• Economical
• Easy to use
• Quality data collection
• Consistency/accuracy

Why Now?

1. Introduction of sUAV

Cell Phone Technology + Lower $$

• Electronic Control System (ECS)
• Accelerometer & Gyroscope Chip
• GPS Chip
• Lithium Polymer (LiPo) Battery
• Motors

Integrated gyroscopic/GPS Chip in 2000's = $10,000

In 2017 = $3

UAV - Unmanned Aerial Vehicle

FAA Definition: Unmanned Aircraft (UA) system that is operated by a pilot via ground control or on-board computer. 

UAV Categories

Small  

• Size: 1 - 2 meters ( 3 ft - 6.5 ft), < 55 lbs. 
• Control: Visual line of sight, Radio control
• DJI Phamtom, 3DR - Solo, Insitu - ScanEagle

Medium 

• Size: Equivalent to a car, ~ 1000 lbs.
• Control: Visual Line Of Sight (VLOS) & Beyond LOS, RC & Satellite
• General Atomics -MQ1 Predator 

Large  

• Size: > 30,000 lbs. 
• Control: Visual Line Of Sight (VLOS) & Beyond LOS, RC & Satellite
• Northrop Grumman RQ-4 Global Hawk ~$222 Million

UAV

Unmanned Aerial Vehicle "Drone"

sUAV as Platform

Multi-rotors

Fixed wings

• Short flight time (< 20min)
• Cover small area
• Highly maneuverable
• Less expensive
• Access to confined spaces

• Long flight time (+ 30min)
• Covers large area
• Larger selection of sensors

 Sensors

Multi-spectral 

Thermal Infrared

Lidar Camera

High resolution digital camera

Workflow

1. Aircraft + Sensor        (Data Collection)

2. Data Processing & Analyzing (GIS)

3. Information Products

||

Benefits

• Temporal Resolution
  • Fly more often

Offer decision makers with appropriate analytic information products

• Spatial Resolution
  • Monitor continuous changes
  • High Spatial resolution than Satellite, Plane
• More Data > More Knowledge > Better Decision Making

Some Commercial Uses

FAA Regulations - Where are we now?

2. Regulations

Commercial/Governmental

1. Section 333 Exemption from FAA

2. SAC - Special Airworthiness Certificates from FAA

King County WTD

"Subject: WTD Policies on Use of Small Unmanned Aircraft Systems (Drones)

Managers/Supervisors: August, 2016

I’d like you to share the following policy guidance regarding the use of drones for work purposes with your staff as appropriate. The guidance specifically addresses the use of drones classified as small unmanned aircraft systems (UAS), which weigh less than 55 lbs."

• No owning or operating drones by WTD
• Manager/Supervisor review and require Division Director approval
• 3rd Party to meet KC Risk Management requirements

Workflow Example 1

Whidbey Island, Langley Downtown example (Spring, 2014)

3. Application Examples & WTD Projects

Flight with Data Collection

• Collected 200 Images
• Using Agisoft PhotoScan to stich images
• Alt. Tool - Microsoft Image Composite Editor (ICE)

Information Product 1- webmap

• Create web-map using GitHub's gh-page

git checkout gh-pages
git add outputfolder
git commit -m "Yes... TILE DATA"
git push

Information Product 2 - OpenStreetMap 

• Using imagery to digitize street, add features to OSM
