Walls
Not Lite
Wall routine classifies points on wall-like surfaces in mobile data sets. The routine requires that normal vectors for the points in the source class(es) are available. Normal vectors can be stored as attributes for points in TerraScan FastBinary files. They must be computed by using the Compute normal vectors command.
The routine classifies points on planar surfaces that are nearly vertical (within 10 degree) and larger than a given minimum area. It classifies the points on the surface and also smaller details up to a given distance from the main surface.

Opens the Select classes dialog which contains the list of active classes in TerraScan. You can select multiple source classes from the list that are then used in the From class field. |

Target class. |
Minimum area |
Minimum size of a wall surface. Given in squared CAD file units. |
Tolerance |
Offset from the main planar wall surface up to which points are included in the classification. Given in CAD file units. |
Inside fence only |
If on, points inside a fence or selected polygon(s) are classified. |
