Road Surface Module FAQ

Create TIN

1. [Warning] "Too few key points, cannot create a TIN struct"
   • Warning Reason: The number of key points is too few, resulting in the failure to create a TIN.
   • Solution: Ensure that the selected layer or area has at least 3 key points.
2. [Warning] "No object in selected layer"
   • Warning Reason: There are no objects in the selected vector layer, leading to the failure to read key points.
   • Solution: Ensure that there is at least one object in the selected layer or area.

Vehicle Passability Analysis

1. [Warning] "Failed to load simulation file"
   • Warning Reason: The simulation file is corrupted.
   • Solution: Recreate a new passability analysis to regenerate the simulation file.

Based on Point Cloud

1. [Warning] "A layer with the same name already exists"
   • Warning Reason: The raster image has the same name, causing the addition to the project to fail.
   • Solution: Change the name or remove the existing raster with the same name.
2. [Error] "Unable to open raster: ..."
   • Warning Reason: The raster image is corrupted, causing the addition to the project to fail.
   • Solution: Regenerate the raster image.

Based on TIN

1. [Warning] "A layer with the same name already exists"
   • Warning Reason: The raster image has the same name, causing the addition to the project to fail.
   • Solution: Change the name or remove the existing raster with the same name.
2. [Warning] "No 'Road Pavement' exists"
   • Warning Reason: There is no valid Road Pavement model scene available.
   • Solution: Use road surface grid points and the create TIN function in advance to create the road surface model.
3. [Error] "Unable to open raster: ..."
   • Warning Reason: The raster image is corrupted, causing the addition to the project to fail.
   • Solution: Regenerate the raster image.
