BackgroundEngland, Scotland & Wales recognise that forest roads are a key part of forest infrastructure
England needs usage & condition survey of forest accesses to justify more investment
Wales wants a database of all civil engineering assets
Scotland wants to improve their road planning
Forestry Civil Engineering begins development of a stand-alone GIS tool to enable improved recording of road data including usage, construction and maintenance details.
Forestry Civil Engineering trials GPR, video and IRI in conjunction with Roadscanners.

Process
Part 1
Define the usage of each segment of road in terms of low, medium or high for timber traffic, light vehicles, cyclists, horses, walkers and other
Decide on the optimum surfacing solution for each usage combination
Record the actual condition against the optimum
Estimate the cost of moving to the optimum solution
Part 2
Assess the strength of roads for harvesting purposes
Record the condition of other features which include the sensitivity of the area to water (this determines the attention paid to side drains and culverts), the condition of side drains, surface potholes, road shape and vegetation
Transfer all data to ArcGIS

Process – Part 2
• Objective 1: Analyse the existing road structure using Ground Penetrating Radar (GPR), GPS, video, roughness and Falling Weight Deflectometer (FWD) data
• Objective 2: Display the results in GIS in a format readily understood by all users.

Data Storage
• Too much data for storage on Forest District servers
• Dedicated area provided on a Silvan House server
• Road Doctor Viewer installed on the server• Remote access to be given to Civil Engineers
• Next version of “Forester” GIS will be able to display all outputs shown in the following table:
