1. Big Data applications
Efforte Business Forum
Erik Willén, Isabelle Bergkvist

2. Objectives
Describe potentials in using, refining and linking existing and new
Big Data sources in forestry applications, and evaluate the identified
sources of data through a SWOT analysis.
Based on these data, create decision-support models for
efficient, sustainable and value-creating forestry and forest operations.
Demonstrate the potential in keeping and refining information
throughout subsequent operations in the forestry process.
Validation and pilot tests of project results in relevant
environment (hosted by partner companies).

4. Demonstrated decision support models
 Trafficability maps
 Operational logging trafficability mapping
 Logging trail visualizations and port-harvest quality
control
 Models for operational planning of forest operations
 Yield and wood property forecasting
 Models to improve efficiency in silviculture operations

17. Models to improve efficiency
in silviculture operations
Plant order tool
 Based on harvester data
 Actual growth conditions
 Root rot frequency
 Site index

19. Conclusions
 Operational use of trafficability maps and tools to extract main extraction
routes
 Digital elevation model spatial resolution critical
 Important to act pro-actively to secure data collection
 Interesting potential to use Can-Bus data to for trafficability mapping – other
options also availible (drones, machine-mounted equipment, ..)
 Big data applications opens a wide range of possibilites for research and
applications – standardisation crucial!
 Previous research now possible to implement with Big Data Streams
 Forest machine data key for many applications – start collect standardised
data!
