Virtual Surveyor


Powerful analysis and visualisation of your drone surveys. Virtual Surveyor is ideal for civil construction, infrastructure, mining and quarrying projects of any size. From road surveying to topography mapping, volume calculations and cut/fill mapping, Virtual Surveyor gives you the tools to quickly and accurately track and optimise your project as it takes shape.

  • Topographic surveys
  • Mining & quarrying
  • Construction earthworks
  • Stockpile inventory

Combine the power of your brain to interpret complex topographies with the calculation power of the computer to create drone surveys in very short times.
Use drone data for a more efficient and safer mine management. Create more accurate reports on excavations and stocks. Bridge the gap with your specialized mining software.

Keep track of your construction project with multiple drone surveys. Compare with your baseline or design surface and determine how much work needs to be done.

Quantity surveyors generate complex reference surfaces to assess stocks in an accurate and repetitive way.

A survey with a drone adds additional complexity to your workflow. It is important to understand where you are as a surveyor in the entire workflow.
Flying. The Drone Operator flies with a drone and acquires a set of pictures of the project site.
 The Photogrammetrist creates an orthophoto and elevation model from the pictures.
Virtual Surveying.
 The Surveyor creates a line survey, triangulation or contours in Virtual Surveyor.
Civil Design
. The Civil Designer uses the survey outputs to create a civil design in a CAD design software.


Creating a topographic survey with a drone is a completely different process compared to a terrestrial survey with the boots on the ground.

A topographic surveyor models the outside world by measuring as few points and lines as possible, while surveying with a drone requires flightplanning, piloting, an entire logistic operation and photogrammetry.

Another big challenge is that the orthophotos, elevation models and point clouds coming out from the photogrammetry process differ completely from what the engineers expect the surveyor to deliver. Civil or mine engineers want a lightweight but meaningful CAD model that they can load directly in their CAD design software packages.

The Kardia mine in West Macedonia saves big bucks with more accurate volume measurements using drone surveying. The surveying team operates the following workflow on a monthly basis:
  • Flight planning with eMotion software.
  • Drone flight with the eBee RTK from SenseFly.
  • Photogrammetry with Pix4Dmapper software.
  • Removal of conveyors, measurement of volumes and drawing of breaklines with Virtual Surveyor software.
  • Constructing future excavations with Anadelta Tessera software.

Survey points and break lines

Draw points, point grids, lines and polygons in a realistic virtual environment. Save on the field work, save time and work from the comfort of your office with the ability to analyse the environment at different angles.

Create and import surfaces

Create a triangulation from your survey and verify instantly with with your terrain. Improve the model by adding points or break lines and triangulate again, giving you an accurate survey that truly represents the topography.

Quickly add section lines to road surveys

Simply create a centre line for the road, then add and densify section lines to create road surfaces quickly and accurately, modelled on the existing topography.

Matrice 350 RTK

An upgraded flagship drone platform, the Matrice 350 RTK sets a new benchmark for the industry. This next-generation drone platform features an all-new video transmission system and control experience, a more efficient battery system, and more comprehensive safety features, as well as robust payload and expansion capabilities. It is fully powered to inject innovative strength into any aerial operation.

GPR system: Radar Systems Zond Aero LF (low frequency)

Extra-lightweight GPR system, suitable for medium-sized drones like DJI M300 RTK.

Comes with 3x sets of dipoles for the 300, 150, and 100 MHz.

Utilizes Real Time Sampling (RTS) with high hardware stacking, delivering high-resolution low-noise data.

Laser Falcon methane detector

Laser Falcon is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.

The concept is based on Infrared Absorption Spectroscopy. The laser emits light (spectral range of 1,65 μm), which reflects back and is captured by the sensor. The outgoing and incoming signals are compared with the built-in reference cell. If methane is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.
