Drone surveying and traditional surveying
Advantages of Surveying with drones0:01
Advantages of using drones for Survey
Survey accuracy and Ground Sampling Distance2:53
Ground Sampling Distance
Which drone is best for the job?3:04
For surveying, favor DJI Phantom 4 or Mavic Pro 2 due to best value and seamless integration with third-party flight planning and data processing software.

What is a flight plan?1:16
Parameters for flight planning
Nadir and oblique images1:10
Nadir and oblique images
Flight planning off site versus on site0:58
Tagging GPS way points of site boundaries3:59
Creating kml file from excel3:13
Convert an Excel GPS file to a KML by importing latitude and longitude into Google Maps, creating placemarks, exporting as a KML, and viewing in Google Earth.
Creating nadir image capture flight plans9:10
Overlap
Creating multiple capture flight plans for larger sites5:42
Multiple nadir flight plans for a project
Creating oblique image capture flight plans6:52
Plan oblique image flights with the Litchi app to capture 3-D reconstructions, creating waypoints around the building, a central point of interest, and a 2-second interval.
Which of the following statements is FALSE regarding flight planning

Safety and regulations6:17
Equipment and app check list4:33
Ensure full equipment readiness for drone surveys by following a comprehensive preflight checklist: maintenance, batteries, cables, takeoff pad, safety gear, and essential apps (DJI Go, Drone Deploy, Litchi, GIS Essentials).
Marking boundary points4:15
Mark boundary points with visible markers before flight so they appear in the orthomosaic and can be overlaid as a boundary layer in autocad.
Choosing the best take off point2:41
Select a take off point with at least a 5 meter radius of clear, unobstructed land near the flight plan center to optimize battery life and maintain signal.
Adjusting flight parameters based on site conditions1:57
Adjust on-site drone surveys by changing take-off points, altitude, and overlap (not below 70%) to handle obstacles and conserve battery, ensuring the survey completes.
Drone flight Parameters
Nadir image capture with DroneDeploy4:54
Calibrate the drone, set up a DroneDeploy flight plan, and execute nadir image capture with GPS-driven waypoints, then verify image coverage and perform a safe return and post-flight checks.
Image quality and coverage check2:04
Remove the drone's SD card, connect it to a laptop, and perform an image quality and coverage check for blurriness, overexposure, and missing areas, then upload to dronedeploy.
Planning additional flights2:17
Create a new flight plan by copying the original, trim it with white dots to cover the missing image section, adjust lines, then save and sync to the mobile app.
Return to Home and Continue Flight0:55
Identify when to return to home during a mid-flight drone survey, then continue flight after battery changes, using distance and remaining battery as guiding factors.
