Valley Ridge Peak
Virtual Surveyor includes a tool which uses TIN surface to change the elevation terrain. This tool is helpful to clean a noisy part of your drone data like a water surface. You can also use Modify Terrain to incorporate existing 3D data into your drone survey.
Modify Terrain is available in the SELECTION - TOOLS tab when at least one surface item is selected.
Quick guide
- Select a surface item.
- Go to the SELECTION - TOOLS tab and click on Modify Terrain.
- A Terrain Modifier is created and the elevation terrain is adjusted to the surface.
Usage
- You can use Modify Terrain to flat noisy water surface.
- Using Modify Terrain allows you to model a complex surface (e.g., with breaklines) underneath the large unwanted objects in your drone survey.
- Use Modify terrain to add design surface from CAD plan to your project.
Tips and Tricks
- It is possible to go back to the original elevation after modifying the terrain. When you click Modify Terrain, Virtual Surveyor creates a terrain modifier item. If you disable that item in the project view, the elevation terrain gets back to its initial state.
- Terrain modifier are highlighted in the viewport when selected in the project view.
- Modify Terrain can be done with multiple surfaces at once. Select all the surfaces and click Modify Terrain. One Terrain Modifier is created for each surface.
- You can also use Replace Terrain and Remove Object to flat a small area of your drone survey.
