### Basic Parameters

**Neighborhood Dist**

The distance in the XY plane that shouldn't contain another pole.

**Slice Thickness**

The thickness of the slices in which the algorithm will detect the pole.

**Height Min**

The minimum height of the detected pole.

**Diameter Min**

The minimum diameter of the detected pole.

**Diameter Max**

The maximum diameter of the detected pole.

**Remove Trees/ Signs**

The option to exclude or include trees and signs in the pole detection.

**Fence Slices Min**

The minimum percentage of slices that have to be identified as a fence to classify the pole as being part of a fence.

**Ground Offset**

Maximum distance from the bottom of the pole to the ground surface.

**Pole Points Min**

The minimum number of point cloud points a detected pole has to contain.

### Advanced Parameters

**Cell size**

The size of the cell used for the scanning grid.

**Cell size overlap**

The overlap of cells on the scanning grid.

**Cell points min**

The minimum number of points required in a scanning grid cell.

**Histogram Cell Size**

The size of a cell from the histogram grid.

**Slice Overlap**

Percentage of Z slices' height to overlap each other, allowing consecutive slices to be similar.

**Pole Gap Max**

The maximum vertical gap in the point cloud for a pole.

**Height Max**

The maximum height of a pole.

**Proximity Distance**

The maximum distance in the XY plane between the cluster and the individual point to be added to the cluster.

**Ground Margin**

If the terrain is not exactly flat next to the pole (high grass or other noise next to pole) the ground margin defines “thickness of the ground”.

**Remove poles not on the ground**

Remove poles that are distant from the ground.

**Circle Ration Min**

The ration of two perpendicular diameters of a circle. A perfect circle has ratio 1.

**Mask Cell Size**

Cell size of masking grid on a slice.

**Diam Exceeded Max**

The maximum percentage of slices for which the candidate pole can exceed the maximum diameter.

**Mask Matching Min**

Minimum average “consecutive mask comparison” percentage.

**Tree Stalk Height Min**

Minimum height for the stalk of a tree.

**Tree Slice Z Size**

Z-slice to be used to identify the Crown of a tree.

**Tree Slice Circle Ratio Min**

The ration between two perpendicular diameters of a sliced tree. A perfect circle has ratio 1.

**Sign Thickness Max**

Maximum thickness for a sign, measured in depth.

**Sign Diam Min**

Minimum average diameter for a sign.

**Sign Relative Z size Max**

Relation to the total pole height.

**Get point cloud selection mergec**

Get a selection file with the detected features.

**Get point cloud selection**

Get a selection file with the points belonging to the detected feature.

## Examples

- Small pole close to the big one might not be found as it will not show a density peak at the location of a smaller pole. Parameter to change to have higher probability to find the small pole as well:
**Histogram Cell Size**.
