Laser Scanning Sydney

The technique of laser scanning, also known as high-definition surveys, captures three-dimensional information that reflects from a surface or object to a light sensor.

A ‘point cloud’ is a 3D construct made from multiple scans that have been unified by a process of registration.
 
A point cloud can be consolidated into traditional deliverables, including 2D plans, elevations, and sections. A BIM model, fly-through, and point cloud are used for context.

Comprehensive Scanning

You should look for a land surveyor who offers 3D laser scanning if you want the most comprehensive services possible. Laser scanning, also known as LIDAR (light detection and ranging) in the surveying world, uses laser technology to scan a geographic area. Lasers, whether they are pointed at a building, a tree, or the ground, reflect light back to a light sensor, which records it as a data point. In order to deliver detailed survey deliverables, we can combine the points into what is known as a ‘point cloud.’

How 3D Laser Scanning Can Assist You

In so many cases, 3D laser scanning surveys are the ideal kind of land surveying. Several surveying problems can be solved using a well-executed LIDAR 3D survey:

  • Slow surveying processes. The old on-the-ground surveying methods took a long time and proved to be time-consuming. LIDAR is especially helpful when clients cannot wait so long for survey results. Automated point clouds are generated through the laser scanning process, which is relatively quick.
  • Access limitations for survey properties. The land and properties surveyed by surveyors cannot always be accessed. It can be difficult for surveyors to enter areas with rough or impassable terrain, or those that are contaminated or otherwise dangerous. Busy roads or areas with high traffic can also pose problems. Without having to conduct a ground survey, laser scanning is able to map these areas.
  • Site revisits. It is also common for conventional surveying techniques to miss or incorrectly collect data, which makes site revisits inevitable. A project’s cost and timeline can be affected by these additional site visits. As a result of using laser scanning to collect information from a site, even the most complex information is rarely missed or inaccurate data is collected. In this sense, it is alternatively known as high-definition surveying (HDS).
