier from its start point.

It is important that feature codes and groups etc. are correct in the terrain model before terrain heights are fetched.

The terrain height in a point may in theory become as much as 1 m wrong if the equidistance is one meter. On detailed design, one should therefore check the absolute heights.
