The methods\nconnect a set of target points to an existing road network\nusing 'igraph' to identify least cost\nroutes. The cost of constructing a road segment between\nadjacent pixels is determined by a user supplied weight raster\nand a weight function; options include the average of adjacent\nweight raster values, and a function of the elevation\ndifferences between adjacent cells that penalizes steep grades.\nThese road network projection methods are intended for\nintegration into R workflows and modelling frameworks used for\nforecasting forest change, and can be applied over multiple\ntime-steps without rebuilding a graph at each time-step.", "License": "Apache License (>= 2)", "Encoding": "UTF-8",
