Height metrics

Algorithm ID: hedgetools:heightmetrics

This tool takes a polygon vector layer representing hedges and a Digital Height Model (DHM) and computes descriptive height statistics.

Remark

The height statistics reflect the DHM values, which only capture the vegetation canopy and provide no information about the internal structure of the hedge.

Parameters

Label	Name	Type	Description
Input polygon layer	INPUT	[vector: polygon]	Polygon vector layer representing the hedges.
Input height raster (DHM)	RASTER	[raster]	Digital Height Model representing the height of objects above ground.
Height band	BAND	[raster band] Default: 1	Height band of the DHM raster in case of multiband.
Output height layer	OUTPUT	[vector: polygon] Default: [Create temporary layer]	Output polygon vector layer.

Outputs

Label	Name	Type	Description
Output height layer	OUTPUT	[vector: polygon]	Polygon vector layer with five new fields: height_mean (mean height), height_median (median height), height_min (minimum height), height_max (maximum height), and height_std (standard deviation of height).
