Swiss Forest Access Roads Inventory for Timber Transport

Forest Access Roads 2013 is a nationwide geospatial dataset of truck-accessible forest roads in Switzerland, updated through a 2013-2014 survey. The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) manages the data, which was collected by interviewing staff from approximately 800 local forest services. Information on road trafficability for specific truck categories is attached to geometries from the swissTLM3D base map.

Use Cases

• Model timber transport logistics using the road trafficability attributes for specific truck categories.
• Analyze national forest infrastructure coverage by integrating the road geometries with forest inventory data.
• Assess regional accessibility for forestry operations based on the surveyed road network connected to local forest services.

Strengths

• Nationwide coverage of Switzerland's forest road network.
• Data collection involved approximately 800 local forest service units.
• Includes specific attributes for truck trafficability attached to detailed swissTLM3D geometries.

Limitations

• Spatial accuracy may be insufficient for applications like navigation systems without further validation.
• Data is based on a survey from 2013-2014 and may not reflect recent changes.
• Non-commercial use requires purchase of a separate TLM license from swisstopo.
