and decay as needed

summer and early fall
• Contractors are used
• Images are the
building blocks of the
Inventory
“Where, when, how & why”
![Page 23: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/23.jpg)

Interpret Aerial Images
Interpretation = Experienced Estimations
• Type areas flown the
previous summer
• Work is done during winter
• Softcopy system is used to
delineate species, age,
height, crown density,
site, and stand boundaries
• Impossible to actually visit
each stand
“Where, when, how & why”

for G &Y, benchmark
the forest state
“Where, when, how & why”
![Page 26: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/26.jpg)
26 April 12, 2013
Field Data - TSPs “Where, when, how & why”
• 10,000+ since FMI began
• Usually areas just
inventoried
• 30 to 60, after PSPs are
completed
• Field 6 two man crews
• New volume info and
to check the quality of
interpretation
![Page 27: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/27.jpg)
27 April 12, 2013
Field Data – Spacing Trials
• 7 trials across the
Island
• 4 year cycle
• 6 treatment, 3
replications
• Growth patterns
associated with
different spacings
“Where, when, how & why”
![Page 28: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/28.jpg)
28 April 12, 2013
Field Data – Ground Truthing “Where, when, how & why”
• In areas currently being
interpreted
• Fall and winter
• A crew travels to stand to
check species, age, density
and site
• Benchmark patterns on
photos with actual stand
conditions

The Future “Where are we going in short term ?”
• Improve P.I. efficiency and quality
Digital Imagery & Softcopy
![Page 31: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/31.jpg)

• Saves time (hopefully)
• we update instead of re-create

• Streamlines line work and attribute
capture
• Enhances access to auxiliary data
![Page 34: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/34.jpg)

The Future – “Where are we going in near term ?”
• Automated Photo Interpretation
Not to replace PI but to aid him
• Lidar ??
Does it have an operational use?
Is it cost effective?
![Page 35: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/35.jpg)

36 April 12, 2013
Conclusion
• The need is timeless
• A lot of data/info is collected
• Technology (softcopy and Lidar )
has potential to aid us
![Page 37: Forest Inventory in Newfoundland and Labrador](https://reader031.fdocuments.us/reader031/viewer/2022011901/61d63b75431f8210ed3eaa97/html5/thumbnails/37.jpg)
37 April 12, 2013
Conclusion
• Must supply something we need
• Must be more cost effective / efficient
than traditional methods
Hope to gain some insight into how
Lidar may address these 2 conditions
Lidar – Operational Use
