Analyse LoS

Analyse line-of-sight layer. Calculate the attributes according to type of line-of-sight (see Outputs).

Parameters

Label Name Type Description
LoS layer LoSLayer [vector: line] LoS layer to analyse.
Use curvature corrections? CurvatureCorrections [boolean]

Default: True
Should the curvature and refraction corrections be used?
Refraction coefficient value RefractionCoefficient [number]

Default:
0.13
Value of refraction coefficient.
Output layer OutputLayer [vector: line] Output layer containing LoS with new attributes.

Outputs
