WP 4 – Multi-sensor model-based qualitycontrol of mountain forest production
![Page 2: Kick-Off Meeting - WP4](https://reader038.vdocuments.net/reader038/viewer/2022103104/58a30b991a28abea508b6b7f/html5/thumbnails/2.jpg)
Work Package 4: Multi-sensor model-based
quality control of mountain forest production
Some thoughts after the first day of kick-off meeting:
1. Complements for all partners for fascinating presentations, unique know-how and enthusiasm.
2. The forest in mountains is peculiar, and very different than such of flat lands!!!
3. Trees in mountains are (mostly) BIG…4. Big/old tree may be or superior quality, or “fuel wood”5. Trees from mountains might be of really high value6. We do support with our heart “PROPER LOG FOR PROPER USE”7. The quality of wood/log/tree is an issue!!!!!8. But, the quality of wood is not only external dimentions, taper
and diameter…

Work Package 4: Multi-sensor model-based
quality control of mountain forest production
The goals of this WP are:• to develop an automated and real-time grading system for the forest production, in order to improve log/biomass segregation and to help develop a more efficient supply chain of mountain forest products• to design software solutions for continuous update the pre-harvest inventory procedures in the mountain areas • to provide data to refine stand growth and yield models for long-term silvicultural management

Risks and mitigating actions:
To keep focus on practical applications and not pure (fascinating for us) research; 2-monts progress reporting, contributions/comments of SLOPE partners
Properly define real user expectations; contribution of the development of WP1, discussions with stake holders, foresters, users of forest resources
Technologies provided will not be appreciated by “conservative” forest users; demonstrate financial (and other) SLOPE advantages
Difficulties with integration of some sensors with forest machinery; careful planning, collaboration with SLOPE engineers

Task 4.5: cutting process quality indexComments
The average density and mechanical resistance will be a result of the analysis of the chainsaw cutting process.
Estimation of the “CP-branch indicator” will be computed only in the case of delimbing on the processor head. In this case, it will be correlated to the “3D-branch indicator” determined from the 3D stem model of the original standing tree (T4.1).
The information will be forwarded to the server in real-time and will support final grading of logs.
