roads: Road Network Projection

Project road network development based on an existing road network, target locations to be connected by roads and a cost surface. Road projection methods include minimum spanning tree with least cost path (Kruskal's algorithm (1956) <doi:10.2307/2033241>), least cost path (Dijkstra's algorithm (1959) <doi:10.1007/BF01386390>) or snapping. These road network projection methods are ideal for use with land cover change projection models.
