Surveying is described as the technique and science of accurately determining the terrestrial or three-dimensional position of points and the distances and angles between them. In particular, there is land surveying which focuses on the detailed study and data gathering which can provide engineers with land mapping, construction layout surveys and elevation analysis.
The most common equipment used for surveying is a theodolite. Starting from a position with a known location and elevation, the distance and angles to the unknown point can be measured. It is a very dependable yet slow process to gather many points.
With the revolution of laser scanning, many surveyors are looking to faster and more comprehensive tooling such as laser scanning. With the release of the new Laser Scanner Focus3D, users are able to capture exceptional quality point clouds of large areas within minutes. At a full resolution scan, the Focus3D is capable of scanning up to 976,000 million points per second. That is much more data than a standard theodolite.
One company is Europe is using the FARO Laser Scanner in common surveying applications. From these point cloud data sets, engineers can create 3D models, measure distances, generate 2D CAD plan views and map assets for clearance.
