flatten_network: Flatten a network by adding points at apparent intersections.

In rcrisp: Automate the Delineation of Urban River Spaces

Flatten a network by adding points at apparent intersections.

Description

All crossing edges are identified, and the points of intersections are injected within the edge geometries. Note that the injected points are not converted to network nodes (this can be achieved via sfnetworks' sfnetworks::to_spatial_subdivision(), which is part of the tasks that are included in clean_network().

Usage

flatten_network(network)

Arguments

network

A network object

Details

The functionality is similar to sfnetworks' sfnetworks::st_network_blend(), but in that case an external point is only injected to the closest edge.

Value

A network object with additional points at intersections

Examples

bucharest_osm <- get_osm_example_data()
edges <- dplyr::bind_rows(bucharest_osm$streets,
                          bucharest_osm$railways)
network <- sfnetworks::as_sfnetwork(edges, directed = FALSE)
flatten_network(network)
