Thank you.
Do you use the software just to try out and adjust different layouts or does the software actively propose routes based on optimizations done using the input data (DEM, WOF,...)?
What products (Debaser mentioned MX[road?]) are available and widely used?
I was wondering how civil engineers plan roads embedded in rugged terrain (e.g. over a mountain). How do you find an optimal route (length, allowable gradient, minimal amount of earth moved,...) Is there any software for this or is it done 'by hand'?
