ó GIS mapping company specializing in UAV operations ó Located in Nanaimo, BC, Canada ó Clients include: ó Local, Provincial and Federal Governments ó Resource Industry

ó Current Forest Inventory Practices ó Flight Operations ó Processing ó Forest Inventory Creation

ó Required extensive pre –harvest inventory ó Timber Cruise ó Survey crew of two or more ó 100 meter by 100 meter grid within block ó 3.99 meter radius at each point within grid

ó Time Consuming

ó Expensive

ó Hazardous

ó UAV: Aeryon SkyRanger/Scout ó Grid Parameters ó Flight Level: 120 meters ó Image overlap: 80 front-lap x 60 side-lap ó AOI coverage

ó Environmental factors ó Geographical factors

ó Forestry Cut-block grid flight design

80% Front-lap

60% Side-lap

ó Ground Control Points Collected ó Sample Tree Heights ó For Comparison purposes only ó Spaced throughout AOI ó Clinometer/Tape Measure

ó Any other required points

ó Sample Tree Height Calculation ó Processing UAV Imagery ó Post Processing ó LAS Classification ó DEM/DSM Extraction ó Tree Height Calculation and

Inventory Creation

ó Use trigonometry to calculate tree heights Flat Surface

Downhill

Uphill

Height of Tree = h + B x tan(A) h = height of surveyor B = distance from base of tree A = clinometer angle

ó Input into Pix4D ó Ground Control Points

used to “tie down” resulting product

Ground Control Points

ó Using LAS Dataset toolbar and 3D Analyst ó Classify LAS as ground(2) or vegetation(3)

LAS Dataset Profile View

LAS Dataset 3D View

ó Convert LAS to Raster DEM/DSM ó LAS to Multipoint ó Multipart to Singlepart ó Topo to Raster

ó Canopy Height Model (CHM) ó Raster Calculator ó CHM = DSM – DEM

ó Create Value Attribute table (VAT) ó Raster Calculator ó Multiply CHM by 1000

ó Int (Spatial Analyst) tool ó Convert CHM to Signed Integer

ó Extract 99th Percentile ó Slice tool ó 100 Equal Interval Classes

ó Raster to Polygon ó Retain 80th Percentile value

ó Convert to Point Feature ó Extract By Mask ó Raster to Point

ó Remove 99th percentile from CHM ó Con tool (Spatial Analyst) with extracted 99th percentile ó Replace with NoData

ó Iterate process until 80th percentile value reached

ó Create Forest Inventory ó Near tool (Analysis) ó Group points within approximate radius of tree ó Keep point with highest cell value

ó Tree Height ó Field Calculator to divide by 1000 ó Reset values to original significant figures

ó QUALITY ASSURANCE ó Compare tree heights in newly created inventory with

sample tree heights gathered in field.

ó If heights are within 5% then SUCCESS!! ó According to Cruising Standards-Ministry of Forests, Lands

and Natural Resources
