Aircraft & Sensor Selection Flight Planning & Execution Processing Software

• Safely and successfully mapped thousands of acres throughout Colorado since early 2015
• The Aircraft, the Sensors, and the Processing Software all matter when preparing precision mapping
• As accurate as you can get using the best available UAS technology.
• A few Key Components to Successful Precision Mapping Include:

Flight Management Systems

Typical Features:

6/27/2019 11

Construction Monitoring Cut and Fill Analysis

Aerial Photography and Videography

• Generated with consumer grade drones;
• Very little flight planning, processing, piloting, and GIS experience required;
• No surveyed ground control required.

Standard Applications

6/27/2019 12

Topographic Mapping LiDAR Mapping Virtual Reality

• Generated using advanced sensors, professional grade platforms, and surveyed ground control.
• Surveying, data collection, processing, and GIS experience required.
• Products are geolocated in state or local coordinate systems.

Advanced Applications

Superior Data as compared to Traditional Ground and Aerial Surveys

• Topographic Mapping at a 1-foot

Contour Interval

• Horizontal and Vertical Accuracy is

at or near Survey-Grade, which is 0.1-foot horizontally and vertically

• High-Resolution Orthomosaic

Image w/ 1” Pixel Resolution

• 3D Point Cloud with 24,027,418

Points with each Point Representing 1 square inch on the Ground

• 4k Video

All mapping was georeferenced and delivered in the Ralston Coordinate System

Northwater Treatment Plant Engineering Grade Deliverables

6/27/2019 15

Superior Data Quality

As Compared to Traditional Aerial and Ground Surveys

3D POINT CLOUD

• UAVs vastly reduce data capture costs and appreciably increase data quality and richness
• Point Cloud Contains 222,319,447 points
• Provides a Compete Representation of the Ground Surface

6/27/2019 16

WCE Compatible Workflows

• We don’t simply collect and deliver data.
• As engineers we can post-process the data and deliver it in virtually any format, and any

coordinate system.

• This is what sets us apart from other traditional UAS operators

Buyer Beware

Drone Operator Capability

• Not All Operators are Capable of Producing Engineering-Grade UAS Mapping
• Multi-million Dollar Construction Projects Demand the Best UAS Mapping Available

Multi-million dollar design and construction projects demand engineering-grade UAS Mapping
