10 Reason of Using Terrestrial Laser Scanning (TLS) in Surveying
Why Terrestrial Laser Scanning (TLS) is Essential in Surveying
Terrestrial Laser Scanning (TLS) is also known of Terrestrial LiDAR. The term LiDAR is Light Detection and Ranging basically consist of laser rangefinder that operates in some form of platform such as a tripod, or any other vehicle.The rangefinder takes repeated measurements of the distances from the platform to the surfaces or structural. The position and the elevation of the platform is precisely known by the way of survey method and dimensional control points.
So, the coordinate of the surfaces can be calculated by subtracting laser rangefinder distance from the platform location.
Laser scanning with its high level of accuracy and high level of detail is very versatile and has been utilized. Here are 10 reasons for using terrestrial Laser Scanning in surveying.
1. TLS provides high precision and accuracy as compared to traditional surveying methods.
Rapid collection TLS Technologies is a laser beam accuracy that’s allowing for highly accurate 3D models to be created.
Additionally, TLS measurements are not subject to the same human error as traditional surveying methods, such as errors in observing using total station or dumpy leveling.
Additionally, TLS measurements are not subject to the same human error as traditional surveying methods, such as errors in observing using total station or dumpy leveling.
This results in higher precision and accuracy in mapping, making TLS an increasingly popular tool in fields such as architecture, engineering, construction, and land surveying.
This results in a large amount of data being collected in a short amount of time. In fact, a single TLS scan can capture millions of points in just a few minutes, which is significantly faster than traditional surveying methods.
This quick data acquisition allows for more efficient mapping and can save time and resources in the field. structures. Laser scanning is a very efficient survey method to reduce costs.
This level of detail allows for highly accurate 3D models to be created, which can be used for a variety of applications, such as design, analysis, and visualization.
The high level of detail also makes TLS a useful tool in fields such as archaeology and cultural heritage, where precise measurements are essential for documenting and preserving historical sites and artifacts.
TLS is an observational technology, which means that mapping can be carried out without physically disturbing the site. This is particularly useful in sensitive areas or where site access is difficult.
Traditional surveying methods, such as total station surveys, often require physical access to the site, which can cause damage to sensitive areas or disrupt ongoing operations. With TLS, the scanner can be set up at a distance from the site and can capture data without the need for physical access.
This can be useful for city planning, maintenance, and renovation projects. In rural landscapes, TLS can be used to create detailed maps of topography, vegetation, and soil erosion.
This can be useful for environmental monitoring, land use planning, and natural resource management. In archaeological sites, TLS can be used to create accurate 3D models of artifacts, structures, and landscapes.
This can be useful for documentation, research, and preservation purposes.
In contrast, TLS can capture millions of points per second and produce accurate 3D models with high resolution in a matter of hours or days, depending on the size of the site. This significantly reduces the need for personnel and speeds up the surveying process.
Additionally, TLS can reduce the need for revisits to the site, as it captures a comprehensive data set that can be revisited and reanalyzed in the future. This reduces the costs associated with repeated site visits and measurements.
These models can be used for a variety of purposes, such as urban planning, architecture, and cultural heritage preservation. Moreover, TLS data can be used to create virtual reality (VR) experiences, which can provide an immersive and interactive way of exploring the site.
VR experiences can be particularly useful for cultural herit age sites, where visitors may not be able to access certain areas or artifacts. By creating a VR experience, visitors can explore the site in detail and learn about its history and significance.
Additionally, 3D models and VR experiences can be used to communicate complex information to stakeholders, such as engineers, architects, or government officials.
These visualization tools can provide a clear and intuitive way of presenting information, which can facilitate decision-making and stakeholder engagement.
In contrast, TLS can capture detailed data from a distance, without the need for surveyors to physically access the area, reducing the risks associated with working in hazardous environments.
