When you first hear about drones, probably the first thing that comes to mind is photography and videography because they are the most popular uses. But drones are finding more use cases in other enterprise sectors such as surveying and mapping, and Sugu Drones can help you get started.
How Drones Are Used In Surveying
Some of The Data You Compile Using Drones
Drones help in photogrammetry, where they can help capture images which you can then use to take measurements and conduct volume calculations later.
Drones can also help produce outputs such as orthomosaics, Point Cloud classifications, Digital Terrain, and Surface Models 3D models, all of which provide an accurate representation and interpretation of the object on the ground for use in mapping, engineering, architecture, quality control, among other areas.
Why Use Drones In Surveying And Mapping
In traditional photogrammetry, aerial images used to be collected using airplanes and helicopters. While it is effective, it is expensive and time-consuming, especially when there’s an error. You’d need to reschedule for another field day to recollect the data. Another issue airplanes present is the risk to human life, in this case, the pilot or anyone around where the plane is flying. In case the plane crashes, the casualties will be more fatal.
Drones make it easier in several ways. For starters, automating the data collection process is now easy by giving the drone waypoints to follow. This also helps minimize the errors.
Secondly, drones have GPS, so the images collected will have a spatial phenomenon or be georeferenced. You could argue that a drone’s GPS may not be accurate enough to collect data for surveying and mapping, but there are ways to correct the data by establishing GCPs (Ground Control Points).
Besides, there are drones designed specifically for surveying and mapping, and they’ll have an RTK or PPK, which are more accurate.
Thirdly, drones are cheaper to run. For as low as $4100, you can get a DJI Phantom 4 RTK or an Autel Evo II PRO RTK drone, which will effectively collect the data you’ll need. That’s manageable compared to the costs of running a plane. Not forgetting that planes have a longer checklist before they are allowed to fly compared to drones.
And lastly, drones are safer. The drone pilot flies it from the ground, and the damage a drone can cause if it crashes may not be as fatal as that of a plane.
Getting Started With Drone Surveying And Mapping With Sugu Drones
Students Participating In The Remote Sensing Course
Now that you know what drones can do for you regarding mapping, it’s time to do it practically. But if you’ve not done it before, you may not know how to start. Learning it on your own is also hectic, time-consuming, and may not always be fruitful. Therefore, eliminate the guesswork and come and learn from Sugu Drones, a leading drone flight training institution in Canada. Sugu Drones has a comprehensive Remote Sensing Course that teaches the following;
· How to acquire images for remote sensing.
· How to mission plan and map using an Autel or DJI drone.
· How to process your data using Drone Centre, a platform Sugu Drone uses to compile data and present it in a viewable form.
· Survey application.
· How to further process and present your data using QGIS.
· Drone Maintenance tips for winter.
And there you have it. Come and learn from the best how you can leverage drones in your workflow for surveying and mapping. There’s a lot more you can do with drones in surveying and mapping, and this course from Sugu Drones helps points you in the right direction.
