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

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).

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
