Morph raw map data into a road network

morph_road_network.Rd

morph_road_network() converts map data from the RoboCup Rescue Simulation into a road network.

Usage

morph_road_network(map_data)

Arguments

map_data

rrs_map data, the GML map data loaded by the read_rrs_map().

Value

A list containing the network components:

  • nodes: A sf object of nodes with point geometries.

  • edges: A sf object of edges with linestring geometries.

Details

This road network consists of nodes and edges. Nodes are defined as the centroids of all areas and the center points the boundaries between areas. Edges connect nodes between an agent can travel.

Examples

gml <- system.file("extdata", "map-test.gml", package = "rrstools")
map_data <- read_rrs_map(gml)
network <- morph_road_network(map_data)
