The Section Profiles tool is a road analyzing tool inspired by traditional road surveying techniques. Section Profiles drops cross-section profiles along an axis. The profiles can be displayed in Profile View and saved as an image.
Quick Usage Guide
- Select the polyline or the profile that is drawn over the axis of the road.
- Go to the TOOLS tab.
- Set the appropriate Along and Across values in the boxes available in the Create group.
- Click on Section Profiles in the same group.
- Section profiles are drawn along the axis and grouped in a new layer in the Project View.
Set the appropriate Along and Across values before launching the section profiles creation process.
The 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.
The Across value represents the length of the section profile. In other words, it is the width of your survey. To easily determine this value, measure the distance—using the measurement tools in the ANALYSIS tab—between the center line and the boundary of the area to be surveyed (end of pavement, drain ditch, etc.). Double this distance and use it as the Across value.
Where to Use the Section Profiles Tool
- The Section Profiles tool is a part of the Virtual Surveyor toolbox for road surveying.
- You can also use the Section Profiles tool to analyze haul road safety over time.
- In the example image below, the second survey (black profile - March 2019) was conducted after a haul road maintenance.
- Compared to the pervious survey (blue profile - January 2019), you can see that the safety berms have been reshaped on the sides of the track.
