LiDAR Applications You Can Use

LiDAR. It's a form of remote sensing that has been in use for 15+ years, but is now starting to reach a point of maturity where its applications are plentiful and the costs are realistic.

Transcript of LiDAR Applications You Can Use

LiDAR
What is it?
You have a
3D point cloud.
What fields
could utilize LiDAR?
What's the future of LiDAR?
Light Detection and Ranging (LiDAR)

Similar to RADAR and SONAR
Collects a 3D point cloud
Accurate and Precise
Applications are limitless
Classification
Inertial Mesurement Unit (IMU)
measures a craft's velocity and orientation (roll, pitch, yaw)
Global Navigation Satellite System (GNSS) receiver
Connects to GPS satellites
What do you need to acquire LiDAR data?
Scanner

Sends and collects the laser pulses and saves them with their time stamp
Weather Station
Iowa Real-Time Network
Private Basestation
NOAA CORS

...but no classification!
...Now, what can you
do with it?
Vectorization
Making LiDAR Accurate
Products
Minor adjustments to the data may be necessary.
If scanner is calibrated correctly, proper flight procedures are followed, and IMU and GPS data is processed properly, adjustments should be minimal.
Interact with your data
To some degree...
ALL!
Absolute
Position
Transmission Lines
Roadways
Resource Management
...And More
Agriculture
Canopy heights and biomass totals can be estimated
Forest biodiversity can be modeled
Accurately map coastline to mitigate erosion
Determine appropriate placement of solar panels on rooftops
Wetlands mapping
Autonomous vehicles and obsticle avoidance
Military uses
Space exploration (Mars and the moon)
Floodplain mapping
City modeling
Contour mapping
Change detection
Glaciology
Landslide suseptibility
Detailed DEM, slope, and aspect map
Combine with yeild maps
Determine where more/less high priced fertilizer needs to be applied
NERC 1&2 compliance
Combined with weather data in PLS CADD
Feature coding
More accessible to all those who make use of the data
Mobile navigation
UAVs
Atmospheric composition
Security cameras
Future space exploration
Increased adoption in new fields
3D Elevation Program and National Digital Elevation Program
More powerful software to speed up processing and automation
Handheld devices that allow the general public to navigate their world in 3d
Self-driving vehicles that will be nearly impossible to crash
LiDAR sensors are becoming more powerful, smaller, and lighter
Reduce costs by eliminating the need for pilot in the air
Program a trajectory and let go or pilot from the ground
Access areas that are dangerous or unreachable from helicoptors and airplanes

And, unless you're doing terrestrial LiDAR scanning...
...you're going to need a vehicle to carry it all.
You may also need...

Questions?
Applications You Can Use
Oil & Gas
Railroad
High accurate bare earth DEMs and surface models.
Coupled with magnatrometers and leak detectectors
Vegetation analysis
High consequence areas
Class 3 and 4
Cheaper, as accurate, higher data density, and more efficient than aerial photos and a survey crew.
Drainage mapping
Cross sections
Map anywhere: natural, man made, and hard to access locations.

3d GeoPDFs

Applications designed to sync data in real time with mobile devices

Move beyond just Google Maps and Street View, lidar can assist in a total 3d immersion to explore and navigate from
