canyon

Geometric functions, polygon operators canyon

syntax

• canyon(point, z, sequence_rel, segm_start, segm_end, arcs, arc_height, minHeight, maxCanyonDist)

definition

canyon computes street-canyon indicators for a set of (road) points: for each point the right and left canyon contribution (sub items rrc and lrc) given the surrounding line segments (e.g. building facades) with their heights. Segments lower than minHeight or further away than maxCanyonDist do not contribute.

This operator is exercised in the GeoDMS-Test operator test (Sequence/UnTiled/canyon), which can serve as a working example configuration.

This page is an initial stub generated from the operator test; please extend with the exact result definition.
