corridor_edge: Draw a corridor edge on the spatial network.

In rcrisp: Automate the Delineation of Urban River Spaces

Draw a corridor edge on the spatial network.

Description

The corridor edge is drawn on the network as a shortest-path link between a start- and an end-point. The weights in the shortest-path problem are set to account for a) network edge lengths, b) distance from an initial target edge geometry, and c) an excluded area where corridor edges are aimed not to go through. The procedure is iterative, with the excluded area only being accounted for in the first iteration. The identified corridor edge is used as target edge in the following iteration, with the goal of prioritising the "straightening" of the edge (some overlap with the excluded area is allowed).

Usage

corridor_edge(
  network,
  end_points,
  target_edge,
  exclude_area = NULL,
  max_iterations = 10
)

Arguments

network	The spatial network used for the delineation
end_points	Target start- and end-point
target_edge	Target edge geometry to follow in the delineation
exclude_area	Region that we aim to exclude from the delineation
max_iterations	Maximum number of iterations employed to refine the corridor edges

Value

A simple feature geometry representing the edge (i.e. a linestring)
