I want to extract following road terrain data from DEM but I'm not sure if its possible. Can i extract these attributes using LIDAR if not DEM ?
These are the data fields I need:
Horizontal curve location, Horizontal curve length, Grade in direction of travel, Roadway elevation, Roadway elevation, Vertical curve location, Vertical curve length, Available sight distance, Road cross slope, Shoulder cross slope
Any information would be helpful.
