UAVs: Understanding Unmanned Aerial Systems (UAS) and Potential Applications
Doug Zeissner | Bryan Tuschhoff
Agenda
UAV vs Drone System Platform Types Suitability & Capability Regulations Markets UAV Survey Pattern Cost Considerations/Timeframe/Turnaround Michael Baker’s UAS capabilities
What’s in a Name Unmanned Aerial System
(UAS)
Preferred terminology of the FAA.
Aircraft
Payload (Camera…)
Autopilot RC Controller
Ground Station
What’s in a Name
TypesMulti Rotors Fixed Wing
Types of UASMulti 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
SuitabilityMulti Rotors
Video Documentation Bridge Inspection Construction Site
Monitoring (Video) Architectural Modeling Fly Through Animations Stack Inspections Tower / Pole Surveys Site Mapping (< 5 acres)
Fixed Wing Watershed, Site Mapping
(< 160 acres) Land Dev Mapping Construction Site
Monitoring (Mapping) Corridor Mapping
• Transportation • Utility

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).
Regulations
The FAA currently requires a Licensed Pilot as the Pilot In Charge (PIC).
The FAA requires a Visual Observe as well (VO).
Markets
Utilities Corridor Inspection Services, Greenfield Mapping, ROW and Vegetation Encroachment, Substation Mapping and Wind Turbine Inspection
Transportation High Resolution Corridor Mapping, New Construction, Construction Monitoring, Visualization, and Modeling
Land Development Site Development, Topo Mapping, Volume Computations, Construction Monitoring, Planimetric Updates, Asset Inventory, and Visualization
Environmental Waste Monitoring, Spill Monitoring, Vegetation Monitoring, and Sea Grass Monitoring

UAV Survey Pattern
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
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
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 One stop shop includes surveying also
