4 Prolifera6on of Tech in SSH LiDAR data and analysis to pick out opportunities for single-stem and/or heli-logging based on canopy height models. ios apps - Climbers, fallers, ground crew and heli pilots using Apple technology (iphones and ipads) to store map and data (and sometimes navigation). On-the-spot calculations for volume estimates and tree ID Pin heli-pads, hazard trees and other items to be efficient in the field ESRI's spatially-referenced Collector app - collect, input, store and change data through various phases of single-stem projects. GPS technology and rangefinders for fixing, tracking and mapping absolute and relative positions of targets, features and hazards.

5 The latest with LiDAR Saving time, maximizing investment in LiDAR through better analysis Classifying the forest in greater detail Species identification now more reliable Automated feature capture = less processing time, cost savings

6 LiDAR Light Detec?on And Ranging Standard DEM compared to LiDAR

7 UAV Enabled Planning What benefits can we see? Cameras & sensors for our UAVs What do we end up with? Comparing UAV datasets

8 Benefits Higher resolution = more precise planning Ability to quantify the study area Easily compare blocks over time 3D products to help with planning See the site in 360 degrees Multiple uses of new datasets (eg forest health indicators) Quick to mobilize UAVs Lower cost than traditional flights with equal or better results

9 UAV cameras and sensors RGB (true color) Multispectral (includes NIR) Thermal infrared Hyperspectral LiDAR

10 UAV cameras and sensors RGB (true color) Map study area over time Track growth, assist with FTG surveys Generate 3D point cloud with results Create orthophotos with ability to measure distances +areas

11 UAV cameras and sensors Multispectral (includes NIR) Map forest health over time Includes Near Infrared and Red Edge Measure of plant greenness, with healthy vegetation highlighted Distinguish slash, NP and growing areas easily

12 UAV cameras and sensors Thermal infrared Map relative or absolute temperature across your study area Assist with wildlife inventories and habitat mapping Map drainages not detected by traditional imagery Many other uses (Hotspot mapping for wildfire)

13 UAV cameras and sensors LiDAR Detailed canopy height models Calculating stems/ha & other metrics Accurate bare earth models (DTMs) Powerful for 3D visualization All of the same benefits we see with traditional flights

14 UAV cameras and sensors Hyperspectral >10 bands to work with, can be hundreds Many more formulas can be applied to your UAV imagery Assess drainage issues, pests, nitrogen deficiencies and other problems easier
