3D Terrestrial Laser Scanning

Vision’s services in spatial data 

Vision Surveys (QLD) offers terrestrial laser scanning (TLS) across Australia, utilising a variety of laser scanning services and technologies to capture detailed and accurate 3D data of built and natural environments. We provide precise spatial information for various applications, including land development, construction, infrastructure, resource and energy infrastructure and defence projects.  

Our 3D terrestrial laser scanning technology 

With fleet standalone scan stations, scanning total stations and Simultaneous Localisation and Mapping (SLAM) based platforms, Vision Surveys (QLD) is equipped to select the most suitable platform for collecting project specific data. Whether our client needs millimetre accuracy on individual structural components, or an entire hospital or refinery captured for upgrading, Vision Surveys (QLD) has the right sensors to gather necessary information with the desired accuracy, maximising efficiency and cost effectiveness.

Capturing safe and accurate data with terrestrial laser scanning

Terrestrial laser scanning sits within our remote sensing technologies and allows our surveyors to capture survey data from a distance, eliminating the need to operate in hazardous environments such as road corridors, industrial plants or active quarries. This approach ensures safety and efficiency while providing comprehensive data compared to traditional methods.  

Vision Surveys (QLD) is also experienced and skilled in translating raw survey data into concise deliverables, from accurate Building Information Modelling (BIMs) to conventional CAD topographic survey.

3D terrestrial laser scanning FAQs

What is terrestrial laser scanning (TLS)?  

Terrestrial laser scanning is a surveying technology that uses a laser scanner to capture highly accurate 3D data of objects or environments. It's commonly used in architecture for site analysis, as-built documentation and design processes.  

How does terrestrial laser scanning work? 

Terrestrial laser scanning works by emitting laser pulses towards objects or surfaces and measuring the time it takes for the laser to bounce back. This information is used to calculate the distance to the object and create a point cloud representing the 3D geometry.  

What are the main benefits of using terrestrial laser scanning in architecture? 

Terrestrial laser scanning provides highly detailed and accurate 3D data quickly, allowing architects to create precise as-built documentation, assess site conditions, and streamline design processes. It also minimises the need for manual measurements, reducing errors and saving time. 

What types of projects benefit from terrestrial laser scanning technology?  

Terrestrial laser scanning is valuable for a wide range of architectural projects, including building renovations, historic preservation, site analysis, construction quality control, and large-scale urban planning. 

When should high-accuracy terrestrial laser scanning (TLS) survey techniques for whole of facility projects?  

 High-accuracy terrestrial laser scanning is ideal when precise and detailed data is critical for master planning, feasibility design, and detailed design phases. It excels in capturing intricate architectural details, structural elements, and spatial relationships within complex facilities such as shopping centres, hospitals, and refineries.
