This document summarizes a review meeting for Project SLOPE Work Package 2 on forest information collection and analysis. The task involved defining a methodology to characterize forest status using remote sensing data from multiple sensors. Partners completed the task of determining useful vegetation indices from satellite, UAV, and laser scanning data to estimate biological parameters. The group analyzed parameters with increasing detail and resolved issues related to selecting case study sites with comparable satellite and UAV data. They concluded that the work established an integrated system to monitor forests and provided detailed tree-level information for management using different data sources.

Issues, delays and actions
• Case study chosen, with post inspection, revealed too young/thin
trees
• The alternative (Gortahile forest) was not present in Sat data
(geographical mismatch)
•Action Taken: Acquisition of EO images over the Trentino area visited
with UAVs in order to have a comparable dataset
• Possible issue (resolved): lack (at least for now) of a specific band
(RE) which could be useful for tree inspection in UAVs camera

WP2 Problems experienced & Solutions
Weather can be a problem such as high winds / snow
Access permits are required / permission was granted by
ENAC & the Forest Wardens.
GPS quality is poor the accuracy was 250mm but suffecient
for forestry new developmemts of an RTK UAV does away
with the need for GCP’s
Access to the mountain forest was restricted so a small
clearing was located to enable launch of the UAV.

Advantages of using Multispectral Camera
Growth and yield of the forestry crop is the result of its interaction with
environmental factors, soil conditions and availability of water and nutrients in the
soil.
With the availability of crop-health detecting sensors,
it its now possible to obtain indicator kinetics such as NDVI, biomass, chlorophyll
rate, leaf area index, water stress, flowering ,on a much smaller scale than
before.
Multispectral imagery can determine the health, Species, of
trees
The multispectral imagery can help determine haul routes
by the reflection from different soil types.
The imagery can be used to determine growth rates over
several seasons and help determine where thinning is
required.
Coastway have received a lot of interest from Forestry
companies in the UK & Ireland regarding forestry
management.

Spatial information is essential in order to know how the forest parameters are spatially
distributed in the forest stand. Therefore, the combination of forest parameters and
remote sensing must be used to study how the dendrometric parameters are distributed.
Typically, the spatial analysis is based on the following steps:
1. Location of the forest area (Area of analysis).
2. Pre-processing of the image
3. Zoning for analysis.
4. Delineation of the forest canopy (Forest productive area).
5. Tree detection (if applicable).
6. Forest stratification based on tree characteristics (if applicable).
7. Inventory Plan (Samples plot location).
8. Generalization based on field data (parameters distribution and final
stratification).

Known limitations
1.- Tree level inference
•High resolution (higher than 30 cm) required for tree detection (e.g. UAV)
•Hidden trees under forest canopy can be height (63%) in mixed stand.
Improvement expected in even-age plantations
•Field tree locations (GPS) do not match correctly tree crown detected by UAV
(Ideally to be used in area with good GPS signal and use corrections when
required)
•Limited species detection (Improvement expected to be used in pure stands)
•Relative good correlation between Volume and Crown/Height (around 70%)
2.- Area based inference
•Not possible to work with individual trees
•Limited information about the distribution of the timber within the forest.

•The use of UAV image (0.2cm) or medium resolution EO (0.5m) can improve
significantly the field inventory planning.
•The combination of TLS and UAV image can improve significantly the estimation
and location of the timber in the forest.
•The analysis of allometric relationships at tree level has result successful using
UAV stereo analysis and very limited using EO data .
•The estimation of the timber in the forest need to take into the trees hidden trees

Spatial information is essential in order to know how the forest parameters are spatially
distributed in the forest stand. Therefore, the combination of forest parameters and
remote sensing must be used to study how the dendrometric parameters are distributed.
Typically, the spatial analysis is based on the following steps:
1. Location of the forest area (Area of analysis).
2. Pre-processing of the image
3. Zoning for analysis.
4. Delineation of the forest canopy (Forest productive area).
5. Tree detection (if applicable).
6. Forest stratification based on tree characteristics (if applicable).
7. Inventory Plan (Samples plot location).
8. Generalization based on field data (parameters distribution and final
stratification).

