Use of LiDAR in Data Extraction Presented by Dan Allee,
Philip Burkhart, and Lance Yarema, City of Tyler
1) What is LiDAR? 2) How this project started? 3)
What are the applications? 4) Closing remarks and questions Scope of the Presentation
What is LiDAR?
What is LiDAR? LiDAR – Light Detection and Ranging Beams
of light for gathering data
LiDAR can classify • ground • roads • trees •
buildings, etc. What is LiDAR?
An airplane with LiDAR system sends light energy to the
ground where pulse hits the ground then returns back to sensor. What is LiDAR?
The pulses measure how long it takes for light to
return back to the sensor. This creates the variable distance to the Earth. What is LiDAR?
What is LiDAR? LiDAR does not have to use the
direct nadir, but scans at angles. This is taken into account when calculating the elevation.
LiDAR sends160,000 pulses per second creating millions of points of
elevation data. What is LiDAR?
For ground obstruction like tree canopies, the light pulses will
hit the leaves with multiple returns where it eventually reaches the ground. What is LiDAR?
How this project started?
How this project started? City of Tyler was interested in
LiDAR but never pursued due to cost restraints.
How this project started? LiDAR would be ideal where field
data collecting is inaccessible.
How this project started? An opportunity arose in 2014 when
the TCEQ was conducting a dam failure study for lakes and ponds.
How this project started? • City of Tyler - $50,000
(funded by Half Cents Sales Taxes) • State of Texas - $500,000
How this project started? Companies that conducted the project. •Fugro
Geospatial, Inc. – QA/QC •Atkins North America, Inc. - flying • Williams Aerial and Mapping • McKim and Creed
What are the applications?
ArcGIS Pro and ArcScene used to process, explore and display
the LiDAR data
Downtown Tyler was the focus
Terrain City Visualization 2 main themes explored:
Starting with LiDAR dataset
Extract building footprints
Create 2-foot contours
Create DEM and display in hillshade
Overlay hillshade with building footprints
Overlay hillshade with imagery
Visualizing downtown with LiDAR
LiDAR dataset layer in ArcGIS Pro
LiDAR dataset layer in ArcGIS ArcMap
Comparing LiDAR with imagery
LiDAR 3D visualizations of downtown
ArcGIS Pro Type here ArcScene
LiDAR reveals additional detail

Closing Remarks LiDAR is a useful tool for terrain and
surface structure visualization in addition to its initial role in modeling scenarios of hydrological events
