Insert Cross Sections (InsCro)
Type: Interactive Application
Creates cross section lines from LiDAR surface data and allows viewing the cross section line profiles. New lines may be digitized or existing lines may be selected. Existing lines may be draped to the surface or displayed as they exist without draping. There are options to automatically add points at breaks in the surface.
Once a cross section line has been digitized or selected, it is displayed in a 3D viewing window with optional stereo capabilities. Multiple passes may be taken on each cross section line using different point filter options. All passes will be displayed in the cross section viewing window.
A typical workflow for using Insert Cross Sections to place new cross section lines is as follows:
| 1. | Start VrOne and open a .vr file containing VrPoints. |
| 2. | Start Insert Cross Sections application. |
| 3. | Select "Enter params" and make sure draping parameters are correct and passes are set up. |
| 4. | Digitize a two point line across the area where you would like a cross section line recorded. |
| 5. | Cross section view window is displayed. The pass companion window enables Save buttons for each pass processed. |
| 6. | Examine the cross section(s) in the view window and determine which one you would like to save. Use the mouse wheel to zoom in and out. The cursor will track the cross section line and points by default, press the Del key to toggle tracking off. |
| 7. | When you are ready to save the cross section line to the workspace, press the Save button next to the pass you would like to record. |
This application may also be used as a quick cross section viewing tool by using the above steps, but skipping the last one where the cross section is saved. You may continue to work in the main VrOne window while the cross section is displayed, and the cross section view cursor will follow your movements in the main graphics window.

Set the parameters for each pass. Passes are used to display multiple versions of the same cross section line draped to different sets of points The following dialog is displayed when this button is selected:
Up to five passes may be taken on the cross section line. Each pass may use filters to define a unique set of VrPoints. This allows for quick comparison of profiles between different data sets.
Pass Parameters
Unless otherwise noted, any empty pass parameter behaves as a wildcard.
On
Determines if this pass is used. Only passes that are on are processed and displayed in the view window.
Auto record/re-record line
If on, this pass will be automatically saved
Save line layer
Specifies layer to which to save cross section line. -1=Same as identified line, or xx if line is digitized. (where xx = Pass number)
Save line width
Specifies width to assign to cross section line. -1=Same as identified line, or 1 if line is digitized.
Point classifications
Defines point classifications. A number line may be used. Point classification range: 0-31
Sensor number
Specifies sensor number. number line may be used. Point classification range: 0-31
Flight number
Specifies flight number. A number line may be used. Point classification range: 0-31
Point return number
Specifies point return number. Select a point return number from 1-5 or All.
Use keypoints?
Specifies whether only keypoints should be used.
View in stereo
Yes = Displays the cross section view window in stereo mode.
No = Displays the cross section view window in standard mode.
Drape line to VrPoints
Yes = Line is draped to VrPoints
No = Line is not draped. It is assumed that the line has already been draped or follows the surface.
Workspaces to consider when draping
Current = Only uses points in current workspace.
All open = Uses points from all open workspaces.
Initialize line before draping
Yes = All points except the line end points are removed before draping the line.
No = Existing points on line will remain
Drape offset distance (ground)
Defines in ground units the distance from the left and right of the cross section line to search for points to use to define the cross section.
Drape minimum slope change
Defines the minimum slope change for break detection when draping to VrPoints. Surface slopes range from 0.0 to 1.0. 0.0 is a flat line and 0.5 is a 45 degree slope.
Drape break detection spacing (ground)
Defines in ground units the search spacing when detecting breaks in surface.
Drape point spacing (ground)
Sets in ground units the point spacing when draping to VrPoints. 0=No set point spacing - Use slope change and insert points at surface breaks.
Show cross section as
Default viewing mode of cross section line.
Lines = Only shows cross section line.
Points = Only shows points along section line
Line and points = Shows points and cross section line
The cross section viewer window is used to display the cross section profile. The viewer has many options to control how the cross section profile is displayed. A companion window is used to control the display of each pass and to allow the cross section lines from each pass to be saved. Passes are used to display multiple versions of the same cross section line draped to different sets of points.
Below is the main cross section view with a cross section line and points displayed and the companion pass control dialog. Two passes have been taken and the lines are ready to be saved.
The display settings are altered by pressing the Show Settings button. To configure settings outside the Insert Cross Sections application you may use the Configure Cross Sections (ConCro) application .
