Popular Drones
Things to Consider
Ground Measurements
• Needed features/functions• Initial equipment costs•
Maintenance plans• Annual subscription fees • Operation training +
costs
• LTI Lasers• Total Stations• GPS
Hardware Options
• DJI• Aeryon Labs / Flir• Yuneec• Dragon Fly

Flight Patterns and Photographic Techniques
-
Grid Double Grid Circular/Orbital
Patterns
GRID: 2D Map outputs (Orthomosaic). Fly a Nadir rectangle
mission.
DOUBLE GRID: 3D Map/Model outputs (Point Cloud data, Mesh).
Vertical Details.
CIRCULAR: Ellipsoid flight around objects. High objects. Several
circular missions at different altitude. 3D Output
FREE Flight: 2D and 3D outputs (Orthomosaic / Point Cloud).
Complex projects require more flexibility. Vertical Details.
Free Flight
-
• 5 to 8 per project (More if needed for larger area)
• Random – Well distributed(Not bunched together)
• Center and near the edges(But Not ON the edges)
• Viewable from multiple images
• Unobstructed and clearly visible
• NOT in a straight line
• Near features of interest

Photo Techniques
• Nadir images with high overlap will help ensure greater
accuracy in your mapping output.
• 2D Output Orthomosaic• Flight style: Polygon, Grid, Free

FAA Regulations
Commercial Drone Pilot License Required• Any flight for
commercial use • Compensation for you• Benefits another
business
FAA Airman Knowledge Test • Taken at local FAA Testing Center•
Shorter version of traditional private pilot ground school• Test:
60 Questions (2+ hours long)

FAA Regulations
UAV Operation Rules• You may not operate a UAV over any person
who is not either
directly participating in its operation, or who is not located
under a covered structure that can provide them reasonable
protection from a falling small unmanned aircraft.
Visual line-of-sight (VLOS)• Visual line-of-sight (VLOS) only;
the unmanned aircraft must
remain within VLOS of the remote pilot in command and the person
manipulating the flight controls of the small UAS.
-
FAA Regulations
Restricted or Prohibited Areas
• You may not operate in restricted or prohibited areas without
first obtaining permission from the using or controlling
agency.
• No person may operate a small unmanned aircraft in Class B,
Class C, or Class D airspace or within the lateral boundaries of
the surface area of Class E airspace designated for an airport
unless that person has prior authorization from Air Traffic Control
(ATC).
