Volumetric Survey

Drones can be used to create volumetric models, useful for stockpile measurements, for instance.

Traditional stockpile measurements when using GPS or Total Stations are inhibited by the limited sample data which can be collected. Instead of using a spot grid with a point every 5 metres, a drone can collect a point with a ground sample distance of 1cm creating a much better sampled and more accurate data set.



We Capture RGB, thermal or multispectral images with our cameras. We can also use a drone, automate flight and image-data transfer.



We transform these images into real time orthomosaic maps ready for your inspection and annotation. 



Assessing and improving the quality of your project. The quality report gives a preview of the generated results, calibration details, and many more project quality indicators.

Collaborate & Share

Streamline project communication and teamwork. Selectively and securely share project data and insights with your team, clients, and suppliers.

What Is a Volumetric Survey?

A Volumetric Survey assists with bulk earthworks, excavation, stockpile volume measurement and compaction volume determination.

Engaging a Surveyor to undertake these surveys on stored or excavated material is the most accurate way to calculate volume. It also safeguards against future disputes between developers, builders and contractors when dealing with large quantities of material.

We have extensive experience in Volumetric Surveys for large and small-scale construction clients and environmental agencies. By leveraging the latest in precision survey technology and cutting edge techniques, we ensure our monitoring results are extremely accurate.


Detailed mapping & data capture

Determining the volume of material removed or for fill, in large dig-out sites such as mines, quarries and excavation pits can assist is calculating financial values. It can also be used as a method of progress monitoring – evaluating the volume of material removed over a period of time.

At Comharra Solutions we provide a professional and independent method of pairing production effort and transport capacity, particularly for mine operators who may be moving large volumes of material on a regular basis. 

Safety Improvement

Identify safety concerns in real time, Reduce the time employees and contractors spend on site and in dangerous areas.

In some cases, this information is even more accurate because drone-generated point clouds gather millions of points compared to the hundreds gathered in a ground-based survey.


Multiple sectors

For contractors, civil engineering firms, mining, aggregates, energy, gas, and construction organisations, volumetric surveys (particularly by drone or UAV) represent a highly efficient method of measuring stockpiles.

For organisations involved in environmental research or landscape architecture, our surveys can be a helpful way of identifying the scope and impact of landscape change.

3D Models

Interactive, georeferenced 3D models provide valuable insights. They can be used to conduct calculations and for remote inspections.


Agricultural Surveys

A multispectral drone survey can provide farmers with a wealth of insights.


Visual Surveys

Drones can be used for producing visual surveys. A visual drone survey and drone inspection can be carried out to check powerlines or conduct roof inspections.
