Width

Algorithm ID: hedgetools:width

This tool takes a polygon vector layer representing hedges and a line vector layer representing their median axis, and computes the width of each polygon.

Parameters

Label	Name	Type	Description
Input polygon layer	INPUT_POLYGON	[vector: polygon]	Polygon vector layer representing the hedges.
Input arc layer	INPUT_ARC	[vector: line]	Line vector layer representing the hedge median axis.
Width method	METHOD	[enumeration]	Method used to compute width: 0: Accurate – Computes perpendicular transects along the median axis and measures their length. 1: Approximate – Computes the distance from the median axis to the closest polygon boundary and multiplies it by 2.
Sampling distance (meters)	DISTANCE	[numeric: integer] Default: 10	Interval along the median axis used for width sampling.
Percentile for outlier removal	PERCENTILE	[numeric: integer] Optional	Removes extreme width values using the IQR method with the specified percentile before computing summary statistics.
Output width layer	OUTPUT	[vector: polygon] Default: [Create temporary layer]	Output polygon vector layer.

Outputs

Label	Name	Type	Description
Output width layer	OUTPUT	[vector: polygon]	Polygon vector layer with five new fields per selected method: width_method_mean (mean width), width_method_med (median width), width_method_min (minimum width), width_method_max (maximum width), and width_method_std (standard deviation of width). Where method is either acc or approx.
