Simulating cable corridors based on terrestrial LiDAR data

Area of Science:

• Forestry Science
• Geographic Information Systems
• Sustainable Resource Management

Background:

• Traditional timber extraction on steep terrain faces challenges with inaccurate contour maps for cable corridor planning.
• Infeasible support points and reduced confidence in generated layouts are common issues with current methods.

Purpose of the Study:

• To introduce a novel digital twin-based approach for optimizing cable corridor layouts in steep terrain timber extraction.
• To enhance the accuracy and feasibility of cable corridor planning, reducing operational costs and promoting sustainability.

Main Methods:

• Utilizing high-resolution tree maps and digital terrain models to create realistic forest digital twins.
• Applying established forestry methods to compute feasible cable corridors, considering rope deflection, tree anchors, and intermediate supports.

Main Results:

• The digital twin approach generates realistic representations of potential cable corridors.
• Feasible cable corridor trajectories are identified, forming a basis for optimized overall layouts.

Conclusions:

• The proposed method improves the accuracy of cable corridor planning for steep terrain timber extraction.
• This approach supports cost reduction and promotes sustainable forestry practices, with future work focusing on multi-criteria optimization and user-friendly integration.
