Controls

Control	Description
Title	Type the title to display in the report.
Default	Click the button to display the default title for the report.
Use alignment project	Do one of the following: Clear the checkbox to compare selected points with an Alignment in the current project. Select the checkbox to compare the selected points with an alignment in a comparison project, then click and browse to the project that contains the alignment.
Alignment	Select the alignment to compare with the points.
Use terrain model project	Do one of the following: Clear the checkbox to compare selected points with a Terrain Model in the current project. Select the checkbox to compare the selected points with a Terrain Model in a comparison project, then click and browse to the project that contains the terrain model.
Terrain Model	Select the terrain model to compare with the points.
Use thickness terrain model project	You can compare points to an additional terrain model representing a previously constructed surface and report on the thickness between the two constructed surfaces. Do one of the following: Clear the checkbox to select the additional surface from the project. Select the checkbox to select the additional surface from another project, then click and browse to the project.
Thickness Terrain Model (Optional)	Select an additional constructed terrain model and report on the thickness between the measured points and the previously constructed surfaces. Use this to ensure that the thickness of the new surface is within tolerance.
Vertical Offset	Type an optional offset to be applied to the Terrain Model.
Upper Tolerances:	Type the acceptable height difference for the point to be above the terrain model. Height differences exceeding the tolerance display in blue.
Lower Tolerances:	Type the acceptable height difference (including a negative sign) for the point to be below the terrain model. Height differences exceeding the tolerance display in orange.
Maximum Standard Deviation:	Type the maximum acceptable standard deviation. Standard deviations larger than this value display in red in the reports statistical summary.
Minimum Number of Points:	Type the minimum number of points required for the report to be valid. If the number of points validated is less than this value the number of points validated will display in red in the report.
Chainage grouping	Group points based on similar chainages, then order the points in the group by increasing offset. Groups are separated by blank line. Do one of the following: Select the checkbox to enable the Width control and group points within the specified interval. Clear the checkbox to display all points in order of chainage along the alignment.
Width	Type the interval width for the Chainage grouping. (The distance along the alignment from the first point in the chainage group.)
Project start/end segments	Do one of the following: Select the checkbox to compute chainages for points beyond the start and end of the alignment by projecting the alignments first and last segments. Clear the checkbox to display blank for points beyond the start and end of the alignment. Note: Only straight segments can be projected.
	Move the selected item up in the Columns list.
	Move the selected item down in the Columns list.
OK	Show the comparison report.
Cancel	Cancel without generating the report.

The following columns are available for output in the report. Select the checkbox to include the item in the report.

Column	Description
Point Id	Unique point identifiers of the compared points.
Point Name	Name of the compared points.
Chainage	Chainage along the alignment to the location where the perpendicular 2D offset is computed. Note: Chainage equations are applied. Chainage is blank for projections at external deviations. Chainage is blank when points are not along the alignment.
Height	Height of the selected points.
Offset	Two dimensional perpendicular offset from the line.
Difference Height	The vertical difference in height between the point and the terrain model. Note: A positive height difference in blue indicates that the point is above the terrain model. A negative height difference in orange indicates that the point is below the terrain model.
Outside Tolerance	When the difference in height between the point and the terrain model exceeds the allowable tolerance, this is the amount that the tolerance has been exceeded by. Note: Values that exceed the upper tolerance are displayed in blue. Values that exceed the lower tolerance are displayed in orange.
Terrain Model Height	Height of the terrain model.
Thickness	The difference between the points height and the Thickness Terrain Model.
Thickness Terrain Model Height	Height of the optional thickness terrain model.

Notes

When using chainage groups, sorting by column will lose the formatting. Right click then select Refresh to restore the original format.
Height differences between points and the terrain model will be reported if the points are within the 2 dimensional extents of the terrain model.
Height differences between the points and the Terrain model displayed in blue or orange are out of tolerance.
Offsets with an asterisks are projected offsets.
To save the report, right click on the report view tab, then click Save.
If the average height difference exceeds either the Upper Tolerance or Lower Tolerance it is displayed in red.
If the standard deviation exceeds the Maximum Standard Deviation it is displayed in red.
If the points included in the report is less than the Minimum Number of Points the number of points displays in red.
This report is not available when using a 3d user coordinate system.
