Road Slope Calculator

(14) votes 

This algorithm is used to calculate the longitudinal slope of forest paths and roads, based on a 2D line vector layer and a DEM (Digital Elevation Model). It should not be used on national road systems, such as highways, motorways, national and regional roads, which have engineering works designed to smooth the slope (bridges, excavations, landfills, etc.), unless the user has access to a high precision Digital Surface Model (DSM). Not to be used with line vector layers in geographic coordinates.

To run this plugin, go to Processing menu, open Toolbox window, and look for Road Slope -> Road slope calculator. For more (important) information, visit
