We specialise in providing topographical site surveys, terrestrial laser scanning and airborne LiDAR services. Working in land surveying for nearly 40 years and in countries all over the World across a wide variety of industry sectors we look forward to your enquiry.
To help describe our range of services we have created specialist websites for our specialisations including, pipeline survey, mining surveys, storage tank surveys, airborne lidar, complex plant and all aspects of laser scanning and 3D modelling. We opened an office in Cameroon to help promote our African experience. Please refer to ‘Africa Precision’.
What is topographical surveying? Topography is the study of the shape and features of land surfaces, and so, of course, the measurement of that land and features upon it plus its representation on a plan or map is the survey. But nowadays the work of a land surveyor is so much more than that. The methods of measurement are changing so rapidly as new technologies are applied to the task – remote sensing from satellites, aircraft and drones using imagery, lidar and radar have advanced the speed and accuracy of data capture. On the ground (and indeed under it), the topographical survey data is measured using GNSS (GPS), laser scanning, GPR – ground penetrating radar, mobile laser scanning, remotely operated vehicles and robotic survey instruments.
Then the processing and presentation of the data can be so much more than simple topographical 2D plans, elevations and sections with the use of 3D modelling and VR and AR. Virtual Reality and Augmented Reality.
The Knowledge Centre on this website will introduce to a more expanded view of topographical survey, land survey and measured building surveys and how they are all part of the ever expanding field of Geomatics and Geospatial services.
Merretts provided an excellent service when called upon. They were responsive, helpful, innovative and effective and worked well as part of the overall team delivering emergency response to the South West of England.
Merretts have shown themselves to be technically very capable, providing a positive professional approach.
Their deep understanding of GPS & rigid quality controls has particularly impressed us.
