Op Tracker™ - Mobile Op Tracker™ - Web App
Rayonier Advanced Materials Confidential and Proprietary Information
Business Benefits
▪ Operators utilize liDAR predicted forest inventory metrics and elevation models to better plan their harvest activities.
▪ Improved operator experience and productivity that leverage lidar information products.
▪ Simplified data management as instead chasing operators to download GPX files from various recreational GPS units, Op Tracker™ track data are synced.
▪ Tracking information is now used to provide a first cut of depletion mapping prior to flying photography with focus shifted on QC instead of digitization.
▪ Web app provides staff with up-to-date cut progress to inform planning and silviculture activities and analytics for insight in to business operations.

Project Objectives
▪ This project has four main objectives: – (i) propose a structurally guided sampling design for locating and
collecting FRI calibration plots for model development for the 2018 SPL. [COMPLETE]
– (ii) Coordinate procurement and delivery of field data collection services using the draft Integrated Monitoring Framework (IMF) design specifications,
– (iii) develop an EFI and examine the utility of both Area Based Approach (ABA) and Individual Tree Detection (ITD) approaches using SPL data and
– (iv) assess growth and change using previous acquired 2005 LIDAR data.

Structurally Guided Sampling for Locating Plots
▪ SPL metrics have been calculated over the entire RMF on a 20m x 20m grid (400 m2, corresponding to plot area with r=11.28 m)
▪ Height percentile metrics: p05, p10, p20, …, p90, p95, p99
▪ Average height of first returns / Average square height
▪ Cover: % first returns above 1.3 m, 5 m, 10 m and 15 m
▪ Structural Variability: standard deviation

Principle Components Analysis
40
▪ PCA was performed on 20 SPL metrics:
▪ FORESTED polygons only
– PCA1 -> 76% of variance
– PCA2 -> 11% of variance
– PCA3 -> 7% of variance
▪ 182 existing plots, incl. 20 IMF plots

Determine Candidate Cells For Sampling
▪ Between 30m and 200 m of roads (90% of existing plots are within 200 m of roads)
▪ Within 200 m of any existing plot accessible via 2x4 truck or 4x4 truck but > 200 m from roads
▪ Remove 100 m wide band around power lines
▪ Keep only cells located within FOR polygon (productive forest stands)
▪ 3,383,903 candidate cells for sampling

Methods to select new plots
42
Minimum distance between samples having the same strata of
500 m
1) Select as much as possible samples located within 3x3
clusters (45/160 new plots)
2) If not enough clusters are available, consider neighbouring
strata in the 3x3 clusters (93/160 new plots)
3) Finally, isolated cells are considered for sampling only if
additional samples are required after steps 1 and 2 (22/160
new plots)
After random selection, inspection of orthoimages and point
cloud:
• Flag plots having similar PC1/PC2 values and located
too close to each other
• Flag plots located too close to a stand border, wetland,
river …
• Flag plots having very isolated trees
