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.
