Chapter 4 Analysis and reporting
This chapter describes the manifold analysis options of Amberg Tunnelscan. The work flow
and many settings are similar in most analysis types.
You may create a copy of any existing analysis by clicking on the analysis node and
select

from the context-menu. A new analysis is added to the same head-
ing, preserving the settings of the original analysis.
4.1 Analysis type Line scan
The analysis type
Line scan
compares measured point clouds measured in one construction
stages against the design data of the selected reference. Normally the analyses is used for long
measured tunnel sections under construction (E.g. Shotcrete Layer 2) or of existing tunnels or
shafts for as build measurements.

as analysis type. Enter a name for the analysis,
optionally add a comment and click
Next
.
2. On the second wizard page, select a
Reference construction stage
that will be used for all
axis-related calculations displayed in the diagrams. Optionally select
Additional construc-
tion stages for display
, whose design data will be used for graphical purposes only. Set
Deviation unit and format
and
Stationing mode
that you want to use in this analysis. If
necessary, you can change all these settings in the settings dialog later. Click
Next
.
3. On the third wizard page, you can select one construction stages as data source. The anal-
ysis will take into account all measured point clouds from the selected construction stages.
4. On the next wizard page, select a
