Drone Survey Types

Do you know about the various types of drone surveys? Or that those surveys are literally reshaping a couple of industries across the globe? Well, today’s blog focuses on the diverse types of drone surveys and how they improve efficiency and accuracy. Make sure to read the blog till the end to equip yourselves with insightful information.

What is a Drone Survey?

A drone survey is a survey that is conducted by utilizing a drone or an unmanned aerial vehicle (UAV). By using drones, the surveyors can access aerial data using downward-facing sensors. These sensors can either be RGB* or multispectral cameras, and LiDAR** payloads. Such surveys provide access to data which is not too easy to access otherwise.
  • Red, Green, Blue colours of light
  • Light Detection and Ranging
Several industries benefit from conducting drone surveys. Such as agriculture, mining, construction and environmental monitoring. In addition, infrastructure inspection can also be performed through drone surveys. We would also like to mention that drone surveys also help in urban planning as well.

Types of Drone Surveys

Types of Drone Surveys
Drone surveys have not only revolutionized conventional surveying methods but continue to facilitate accurate data collection. Let’s explore the various types of drone surveys in this part of the blog!

1. Orthomosaic Surveys

An Orthomosaic survey is conducted by using a drone-mounted camera. This survey involves capturing multiple overlapping images of the area that is being surveyed. Once the survey has been conducted, the images are stitched together. This process is completed by utilizing specialized software that creates a high-res, georeferenced Orthomosaic map. An Orthomosaic survey offers a highly detailed representation of the landscapes. The collected data offers invaluable insights for urban planning, infrastructure development and more.

Allow us to also mention that you can get two types of maps by conducting Orthomosaic surveys:

  • 2D Orthomosaic Maps
  • 3D Orthomosaic Maps

2. Topographic Surveys

Topographic or Topo surveys are conducted to understand Earth’s terrain, including the natural and man-made features. Topo surveys are helpful for the construction and architecture industries. In addition, these surveys are indispensable in land management as well as infrastructure development. We must also mention that Topographic surveys enable all the stakeholders to make informed decisions when it comes to urban planning.

3. Thermal Surveys

To conduct a Thermal survey, drones with infrared cameras are utilized to collect data. And the data that is collected is basically the temperature variations in and around the land that is being surveyed. Thermal surveys are quite beneficial for precision agriculture, building inspections as well as rescue operations. In addition, Thermal surveys also help with building inspections for informed decision-making.

Thermal surveys are instrumental in the identification of energy leaks and crop stress. Once the surveyors find thermal abnormalities in a surveyed area, they can take proactive measures for risk mitigation.

4. Cadastral Surveys

Cadastral Surveys
The name’s interesting and so is the survey itself. Here’s what is meant by a Cadastral survey:

This survey is performed to map and delineate land boundaries and property parcels. The drones that are used to conduct this type of survey are equipped with GPS receivers and high res. cameras. By making the most of modern equipment, the surveyors can get their hands on accurate and detailed cadastral data. Cadastral surveys are usually performed to determine real property’s metes-and-bounds of a country. If the goal is to achieve transparency in land administration, then Cadastral surveys are the solution.

Among the various benefits of Cadastral surveys, we must also mention that the collected data facilitates dispute resolution among authorities.

5. Hydrographic Surveys

The drones that are used to perform Hydrographic surveys are equipped with sonar or bathymetric sensors. These sensors are basically utilized to map underwater features including rivers and coastlines. In addition to that, Hydrographic surveys can also detect submerged structures present under the water. If you’re wondering how these surveys help the surveyors in the long run, then continue reading the blog. Hydrographic surveys are crucial for hydrological research, marine engineering and coastal management. Furthermore, these surveys provide insightful information for navigation safety, habitat mapping and dredging operations.

6. Vegetation Monitoring

Drone surveys are quite helpful when it comes to vegetation monitoring – facilitating the agriculture sector. The drones that are used to perform vegetation monitoring are armed with multispectral or hyperspectral cameras. The purpose of those cameras is to collect data in areas that are not accessible to the human eye.

Now, what happens after vegetation monitoring is that farmers and other stakeholders can analyze plant / crop health. In addition, they can also manage species distribution by considering environmental challenges and related hazards. We must mention that various sectors benefit from vegetation monitoring such as:

  • Agribusinesses
  • Forest management authorities
  • Environmental scientists and ecological researchers

7. Environmental Monitoring

Speaking of vegetation monitoring, we would also like to share that drone surveys are also helpful in environmental monitoring. What happens in this type of survey is that the natural ecosystems are monitored. And in addition to that, environmental scientists can also monitor air quality and pollution levels. In addition, wildlife habitats can also be inspected to protect the endangered species.

By utilizing the data collected through environmental monitoring, the concerned authorities can help in issuing early warnings regarding potential ecological disruptions.

8. Volume Calculations

It’s a fact that drone surveys serve many different types of industries and businesses. Allow us to share that drone surveys are also beneficial for extensive volume calculations. Volumes of materials are usually calculated in areas such as construction sites and factories. In addition, stockpiles and quarries are also to be monitored where necessary.

Volume calculations are conducted by using LiDAR data from different angles. The collected accurate data can be in the form of calculating the volume of sand, gravel, etc. Facility managers can then utilize the information to streamline inventory while the rest of the stakeholders can improve project monitoring.

Having shared the multiple drone survey types, we would now like to share a couple of advantages of performing them.

Key Advantages of Conducting a Drone Survey

If you’re reading this, there’s a very high chance that you are not too sure about performing a drone survey. And that’s okay! To make it easy for you, we want to mention the key advantages of drone surveys to help you get started. Continue reading the blog so that you know what you are getting into.

Drone Surveys Are Cost-Effective

First things first; know that drone surveys are super cost-effective yet accurate. Unlike traditional surveying methods, performing aerial surveys won’t put a dent in your pockets. That’s guaranteed – mainly because you won’t have to hire a dozen people to get things done. In addition, drones are capable of monitoring larger areas; that too efficiently.

Drone Surveys Are Time Efficient

Every project has a timeline to follow, right? What if we told you that performing a drone survey will also contribute to efficient project management? Well, you read that right! Drone surveys make the process of data collection quicker and more efficient. When you get access to the required data that meets your timelines, you experience faster turnarounds too.

Drone Surveys Ensure Safety

Drone Surveys ensure safety

Ensuring the safety of the team members is crucial for any project. Drone surveys majorly contribute towards safety concerns as compared to conventional surveying methods. When drones are utilized to conduct surveys, the surveyors can capture data from a safe distance. So, it is safe to say that drone surveys ensure project success by enhancing safety for surveyors.
