Road Analysis Module FAQ

Processing Pipeline

1.[Error] No vector lines.

Error Reason: The "Power Line" layer has no vector line data.
Solutions: Place the power line data into the "Power Line" layer.

2.[Error] No from class in point cloud.

Error Reason: The point cloud has no source class.
Solutions: If the source class is set incorrectly, reset the correct source class. If it is set correctly, perform point cloud classification first.

3.[Error] No road regions.

Error Reason: The "Lane Centerline" layer has no vector line data.
Solutions: Place the road line data into the "Lane Centerline" layer.

4.[Error] Empty *imglist path.

Error Reason: No imglist data.
Solutions: Add an imglist file to the project and ensure that the corresponding images exist.

Clearance Analysis

1.[Clearance Analysis] Failed to register scalar field 'ClearanceID'.

Error Reason: Failed to register additional attribute fields. The point cloud may be occupied by another program, or the LiData version is lower than 2.0.
Solutions: Close the occupying program and upgrade the LiData file version.

Hight Limit Analysis

1.[Hight Limit Analysis] No ground points to drape.

Error Reason: The analysis location lacks ground points.
Solution: Ensure that ground points exist in the analysis location and that the ground point category is correctly specified. Increase the absolute value of the Cylinder Bottom parameter to ensure ground points can be captured.

2.[Hight Limit Analysis] Layer '' was deleted.

Error Reason: The power line layer has been deleted.
Solution: Re-analyze and recalculate using Hight Limit Analysis.

3.[Hight Limit Analysis] Config record was deleted.

Error Reason: The relevant configuration for the analysis has been deleted.
Solution: Re-analyze and recalculate using Hight Limit Analysis.

Place Tile Array

1.[Place Tile Array] No trajectory segments.

Error Reason: No trajectory segments.
Solution: Select the trajectory segments on the 3D view trajectory first, then proceed with processing.

Section Analysis

Section Engineering Management

1.[Warning] "Cannot switch active project now"

Error Reason: The section engineering cannot switch the active project while the calculation is in progress and the 2D display window is open.
Solution: Wait for the calculation to finish and close the 2D display window.

Calculation Attribute

1.[Warning] "No valid data"

Error Reason: Measurement section has not been generated.
Solution: Generate the measurement section for the current group.

Export Section

1.[Warning] "Something wrong happens when exporting sections"

Error Reason: Export failed.
Solution: Remake the sections or contact technical support.

2.[Warning] "Export failed"

Error Reason: There is currently no active section project, leading to export failure.
Solution: Right-click on the section directory management number to activate the active project.

3.[Warning] "Import failed"

Error Reason: 1. There is currently no active section project, leading to export failure; 2. The data input path is empty.
Solution: 1. Right-click on the section directory management number to activate the active project; 2. Enter the correct data path.

4.[Warning] "No valid section"

Error Reason: No measurement section for the cross-section.
Solution: Generate the measurement section.

5.[Warning] "Exporting section failed in: ..."

Error Reason: The specified measurement cross-section was not found.
Solution: Rerun the calculation of the measurement section to synchronize the data.