Known limitations
1.- Tree level inference
•High resolution (lower than 30 cm) required for tree detection (e.g. UAV)
•Hidden trees under forest canopy can be height (63%) in mixed stand. Ideally to
be used in even-age plantations
•Field tree locations (GPS) do not match correctly tree crown detected by UAV
(Ideally to be used in area with good GPS signal and use corrections when
required)
•Limited species detection (ideally to be used in pure stands)
•Relative good correlation between Volume and Crown/Height (around 70%)
2.- Area based inference
•Not possible to work with individual trees
•Limited information about the distribution of the timber within the forest.

•The use of TLS in forest inventory improves significantly the estimation
of tree volume
•The use of UAV image (0.2cm) or medium resolution EO (0.5m) can improve
significantly the field inventory planning.
•The combination of TLS and UAV image can improve significantly the estimation
and location of the timber in the forest.
•The analysis of allometric relationships at tree level has result successful using
UAV stereo analysis and very limited using EO data .
•The estimation of the timber in the forest need to take into the trees hidden trees

1.Task objectives
 LOGISTIC OPTIMIZATION MODEL:
 The goal is to determine an optimal forest logistic
network to respond future demands.
 The approach would determine:
 Allocation of each buffer to the customer considering lowest
supply costs
 Which storage yards to open and how much timber will flow
via these yards during damage events, i.e. when too much
timber is produced within a certain period

2.a. Main logistic elements
Central storage yards (S) are intended to
balance supply and demand.
- Enough stock for continuously supply
during period when no harvesting is
possible.
- Limited capacity.
Forest roads respond to limited requirements of forest
processes.
Features defined by characteristics of traffic:
- Low traffic.
- Traffic in one direction.
- Long and heavy trucks.
Buffers (B) are forest resources represented
as roadside stocks.
Typical amounts of timber at the buffer
are relatively small and accounts for
only a few truck loads per site.
Processing sites are those areas were logs are handled
to obtain the final ptoduct demanded by customers.

 Al major tree species in Austria (Norway
spruce, Fir, Larch, Scots pine, Beech, Oak,
etc.).
 Elevation: 400 m - 900 m.
 Timber volume: 287,000 m3 (320 m3/ha).
 Annual increment: 7.8 m3/ha.
 Average slope: 31%.
 50% below 30%
 46% between 30 and 60%
 4% over 60% (only harvested by tower

technologies.
2.d. Implementation and trials
 Test with real data:
 Storage yard “S3” will be opened.
 All other timber transports are carried out
directly to the customers.
 Objective value (total supply costs): 72,769
€
 Supplied timber: 25.80 € per m³
 Other “fictitious” tests:
 C2 demand implies less costs (more profitable). It
could derive in different prices policies decisions
depending on customer.
 Customers’ demand distribution not influence
storage area to open (S3).
 Influence of different customers. Different
demand were tested: 3 scenarios
concentrating demand on each customer.
 If S3 forced to close.
 Effect of cost reduction in parts of the process.
I.e. reducing harvesting costs in 30%.
 Costs using alternative storage areas not almost
affected. Appropriate contingency plan using S2.

 Developed a logistic optimization model for a regional wood supply network
based on an objective function, which minimizes transportation costs.
 Model integrated with the whole SLOPE model to support the decision for
the optimal supply network.
 Model developed based on:
Kanzian, C., Holzleitner, F., Stampfer, K. & Ashton, S. 2009
“Regional Energy Wood Logistics – Optimizing Local Fuel Supply”.
 Logistic model implemented using XPRESS software.
 Test done using real data from State Forests in Austria.
 Possible improvements:
 Include in the model other relevant aspects for forestry companies (restrictions in
seasons with bad weather conditions…).
 Completing this task with a tool for visualization of storage areas and the
determination of the capacity.
