[Qgis-user] Plot roadline using contours / DEM

[Tony Shepherd (FarmMaps NZ)]

Hi All

 

I would like to plot a line (potential road) using a given slope (or grade)
using contour lines.  I imagine picking a start point, entering a grade and
somehow plotting the road line.  I also have a DEM that I could use if that
was possible.  Is there a plugin available to assist with this?  Accuracy
isn't all that important as it's for a potential road in a forestry block,
but Id like a shp file produced that I could then load into my drone to fly
the route before more precise planning took place.

 

Cheers

Tony
