High Quality Land and UAV Survey Services

Aerial surveying using UAVs offers rapid data acquisition and provides an efficient, safe solution to areas that are inaccessible using other techniques.

Combining photogrammetry techniques with UAV LiDAR can give enhanced results across a range of applications from surveying a bridge deck to wind turbine inspections, drones make it easy to cover large or difficult to access areas in minutes.

UAV survey data are acquired, processed and presented differently depending upon the project. Gathered data can be supplied in deliverable formats such as orthophoto, DTM, DSM, pointcloud, Revit surface and AutoCAD.

Safe, accurate, efficient

Our in-house staff are experienced surveyors who are professionally trained to and qualified to operate in the UK.

Data collection for an extensive survey that would typically take a team of surveyors several days to perform can be achieved by UAV in a fraction of the time. Combined with the right skill set and software, UAV drone surveys can acquire high-resolution data with sub-centimetre accuracy.

Results can be faster and more cost-effective for Clients where repeat surveys are needed to monitor environmental conditions or provide situational analysis on an ongoing basis.

Range of data formats

Sub-centimetre accuracy

Inaccessible areas

Rapid acquisition

Industry-leading topographic surveys

The surveys we carry out are used for a variety of purposes including design, development, feasibility studies and construction.

Typically, we would deploy the following traditional land surveying equipment:

GNSS RTK
Robotic Total-Stations
Digital levels

Data is downloaded at the end of each day, with progress and coverage checked. On return to our offices the data will be uploaded into our proprietary survey software packages for processing, charting and reporting as specified by our Client.

Using laser scanning, we can offer an alternative to traditional surveying techniques.

It consists of automated, high-speed data capture of complex and often inaccessible environments. There are many possible outputs available from point clouds and basic measurements through to ortho-images, derived 2D/3D drawings, meshing/surfacing or solid modelling.

3D documentation using laser scanning offers significant advantages compared to conventional methods. A laser scanner records approximately 1 million measuring points per second to produce a precise, three-dimensional image of its surroundings. With suitable plug-ins, this image can then be directly imported into a wide range of software applications.
