3D LiDAR surveying 

When you are looking to save time and require accuracy, 3D LiDAR surveying is the way to go. That’s why more and more companies are turning to us to capture their data. When it comes to LiDAR, speed and precision are the biggest benefits. LiDAR surveys deliver fast precise and consistent outputs. LiDAR excels at detecting objects of any size and generating highly precise 3D models. 

What is the difference between LiDAR and traditional land surveys?  

LiDAR surpasses traditional surveying methods in terms of speed and accuracy. Unlike conventional approaches, LiDAR surveys remain unaffected by adverse weather conditions, making it an optimal choice for many projects. It can operate in temperatures from –40 to +40 degrees.  However, it is worth noting that LiDAR does not perform well in heavy snow or rain. 

What are the benefits of using LiDAR to survey an area? 

Accuracy is a significant advantage of using LiDAR for surveying purposes. LiDAR collects densely packed data points, resulting in highly accurate scans. The precision of the outputs makes it easier to plot, model and measure. Resulting in perfect planning, insights and spot on projects. 

What are the types of LiDAR? 

Airborne LiDAR:

Airborne LiDAR is installed on aircraft, helicopters, or drones. Airborne LiDAR emits light toward the ground surface, enabling precise distance measurements. 

Bathymetric LiDAR:

Bathymetric LiDAR measures water body depths. By using a green wavelength capable of penetrating water, it excels in surveying rivers, lakes, and seas. 

Topographic LiDAR:

Topographic LiDAR uses a red laser to map land surfaces. It measures and creates detailed illustrations of the Earth’s topography. Topographic LiDAR data provides detailed information about the shape, contour, and elevation of land surface. It is extremely useful for gathering crucial data in urban planning, civil engineering, environmental monitoring, and natural resource management. 

Terrestrial LiDAR Scanning (TLS):

Terrestrial LiDAR Scanning, also known as TLS, involves stationary systems that scan areas from fixed points. It is renowned for its shorter range and superior accuracy, compared to airborne or mobile LiDAR. TLS is an ideal choice for detailed surveys of buildings, structures, objects, and archaeological sites. 

What does lidar mean in construction? 

LiDAR, helps construction practices by using safe laser beams. These quickly generate precise 3D representations of environments and objects, giving builders, and architects invaluable insights. 

What is the use of lidar in BIM? 

LiDAR data is an superb geospatial data collector, which is a vital requirement for accurate BIM software modeling and tracking. Because of LiDAR’s exceptional accuracy, it enables the creation of precise digital models. LiDAR processed models reproduce a building’s physical characteristics, its geometry, and spatial relationships. 

How accurate is a terrestrial (TSL) LiDAR survey? 

LiDAR sensors achieve a  mapping accuracy of up to 1cm horizontally and 2cm vertically, LiDAR is an excellent tool for accurate mapping. We primarily use Riegl scanners, depending on the project requirements and outputs we also use Leica, Geo slams, or Artec. 

How accurate is a liDAR drone survey? 

On average, a lightweight LiDAR system mounted on a fixed-wing drone offers an accuracy of about 10 cm horizontally and 5 cm vertically.
