Developing road line references with GeoPad |
Users can manually enter road lines or import road line files.
Normally a road line consists of three files.
- Plane geometry (.lin)
- Vertical geometry. Profile. (.prf)
- Cross slope. Camber. (.skv)
The GeoPad automatically checks the geometry when you enter road line files.
You can use road lines as a reference for setting out and control and also in the GeoPad editing mode for calculating:
- Coordinates along a line or for calculating section
- Offset from coordinates.

Sect.
|
The section in which the measured point is located.
|
|
Side
|
Side offset from the centerline to the measured point. A negative measure means that the point is to the left of the line.
|
|
dH1
|
The height difference between the measured point and the contiguous theoretical height in the measured point of the road line. (Right side of the road is positive offset and vice versa).
|
|
dH2
|
The height difference between the measured point and the resistant theoretical height in the measured point of the road line. (Left side of the road is positive offset and vice versa).
|
|
Slop.
|
The sloping in percent (%) at the measured point. Negative value is downward sloping from the road center.
|
|
V.Offs.
|
Vertical offset. Selected offset in height relative to the profile.
