Drone Surveying

Spatial Information Industry

The spacious information industry is an industry that produces·manages·distributes the information through various systems and services that are built through being fused and converged with other industries. This form of business is continuously expanding by the development of AR (Augmented Reality) and VR (Virtual Reality) technologies. (Unmanned cars, Unmanned aerial vehicles, Drones, etc.)

  • Ministry of Land, Infrastructure, and Transport had reorganized various systems and policies by March 2018 and announced that they would utilize more drones for public surveying after 2018.
  • The companies that utilized land measurement/ aerial vehicles for surveying showed that they are willing to use drones in the future.

Domestic/Foreign Market Status

  • In December 2014, the revenue of the spatial information industry in Korea was 7.13 trillion KRW, accounting to 58.8% of the total sales (12.11 trillion KRW) throughout the whole business fields.
  • The National Geographic Information Institute estimated that drones could replace 18% (30 billion KRW/year) of the entire public surveying market (165 billion KRW/year).
  • The international spatial information industry is estimated to have a market size of 4.4 billion USD (based on GIS). When applying the business to a more extensive range, the market size is estimated to be 400 billion USD. (Worldwide Spatial Information Industry Field, National Spatial Data Infrastructure Portal).
  • The spatial information industry is continuously growing.

Drone Surveying

  • Difficulty in concluding the accuracy due to the errors accumulating during each process
  • The probability of personal error is high
  • Shorter Process
  • Eliminates the possibility of error due to data misinput
  • Real-time survey to ensure the accuracy of DB
  • Absolute surveying to secure performance evaluation

Surveying Drone

  • Applied VTOL(Vertical TakeOff and Landing), doesn’t need a separate runway or access area due to the application of VTOL.
  • Collision Avoidance System
  • Straight Wing Type

Related Laws

This Ministry of Land, Infrastructure and Transport had announced safety standards and approval procedures for night flight and special flights in non-visible environments in the second half of 2017. (Article 129.5 of the Aviation Safety Act)

Safety standards and approval procedures for special flights of UAVs
(related to Article 4)

ClassifyMain Components
Commons RequirementsObstacles in landing and flight paths must not affect flight safety
Must equip Fail-safe device
Must equip collision avoidance feature
Must equip a separate GPS location transmitter to transmit location information when a crash occurs
Must prepare and maintain an emergency manual which includes emergency contact & reporting systems in cases of emergency, Also, all participants must undergo emergency training in order to respond properly in the case of an emergency situation
Detailed RequirementsNight FlyingAt least one observer should be placed to keep track the UAV during night flights
Must install an anti-collision lamp that can be recognized from 5km away
Anti-collision lighting must use ‘permanent light type’ and installed in locations where they could recognize in all directions.
Must equip auto-flight mode
Must equip FPV which uses an infrared ray camera
Must install a ground lighting facility and a searchlight at the landing pad.
Invisible FlightsAt least one observer must be located in the planned flight path to identify the UAV when the UAV is flying beyond the visibility of the pilot
Communication must be possible between the pilot and the observer to ensure a steady operation of the UAV
The pilot must check the pre-planned flight path, and the UAV must be capable of manual/automatic/semi-automatic flight
The pilot must ensure before the flight that the CCC (Command, Control, and Communication) equipment is usable within the planned flight range
The UAV must be programmed with the flight plan and the profiles of emergency situations
The UAV must be able to notify the pilot in case of a system malfunction
Communication (RF communication, LTE communication backbone network usage, etc.) must be dual-path
Display the state of the UAV on GCS. GCS notification and external pilot notification in case of abnormalities and failures
Equipped FPV (First-Person View)
