Enhancements

Stake out Trimble roads or LandXML string roads without leaving the map

When staking a Trimble road or LandXML string road from the map the navigation screen now displays the map. This offers a number of advantages including:

  • Greater flexibility and improved workflow.

    For example, when measuring your position relative to the road, you can tap a station on a string to stake that position. After the point is stored you can select another station on a string, measure your position relative to a string by tapping the string or, tap in empty map space to continue measuring your position relative to the road. Previous versions of the software meant you had to leave the navigation screen if you needed to change the stakeout method on the fly.

  • Consistency with the other map views.
  • Map zoom tools are now available when staking the road, enabling you to view the road in the way that suits you best. Zoom tools are also available in the cross section view.
  • You can view the road in 3D as you navigate toward the target. This is particularly useful when both horizontal and vertical construction offsets are applied.

LandXML string road enhancements

  • Station interval: You can now edit the station interval for LandXML string roads. Previously this was hard wired to 20.000m/65.617ft. To edit the station interval, select the road in the map and tap Edit and then tap Options.
  • Available stations: You can now control which stations are available for stakeout. To do this, select the road in the map and tap Stakeout. In the screen where you enter the Antenna height or Target height value, tap Options and then select one of the following options:
    • Computed sections to see the stations defined by the station interval.
    • Horizontal curve to see the key stations defined by the horizontal alignment.
    • Vertical curve to see the key stations defined by the vertical alignment.
    • Design sections to see the stations defined by the positions in the file.
  • Arcs in substrings: The Roads software now supports arcs in substrings in LandXML string roads.

Orbiting the road in 3D drive

You can now orbit the road when reviewing the road using the automated 3D drive-through feature. To do this, tap to pause the drive through and then tap the screen and swipe in the direction to orbit.

Resolved issues

  • Additional strings in LandXML string roads: We have fixed the following issues where:
    • The additional string was incorrectly computed when the string was defined by Offset and calculated slope and the Derive from and Calculated from strings had the same offset.
    • Some strings in LandXML road files may have appeared and behaved as additional strings, but were not additional strings.
  • Reviewing LandXML string roads: When reviewing a LandXML string road, if you select a position or string on another road, the selection is now highlighted. You can also now use the arrow keys to select another position or string.
  • Stakeout when map is orbited: For a Trimble or LandXML string road, selecting a position to stake is now more reliable when the map is orbited. Previously it could be difficult to select the correct position especially when the map was at an acute angle. For a GENIO road Trimble recommends you select positions when the map is in plan view.
  • Staking a subgrade: When staking a subgrade position with a horizontal construction offset, you can now use the arrows keys to select the next (or previous) station. Previously the position defined by the construction offset moved to the new station but the subgrade position remained at the original station. Selecting a station from the list worked correctly.
  • Horizontal construction offset: The horizontal construction offset is now displayed at stakeout when selecting a station on a string, a station on an additional string, or an additional point. Previously the offset was not displayed when the selected position had no elevation.
  • Transition elements in horizontal alignments: We have fixed an issue where the horizontal alignment for a road was displayed incorrectly when there was an unusually small difference in the start and end radii values for partially developed transitions.
  • GENIO roads: Improved performance when reviewing or staking a GENIO road with a very large number of cross sections. Previously it was slow to select a string or a station on a string.
  • Application errors: We have fixed several issues that caused application errors when using or closing the software. In particular:
    • When you attempt to view the cross sections while staking relative to an additional LandXML string, which is defined as an independent string.

    • When you attempt to edit the elevation for a station on an additional string.

    • When you select a GENIO file that contains TT records in the Stakeout screen.
    • When you open a job containing a LandXML string road where the road includes additional strings, the High residual bytes message no longer appears.
    • When you switch to cross section view when staking out in an area that has no side slopes, but has side slopes defined before and after the area.
