PennDOT Teams Up with T3 Global Strategies for Its First Drone LiDAR Road Drainage Project

Flooded roads, traffic disruptions, and property damage are just a few of the detrimental
consequences of inadequate road drainage. That’s why the Pennsylvania Department of Transportation
(PennDOT) takes a proactive step towards safeguarding its roads and infrastructure.

PennDOT recently tackled a project in an urban area, aiming to alleviate standing water and drainage
issues. In their pursuit of an innovative solution, they joined forces with the experts at T3 Global
Strategies. Faced with a smaller project area, dense tree vegetation, and a need for a quick solution, T3
Global Strategies proposed drone LiDAR surveying with TrueView 3D Imaging Systems from GeoCue, a
departure from traditional manned flights.

In a first for PennDOT, they approved the use of drone technology to provide topographic planimetric
mapping data and high-resolution orthophotography. In turn, engineers from PennDOT will use the data
to implement better drainage.

However, a busy neighborhood, pedestrian distractions, and local air traffic will keep the surveying team
from T3 Global Strategies on their toes. See how they navigate these challenges in the next episodes of
Down to Earth- Urban Drain.

“Down to Earth” is a documentary-style reality series that shows how real surveyors collect data and turn
it into real deliverables, despite challenging conditions, hidden dangers, and inclement weather.
In the first episode, the team from T3 plan and fly the road drainage project. Dan Hruska, Director of
Unmanned Aerial Services for T3, sets the parameters for the flight and pilots the drone. Joining him are
Matt Brownlee, Commercial Production Manager, and Justin Brownlee, an Aerial Mapping Technician,
who will each act as visual observers and help ensure mission safety while Hruska flies the drone.
“The task at hand is complex, with airports, helipads, vehicles, and bustling downtown areas to contend
with,” explains Hruska. “We’re looking at two distinct urban regions, one stretching 2.5 miles, the other
spanning 50 acres, calling for a total of eight flights today. It’s a high-stress, high-stakes day, but I’m
thrilled about the challenge. Our goal is clear: employing drone LiDAR and photogrammetry to address
the drainage issues.”

In the second episode, the team heads back to the T3 office to process and visualize the data. Matt
Brownlee utilizes LP360 LiDAR and photogrammetric software to create a 3D point cloud and orthophoto
of the project.

“After we process the data through LP360,” explains Brownlee, “we’ll take it and make stereograms.
From there we’ll digitize all the lines, features, and roadwork, as defined by PennDOT, to create a final
deliverable of the ground surface that their engineers can use to analyze and address drainage issues.”

Martin Sedilko, a Principal for T3 Global Strategies, was instrumental in working with the Pennsylvania
Department of Transportation. According to Sedilko “PennDOT’s decision to choose T3 Global Strategies
for this road drainage project is rooted in our longstanding relationship. We’ve been in partnership with
them since 2013. Last year marked a significant turning point as they approached us for the first time,
recognizing our expertise in drone technology. They sought our assistance for a high-density LIDAR
project, originally planned with a manned aircraft. However, the unique parameters of the area they
wanted to survey made it clear that drones were the more cost-effective choice.”
