Split a river corridor into segments — delineate

Segments are defined as corridor subregions separated by river-crossing transversal lines that form continuous strokes in the network.

Usage

delineate_segments(corridor, network, river, angle_threshold = 100)

Arguments

corridor: The river corridor as a simple feature geometry of class sfc_POLYGON
network: The spatial network of class sfnetwork to be used for the segmentation
river: The river centerline as a simple feature geometry of class sf::sf or sf::sfc
angle_threshold: Only consider angles above this threshold (in degrees) to form continuous strokes in the network. The value can range between 0 and 180, with the default set to 100. See rcoins::stroke() for more details.

Value

Segment polygons as a simple feature geometry of class sf::sfc_POLYGON

Examples

if (FALSE) { # interactive()
bucharest_osm <- get_osm_example_data()
corridor <- bucharest_dambovita$corridor
network <- rbind(bucharest_osm$streets, bucharest_osm$railways) |>
  as_network()
river <- bucharest_osm$river_centerline
delineate_segments(corridor, network, river)
}
