What Are the Benefits of Using a Drone for Surveying?

When it comes to surveying land, traditional methods are rapidly being overshadowed by the innovative use of drone technology. Drones, or Unmanned AircraftSystems (UASs), offer unparalleled precision, efficiency, and versatility, making them an invaluable tool in modern surveying.


Whether it's for topographical land surveys, construction planning, asset inspection or environmental monitoring, drones provide detailed aerial data that enhances accuracy and saves both time and money. This blog explores the myriad benefits of using drones in land surveying, highlighting how this cutting-edge technology is transforming the industry and setting new standards for excellence.



What Are Aerial Surveys?


Aerial surveys involve the collection of geospatial data from an elevated position, typically using aircraft or drones. This method captures detailed and accurate imagery of the land, which is then used for various analysis and mapping purposes. 


Equipped with high-resolution cameras and LiDAR sensors, drones fly over the survey area, systematically capturing a series of overlapping images from various angles. These images are processed using photogrammetry software, which stitches them together to form a comprehensive, high-resolution 3D model of the landscape. LiDAR-equipped drones go a step further by emitting laser pulses to measure distances precisely, even penetrating through vegetation to capture the ground surface accurately. The resulting data is used to generate detailed topographical maps that illustrate the terrain's contours, elevations, and features with remarkable precision. 


Here's a look at what aerial survey services involve:


  • High-Resolution Imagery: Capturing detailed photographs of the survey area.

  • LiDAR (Light Detection and Ranging): Using laser scanning to measure distances and create precise 3D models of the terrain.

  • Photogrammetry: Utilising multiple photographs to create accurate 3D representations of the surveyed area.

  • Multispectral Imaging: Gathering data across different wavelengths for environmental and agricultural analysis.

  • Data Analysis: Using specialised software to interpret and analyse the collected data.

  • 3D Modelling: Creating detailed three-dimensional models of the terrain and structures.


What Are the Benefits of Having an Aerial Survey?


1. Time and Cost Efficiency


  • Faster data collection and analysis.

  • Reduction in labour costs and field time.

  • Cost-effective for large and remote areas.


2. Access to Difficult Terrain


  • Surveying inaccessible or hazardous areas.

  • Ability to cover large and diverse landscapes.

  • Safe and efficient data collection in challenging environments.


3. Early Detection of Potential Issues


  • Identification of environmental hazards (flood zones, erosion).

  • Detection of illegal structures or land use.

  • Early discovery of zoning or regulatory compliance issues.


4. Support for Planning and Development


  • Detailed data for site planning and design.

  • Enhanced visualisation through 3D models.

  • Improved decision-making for infrastructure development.


5. Environmental Impact and Sustainability


  • Minimal disturbance to the environment.

  • Preservation of natural habitats during surveying.

  • Sustainable approach to land assessment.


How much do drone surveys cost?


The cost of aerial surveys in the UK can vary widely based on several factors, including the survey's scope, technology used, and geographic location. Here’s a breakdown of cost considerations:


Survey Area Size - Larger areas require more flight time and data processing, increasing costs.


Terrain Complexity: Difficult or hazardous terrains may require specialised equipment or additional safety measures.


Data Processing Requirements - More complex data analysis and higher resolution mapping will increase costs.


What are the key considerations for drone surveys?


As professional surveyors and structural engineers offering drone survey services, we understand the importance of meticulous planning and strict adherence to various technical, regulatory, and operational factors to ensure successful and compliant operations.


Here are the key considerations we address:


Compliance with CAA Regulations


We obtain all necessary airspace permissions and have qualifications from the Civil Aviation Authority (CAA), including Operator ID, Flyer ID, and Operational Authorisation. If there are any flight restrictions, we stay fully informed about and comply with no-fly zones, restricted areas, and altitude limits.


Privacy and Data Protection


We ensure compliance with the Data Protection Act 2018 when capturing imagery or data, safeguarding personal information and privacy. Out of respect of neighbouring property owners, we avoid flying over private properties without consent and stick to the Surveillance Camera Code of Practice.


Site Assessment


We conduct thorough site assessments to identify potential hazards, access points, and optimal take-off and landing zones, ensuring a smooth operation. There are factors which we can’t control such as the weather so if there are high winds, rain or fog, we may have to reassess and book the survey for a day with better weather conditions.


Safety Protocols


We perform comprehensive risk assessments to identify and mitigate potential hazards, ensuring the safety of our operations. Our drone operators have emergency procedures in place to manage incidents such as drone malfunctions or loss of control.


Flight Planning


Our team of drone operators meticulously plan efficient flight paths to ensure complete coverage of the survey area, optimising data collection. To make sure we avoid battery outages, we plan ahead to avoid interruptions and make sure we are fully equipped for the job.


By addressing these considerations, we ensure that our drone surveys are conducted safely, legally, and effectively, providing high-quality data while respecting privacy and minimising environmental impact.
