Diablo Dam: Drone Survey
ADVANCED VEGETATION MANAGEMENT TECHNIQUES AND TOOLS
Today – It is easier than ever to collect vast amounts of high-quality survey grade data through LIDAR acquisition.
Manual Remote Automated
• Cyclical Pre-Determined Route
• Visual inspection• Routine Trimming
• Drones• Manned Aircraft• Laser scanners
• Drones• Automated workflows• Artificial intelligence
Workflows evolution over time
Objective is to turn data into actionable decisions
Data
Knowledge
DecisionsActions
LiDAR (Light Detection and Ranging) Rapidly sends out pulses of laser and then
measures the time of return to generate x,y,zvalues for point cloud creation.
Results in billions of points and a high resolution model of current conditions
Requires large areas for storage of big data sets.
Processing/Classifying is required after collection for optimal use.
LiDAR Data
Collection Phaseo Collect all visible vegetation around and near transmission or
distribution asset. Swath typically 500-1000’ Methodology
o When possible, flight team will generate automated flight plans. Will fly manual… otherwise.
Deliverableso Seamless georeferenced (orthomosaic) image of assetso 3D Point cloud model of dam

AVAILABLE SENSORS
• RGB – Standard Cameras• LiDAR• Multi/Hyperspectral Imaging• Thermal
LiDAR Data Can Be Recycled Throughout the Organization.
LiDAR and other Data Sets Build Upon Eachother Over Time.
Other LiDARUses
Hyperspectral Cameras can help identify both species and vegetation health.
Important for identifying danger trees and anticipated growth rates
Requires indexing of vegetation at specific locations prior to doing a wide area collection
Computationally Complex as well as Data size can be challenges
Hyperspectral Imaging
LiDAR Collection/Processing – Typically ~$1,000.00/mi.
Hyperspectral – Can be collected simultaneously as LiDAR with manned aircraft and some larger drone platforms. Similar in cost to LiDAR.
RGB – Photogrammetric data collection can be done for $200-300/mile but is not recommended as a vegetation management tool by itself. Photogrammetric recreation of treed areas is problematic and ground control can be expensive.

Future Uses
Future Uses:Hydraulic Modeling, Uplift Analysis, 3D Models, Change and Anomaly Detection and Additional Data
Acquisition Technologies (e.g. piezometers, additional survey, seepage, GPR, leakage) can be integrated into the 3D models to develop a holistic picture.

So what’s the problem with 3D data?

www.pointerra.com 16
Problems across the enterprise in using and leveraging costly but valuable 3D Data Viewing – Massive 3D datasets can’t be easily viewed Storing – Unmanageable files often isolated on local hard drives Search – It’s hard to find it if you can’t see it! Cost – High investment in IT, GIS and people just to provide access Delay – Time and cost gap between acquisition and use Usefulness – Efficacy of derivative (dumbed-down) 3D point cloud products Efficiency – Unnecessary repeat scans when data not readily accessible Strategy – Difficult to be strategic about data acquisition
