Doug Zeissner and Bryan Tuschhoff, of Michael Baker International, present "UAVs: Understanding Unmanned Aerial Systems (UAS) and Potential Applications" to ASCE OC on December 10, 2015.
6. Types of UAS
Multi Rotors
Strengths
• Vertical takeoff
• Hovering capability
• Camera gimbals
• Simple to fly manually
Considerations
• Short flight times (<20min)
• Hard landing with fail
• Low payload weight
Fixed Wing
Strengths
• Hand launch
• Long flight times (>40min)
• Loiter capabilities
• Soft Landing with fail
Considerations
• No payload stabilization
• Glide to loss with fail
• Best in programmed flight

10. Regulations
The FAA is beginning to allow UAS operations
This is a two step process
Must file a Petition For Exemption under Section 333
Must apply for and receive a Certificate of Waiver or
Authorization (COA).
11. Regulations
The FAA currently requires a
Licensed Pilot as the Pilot In
Charge (PIC).
The FAA requires a Visual Observe
as well (VO).

14. Typical Costs
Acquisition costs
• UAS have lower operating costs when compared to
conventional aircraft
• UAS can be mobilized at a lower cost than
conventional aircraft
Processing costs
• Mapping costs per acre are lower
• As project size increases economies of scale tip
toward conventional acquisition means…fewer
images to process over a larger area
15. Timeframe/Turnaround
Due to typical UAS project size, advances in
processing technology, and depending on the
deliverable…data can be delivered much faster.
Sample Turnaround times with out control
• Video – Real Time
• Imagery – Within Hours
• Raw Semi Globally Matched (SGM) Point Clouds and
Ortho mosaics – Under 24 Hours
• Planimetrics, Contours - * Based on project size
16. Michael Baker’s UAS Capabilities
Designed for aerial mapping of small to mid
sized projects.
Rapid deployment
Fully backed by 75 years of mapping
experience.
ISO certified LiDAR processing
