 **Step 3**: Use the r.grow.distance function to create a continuous raster map in which each pixel is assigned the distance from the closest route. Use the routes layer in raster format (Step 6) as the input.  ​ **Step 3**: Use the r.grow.distance function to create a continuous raster map in which each pixel is assigned the distance from the closest route.
