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 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
