We specialise in providing topographical 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. To help describe our range of services, we have created individual websites for our specialisations. These include pipeline surveys, mining surveys, storage tank surveys, airborne lidar, laser scanning & BIM modelling. Having carried out topo surveys all over the world and many across both West and East Africa, we decided to open an office in Cameroon, to help promote our African experience. Please refer to ‘Africa Precision’ for our surveying services in Africa.
Our topographical surveys enable us to identify and map the contours on the earth’s surface and slightly below the surface of the ground. As such, topo surveys from established geospatial professionals such as Merrett Survey Limited, provide an accurate and trusted visualisation of the given area before decisions are made on development. Our topographic surveys specialists can apply their expertise in any industry and are adept in many other areas, of which you can find out more about by visiting our services page. We look forward to providing you with more detail on how we can benefit your organisation or be of use in your project, pending your enquiry.
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.
However, 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, Virtual Reality (VR) and Augmented Reality (AR). The Knowledge Centre on this website will introduce our site visitors to a more expanded view of a topographic survey, land survey and a measured building survey – each of which 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.
