Big Data applications - EFFORTE Business Forum

  1. 1. Big Data applications Efforte Business Forum Erik Willén, Isabelle Bergkvist
  2. 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).
  3. 3. Outlook on Big Databases - forest planning Detailed digital elevation model Soil maps VHR imagery Mobile laser scanning Weather data and models Lidar based forest estimates Road databases Forest machine data

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