What is drone surveying?/What are the benefits of drone surveying?

 Let us go through some of the FAQs related to drone surveying.

1. What is a drone land survey?

A drone survey is an aerial survey to capture the aerial data of a survey land from different angles. Drones are fitted with multispectral cameras & sensors. 

The drone survey provides us with numerous digital prints of the site. Each image is linked with the coordinates so that we can process & create detailed 2D & 3D maps.

2. Is the drone land survey accurate?

Yes. The drone flies at a lower altitude to capture high-resolution data. Several images are taken from different angles & they are overlaid to form the final data. So, there is no scope for errors in the survey maps formed by the drone survey. 

In a traditional survey, we come across human & instrumental errors. But as drones are unmanned data collectors, we find them more accurate & much faster.

3. What are the benefits of drone surveys?

1. Reduces working time: 

A traditional survey takes several days or even weeks to complete the work. The same task can be completed within a few hours in drone surveying.

2. Less manpower:

A drone survey does not need surveyors or more people to do the job. The data can be collected much more quickly & efficiently, that in turn saves the operative manpower.

3. Cost-effective: 

Drones can be used as & when required to capture data. Drone survey saves us extra time, and required manpower, & hence they are cost-effective.

4. Provides accurate data:

The drones can produce thousands of measurements captured from all angles. So there is less scope for errors when compared to manual mistakes or errors in traditional surveying. 

5. Accessibility:

The drone can fly into all the nooks & corners of our earth to collect data. In hilly areas & terrains, where manual reach out is impossible, drones are the best options for the survey work.

6. Tracking progress:

By using drones, we can capture snapshots of the land at various stages of ongoing work. They can be flown at required intervals to keep an eye on the day-to-day progress of the project work.

7. Safe to work:

 In traditional surveying, the workers are put at risk while accessing difficult areas. There are no such safety issues while we carry the drone surveying. Hence they are safe to work in all such unreachable topographical regions.

8. No dispute:

A drone survey provides visualized data so that non-surveyor can understand the work progress. Due to this visual source of information, there is no chance of disputes between the two parties.

4. How much does a drone survey cost?

The cost of a drone survey depends upon the type of survey & time involved in completing the job.

However, the general cost of the drone survey 👇

Per acre cost 👉  INR 2000/- to INR 10,000/- 

Per hour cost 👉  INR 1500/- to INR 5000/-

5. How does a drone survey work?

The drone survey uses geo-references & ground control points to create a data set. The aerial mapping incorporates ground control points in its high-accuracy images. This process of compiling data in the survey work is known as photogrammetry. 

The GNSS & GPS system is used for references to check the ground control points.

Drones are equipped with laser or lidar distance sensors, multispectral sensors, navigational systems such as GPS, altimeters, thermal sensors, etc.

 Once the images are captured from different angles, the compiled data are processed by software to create 2D or 3D survey maps.
