9 Where it fits in Surveying

10 What Makes a drone a Surveyor s Tool? Ease of use Ability to commence operation with minimal training Gather useful information faster Portability Carry on luggage size Easily put together and maintainable 1 box solution Price Price zone for surveyors $10,000 to $40,000 + Return on investment

11 What Makes a drone a Surveyor s Tool? Health & Safety Keep surveyors away from harm Maintain worksite operation Replace Dull, Dirty and Dangerous work Solution orientated Fits into GIS/engineering workflow Survey accuracy with fast turnaround Reliability Return on investment Easily repairable or maintained

12 Fixed Wing vs. Rotor Solution Fixed Wing Rotor Cover Large areas quickly minute flights Fully autonomous Easy Launch and landing Pitot tube for atmospheric data Smaller area coverage (stockpiles) Inspection oriented Heavier payload ability Customizable payloads

13 sensefly ebee Lightest commercial UAV system available Hand launched and fully autonomous Multiple payload options Full 3D point cloud & Ortho output

14 Photogrammetric Principles How to Compute 3D Points from Photographs

15 Photogrammetry Overlap and sidelap determine tiepoints Like points visible in 3 or more images create 3D artifacts

16 Photogrammetry 4 flight lines in Pix4D Initial orientations as registered by the IMU/GPS geotags

17 Photogrammetry 5 flightlines in Pix4D Refined image orientations Overlap/sidelap displayed

18 Photogrammetry Refined image orientations 3D points created through pixel / keypoint matching
