Plan and cross section view
The plan view of the road appears for a Trimble or LandXML road only when you are surveying from the map or when you use the menu to select the road but then choose the graphical selection method for stakeout.
The plan view of the road always appears for a GENIO road.
To switch between the plan view and the cross section view, tap or , or press the Tab key.
To measure your position relative to the road, tap Start.
To measure your position relative to the string, tap a string and then tap Start.
To stake out a position, tap a station on a string and then tap Start.
Alternatively use the softkeys to select a string and/or station to stake. To add features for stakeout, such as a construction offset or a cross slope, tap and hold in the plan view and select the appropriate item.
To clear the current selection in the plan view, tap the selected item again or tap in a clear space.
The plan view shows:
- Horizontal alignment/master string as a red line
- Other strings as black lines
- Construction offsets as green lines
- Skew offsets as dashed black lines
Before stakeout the plan view shows:
- Construction offsets as green lines
- Skew offsets as dashed black lines
Alongside the plan view, before stakeout the software shows:
- Station (when staking a station on a string)
-
String name (when staking a station on a string or measuring your position relative to a string)
For a Trimble road, the software uses the string name from the template definition. When the offset is 0.000 m, the string name defaults to CL.
- Design elevation of the selected position (shown in red if edited)
- Construction offsets
- When staking a station on a string, the software also shows:
- Type
- Offset
- Elevation (shown in red if edited)
- When staking a side slope, the software also shows the:
- Design side slope values
- Cut ditch width (Trimble roads only)
- When staking a skew offset, the software also shows the:
- Skew offset
- Deflection angle/azimuth
During stakeout the plan view shows a dashed green line drawn from the current position to the:
- horizontal alignment/master string when measuring your position relative to the road and you are within 30 m of the alignment/string
- selected string when measuring your position relative to a string and you are within 5 m of the string
Alongside the plan view, during stakeout the software shows:
- Elevation of your current position (shown in blue)
- When staking a side slope, the software also shows:
- Side slope value defined by your current position (shown in blue)
- Design side slope value (shown in red if edited)
- Off road appears if your current position is before the start of the road or beyond the end of the road.
-
Undefined appears when consecutive horizontal alignment elements are non tangential and your current position is beyond the end tangent point of the incoming element but before the start tangent point of the next element and you are on the outside of the road. See position 1 in the diagram below.
-
When consecutive horizontal alignment elements are non tangential and your current position is before the end tangent point of the incoming element but after the start tangent point of the next element, and your position is on the inside of the road (see position 2 in the diagram below), the station, offset and vertical distance values are reported using the closest horizontal element to your position to determine which portion of the road to use.
The cross section that appears is orientated in the direction of increasing station. Your current position and the target are shown. If the target has construction offsets specified, the smaller single circle indicates the selected position and the double circle indicates the selected position adjusted for the specified construction offset(s). The construction offset(s) appear as green lines.
When you view the cross section, the appropriate cut or fill side slope appears for the side of the road that you are currently on.
If you have set the Design cut/fill field to Perpendicular in the Stakeout options screen, the perpendicular cut/fill position is drawn on the design in the cross section view only when measuring positions relative to the road. Because the cross section view is not drawn to scale, the perpendicular position may appear slightly incorrect (ie. not exactly perpendicular).
Tap and hold in the cross section view to define a cross slope or subgrade.
The base of the plan view or cross section view reports your current position relative to the item being staked:
- To select the delta display, tap the arrow to the left of the navigation deltas.
- Tap Options for further delta display options.
- If you are using a conventional instrument, the road values only appear after you take a distance measurement.
- If the road consists of only a horizontal and vertical alignment the V.Dist value reports the vertical distance to the vertical alignment.
- If your position is in a gap, the V. Dist value is null. Gaps are shown as a dashed line in the cross section view. To see how to create a gap in a template, see To add templates.
When using a GNSS receiver with a built-in tilt sensor, you can:
- Tap eBubble to display an electronic bubble
- Configure the survey style to prompt a warning when the pole is outside a specified Tilt tolerance
- To configure quality control, precision, and tilt settings, tap Options.
