Laser Scan Surveys: Rapid data collection

Since our inception, Spatial Dimensions has been embracing laser scanning, recognising the benefits the technology can offer to our clients.

What is a laser scanner?

A laser scanner is a measuring device that records geometrical information about any object or surface within its field of view. The collected data is a dimensionally correct 3D representation of the scanner’s immediate environment.

Laser scanners work by rapidly rotating a laser beam and recording up to a million angular and distance measurements every second.  They rely on a clear line of sight to the subject so, for most situations, a single scan will not be sufficient.  Multiple scans from various locations are usually required to obtain enough information to provide a complete ‘picture’ of a site.

The data captured by a laser scanner is known as a point cloud and, depending on the site, can contain billions of 3D points.  The point cloud is a very rich data set and can be used to create drawings and construct 3D models for a wide variety of purposes. We also have the capability to apply realistic colour to the point cloud from our panoramic imaging cameras, further enriching the data set and producing a highly realistic visualisation of the site.

Collecting millions of points in a matter of minutes has proven to be pretty handy to surveyors, as well as being highly beneficial to our clients.  Saving time on site and returning to the office with a detailed point cloud reduces the likelihood of costly site revisits and speeds up the turnaround of detailed surveys. Clever stuff.

Benefits of laser scan surveys

  • Rapid site data collection – up to 1,000,000 points per second
  • Accurate information – positional accuracy down to a few millimetres
  • Completeness of data – a high-definition dimensional record of a site
  • Reduce re-visits to restricted locations
  • Add value by capturing additional surrounding information
  • Permanent ‘point-in-time’ archive record for heritage purposes and reinstatement
  • Collaboration and virtual site visits using TruView™

How much do laser scan surveys cost?

Let us know the details of your site including the required survey extents using an OS plan or similar. We will then contact you to discuss the specification of works and the purpose of your laser scan surveys.

For us, it’s all about using a survey method that’s fit for purpose. It’s why businesses, architects, property developers and faculty managers have chosen Spatial Dimensions to measure their houses, shops, offices, factories, schools, leisure facilities, and hospitals. We’d love the opportunity to help you.

If you need a quick, efficient and discreet team on site, you’ve come to the right place. Contact us today.
