UNMANNED AERIAL SYSTEMS: A NEW APPROACH TO REMOTE SENSING QUANTUM SPATIAL PRODUCES DERIVED ANALYTICS USING THE
LATEST TECHNOLOGIES AND MOST ADVANCED APPROACH.
CUSTOM SENSOR FABRICATION COMBINED WITH PARTNER
UAS PLATFORMS, POSITION QSI AS THE INDUSTRY LEADER IN
UAS-ENABLED REMOTE SURVEY AND INSPECTION. OUR UAS SOLUTIONS
PROVIDE COST SAVINGS, DATA PRODUCTS NEW TO THE INDUSTRY, AND
ARE A REALITY TODAY.
During the 2000s, Quantum Spatial, Inc. (QSI) pioneered the collection
of high-density LiDAR point clouds in the rugged terrain of the Pacific
Northwest, capturing millions of acres of national forest and private
land to produce extremely precise ground models. Today QSI adjusts
its approach to fit the requirements of the survey mission. Area size and
location, required data products, accuracies, resolutions, and other factors
are all taken into account to deploy a UAS or drone. QSI is pleased to
offer drone-based data capture solutions for site-specific applications and
corridors alike. In continuation of our vast fleet of traditional survey air-
craft and sensors, we view the use of UAS for remote sensing as a natural
progression for remote inspection in which high resolution data is collected
with a drone.
QSI has designed an array of advanced sensors for inspections and surveys of locations and
infrastructure in challenging locations. Data collection can range from real-time inspections
to high-sensitivity spectral detection with fine-scale spatial mapping. With access to multiple
UAV (Unmanned Aerial Vehicle) platforms, each custom sensor package is mounted to a drone
appropriate for the mission at hand. Precise positioning is accounted for with GPS corrections
from the IMU and Ultra-Wideband radio provides even finer accuracy. The imagery and other data
collected with a UAS provides the information necessary to detect small-scale damage and signs of
degradation, or larger scale physical or structural changes. The information collected by a UAS can
be delivered immediately on-site; and with a degree of added time, QSI can take the data further to
bring valuable analytic insight and business intelligence to your desktop in the office.
UAS ADVANTAGES
• Safety
• Fresh, innovative data products
• Cost savings
• Data is actionable sooner
• Unsurpassed resolution
• New insights from new perspectives
ADVANCED INSPECTION SUITE
Robust datasets acquired from a UAS perspective allow
remote users to see complete digital coverage of sites and
assets. The choice of drone platform depends on the survey
area and project requirements. Drones are chosen based
on area size and location, optimal flight time, and payload
(sensors to be deployed). Multispectral visible imagery
and LiDAR sensors can be mounted on the smallest UAVs.
Hyperspectral systems typically require a more robust and
powerful platform.
A UAS results in more precise and focused data collection
than high altitude fixed-wing acquisition. Data is collected
in proximity and at different angles for imagery and to min-
imize beam-shadow effects in point clouds.

Above: Using thermal information, QSI can detect liquid levels in covered basins or detect system leaks that may not be noticeable to the naked eye at time of inspection. Right: Multispectral imagery (7-bands) can be refined to highlight unseen aspects. Right, Below: Electric conductors were captured in this LiDAR point cloud collected with a UAS.
CUSTOM SENSORS AND DATA SOLUTIONS
Above: Visible imagery collected with a drone in a near-field inspection can identify potential threats: cracks, corrosion (rust), and physical attributes of note.
• Raw Visible Imagery
A camera can collect continuous video,
static or spherical imagery at 1Hz.
This technology is good for real-time
inspection of hard-to-reach places
like utility poles tops, or roofs. Base
imagery of a site can be collected for
a record, and imagery can be further
reviewed using automated processes
for detection of changed features.
- Utility Assets (Electric tower
inspection, Water Districts)
- Private Assets (Oil and Gas, Roof
Inspections for insurance)
- Construction and Infrastructure
(Bridges, roads, large heavy
equipment i.e. cranes)
• Thermal Imagery Thermal data collection can produce informative
data with minimal processing. Imagery collected with
the thermal imager can detect hotspots, identify
thermal anomalies and measure operating tempera-
tures day or night. Final imagery can be time- or
temperature-stamped. A long-wave multispectral
thermal sensor can capture methane absorption fea-
tures and vibrational features of many rock-forming
minerals to determine atmospheric gas optical
opacity, bulk mineralogy and surface temperature.
The instrument design includes spectral dispersion
which allows for fine-tuning spectral sampling to
the ideal bandwidths for both hydrocarbon gas and
geologic analysis. Applications of thermal imaging
include: Solar farm utilities, Water districts, Search
and rescue, Disaster relief, Cell antenna inspections,
and Emergency response.
• 3D Point Clouds - QSI utilizes a small and dynamic
LiDAR sensor for custom-fabrications for UAS. QSI
utilizes the Velodyne VLP-16 with IMU and GPS units
for creating detailed and dense point clouds. Beam
shadowing and point density issues melt away when
a drone is the collection platform, making this sensor
perfect for detailed as-built engineering surveys.
• Multispectral and Hyperspectral Imagery QSI’s multispectral sensors can collect more than 100
distinct bands of data mid-wave infrared spectral
window. Hyperspectral data is a dense collection of
reflectance bands contained in a “data cube” and can
be viewed as a true-color image, any combination of
spectral bands, or as distinct spectra for individual
pixels representing specific spectral signatures. Data
collected can identify differentiable features from
atmospheric water, geologic and biologic surface
features that complicate observations. Multispectral
information can be used to derive tree species or to
identify the presence of rust or corrosion.
