Appendix B – Choosing the Correct Lateral
Offset
The PaveScan RDM system is designed to view all data looking up-station and increasing distance.
Paving direction and collection direction are irrelevant. This must be kept in mind when configuring the
system regarding referring to the direction of the Lateral Offset side. This is done to remove all relative
information and display all data as an actual one-way direction.
Choosing a Lateral Offset Reference
Facing the direction of increasing distance, choose a lateral reference that all the measurements can be
associated with. Enter this in the “Lateral Reference” line in project info. This reference must be used for
the entire project.
The side of the Lateral Offset Reference is always on the side of the cart (left or right) RELATIVE to
facing up-station. This is regardless the directly of paving and the direction of collection.
Choosing a Lateral Offset for a File
During collection of a file, the distance to choose for the lateral offset should be the distance from the
lateral offset reference to the center of the cart. When this is done, and the cart is positioned at the start of
the line and looking in the increasing distance direction.
The Lateral Offset direction is the position (left or right) of the cart relative to the reference line when
facing the increasing distance direction.
