Lattice database / Import fence contents
Not Lite, Not UAV, Not Spatix
Import fence contents command provides an option for creating a triangulated surface model from lattice database points inside a fence. The fence may overlap several individual lattice files. A triangulated surface model enables the addition of new elevation data, such as random points or breaklines. However, changes to the surface model can not be saved into the lattice database files.
A triangulated surface model requires a lot more memory than a lattice model file, if all the lattice points are used in the triangulation. Therefore, it might be necessary to leave out some of the lattice points. TerraModeler is capable of leaving out less relevant points and still building a triangulated network within a given tolerance of the original grid points.
To triangulate lattice database points:
1. Place a rectangular fence.
2. Select Import fence contents command from the Utility / Lattice database pulldown menu.
This opens the Import Lattice File dialog:
3. Define settings and click OK.
This opens the Surface Settings dialog. Continue as described for the File / New surface command.
The software processes all lattice files inside the fence and creates a triangulated surface model from the points.
Setting |
Effect |
---|---|
Surface |
Surface to be created from the lattice file. Always New surface. |
Thin model |
If on, the software leaves out less relevant points from the lattice file in order to reduce the file size of the surface model file. |
Tolerance |
Elevation tolerance for creating the model from the original lattice file. The surface model may differ in elevation up to the given value from the original. This is only active if Thin model is switched on. |
