The Section Profiles tool is a road analyzing tool inspired by traditional road surveying techniques. This button will drop cross section profiles along an axis. Those profiles can be displayed in the profile view and saved as an image


The Section Profiles tool only works on the selected polyline or profile and appears in the TOOLS tab for polyline and the TOOLS tab for profile.  




Quick Usage Guide

  1. Select the polyline or the profile which is drawn over the axis of the road.
  2. Go to the TOOLS tab. 
  3. Set the appropriate Along and Across values in the boxes available in the Create group.
  4. Click on Section Profiles button in the same group.
  5. Section profiles are drawn along the axis and grouped in a new layer in the project view. 


Tool Settings

Set the appropriate Along and Across values before launching the section profiles creation process.


Along value represents the spacing between two successive section profiles along the axis. Determine this value on the basis of your survey requirements and the road topography. In addition to section profiles determined by the Along value, other section profiles will also be drawn at the vertices of the center line. 


Across value represents the length of the section profile. In other terms it's the width of your survey. To easily determine this value, approximately measure the distance between the center line and the boundary of the area to be surveyed (end of pavement, drain ditch...). Double this distance and use it as Across value.



Usage

  • The Section Profiles tool is a part of the Virtual Surveyor toolbox for road surveying. You can use it to generate a set of cross sections at regular intervals along a the center line of a road. Then analyze the cross section profiles in the profile view and copy the profile plots to illustrate the road analysis report. 
  • You can also use the Section Profiles tool to analyze haul road safety over time. In the example below, the second survey (black profile - March 2019) was conducted after a haul road maintenance. Comparing to the pervious survey (blue profile - January 2019), you can see that the safety berms have been reshaped on the sides of the track.
