DATA

GIS Data:
The core of a GIS is its Database

BUT.....There are 17 county agencies support

King County GIS Data Library System

WTD

GIS Data:
The core of a GIS is its Database

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

In 2017 = $3

1981 $120,000

2013

$5 - $15

In 2025 = $3 (??) less than $1

  • Price /Performance
  • Easy to use
  • Quality data collection
  • Adopting Rule by FAA

Why Now?

Cell Phone Technology + Lower $$

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

RPAS - Remotely Piloted Aircraft System

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

What's in the name?

UAV = Unmanned Aerial Vehicle

UAS = Unmanned Aerial System

DRONE = Dynamic Remotely Operated Navigation Equipment

RPAS = Remotely Piloted Aircraft System

RPAS Categories

Small  

  • Size: 1 - 2 meters ( 3 ft - 6.5 ft), < 55 lbs.
  • Control: Visual line of sight, Radio control
  • DJI M3E, M400,  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

FAA Regulations - Where are we now?

Regulations

Commercial/Governmental

FAA Part 107 Rule, July 2016

  • Need FAA Remote Pilot Certification (Pilot license NOT needed)

  • ~460,375 - Remote pilots certified (Oct. 2025)

  • 433,407 - Commercial Drones Registered (Oct. 2025)

  • $175 to take the test
  • Fly under 400 feet above ground level

  • Not to fly < 5 nautical miles around airport

  • Aircraft < 55 lbs.

  • Fly during daytime or night time operation with appropriate lighting

  • Fly visual line of sight ( VLOS)

  • No flight over non-participating people

  • ...and many, many more.....

FAA Part 107 Rule

  • Be at least 16 yrs old

  • Pass the initial aeronautical knowledge exam

  • Online recurring training every 24 month 

  • Understand recreational flying requirements

  • Take TRUST

  • Online recurring training every 24 month 

Hobby/Recreation

  • Self register (over 13 yrs old)

  • Fly under 400 feet above ground level

  • Not to fly < 5 nautical miles around airport

  • Aircraft < 55 lbs.

  • Fly during daytime

  • Fly visual line of sight ( VLOS)

  • Less than 250 grams (0.55 lbs)   - No need to register with FAA
  • More than 250 grams register with FAA $5.00

RPAS as Platform

Multi-rotors

Fixed-wing & VTOL

  • Shorter flight time (< 45 min)
  • Cover smaller area
  • Highly maneuverable
  • Less expensive
  • Access to confined spaces
  • Long flight time (+ 40min)
  • Covers very large area

(vertical take-off & land)

Two Spaces for Drone

Outdoor

Indoor

Outdoor

  • GPS Signal
  • Automated Planning and Flight
  • Even, Diffuse lighting
  • Open space

Indoor

  • No GPS signal
  • Limits on speed and motion
  • Manual flight control
  • Tight spaces
