roads (version 1.2.0)

roads-package: roads: Road Network Projection

Description

Iterative least cost path and minimum spanning tree methods for projecting forest road networks. The methods connect a set of target points to an existing road network using igraph https://igraph.org to identify least cost routes. The cost of constructing a road segment between adjacent pixels is determined by a user supplied `weightRaster` and a `weightFunction`; options include the average of adjacent `weightRaster` values, and a function of the elevation differences between adjacent cells that penalizes steep grades. These road network projection methods are intended for integration into R workflows and modelling frameworks used for forecasting forest change, and can be applied over multiple timesteps without rebuilding a graph at each timestep.
