Have you ever been curious about how Lidar surveying works? This advanced technology is used to measure the distance between two points by using a laser. It is a powerful tool that can be used to map land, measure elevations, and even map the seabed and riverbeds. But what is the technical process behind it? Lidar surveying works by pointing a laser at a target surface on the ground or underwater. The surface reflects light back to the Lidar equipment and the sensor records the reflected light to measure the distance traveled.
This data is then combined with the position and orientation of the Lidar equipment, which is measured using the GPS receiver and internal measurement systems. This creates a set of three-dimensional spatial coordinates that include latitude, longitude and height, creating a combination of data called a point. Topographic Lidar usually uses a near-infrared laser to map the land, while bathymetric Lidar uses green light that penetrates the water to also measure the elevations of the seabed and riverbeds. We have extensive experience working with Lidar technology and understand how Lidar mapping works and how to use it.
Lidar surveying is an incredibly powerful tool that can be used for a variety of applications. From mapping land to measuring elevations, it is an invaluable tool for surveyors and engineers alike. With its ability to accurately measure distances, it can be used to create detailed maps of any area with ease. The process of Lidar surveying begins with collecting data from a laser scanner. The laser scanner emits pulses of light that are reflected off of objects in its path.
The time it takes for these pulses to return to the scanner is measured, allowing for accurate measurements of distance. This data is then combined with GPS coordinates and other information to create a three-dimensional map of an area. The data collected by Lidar surveying can be used for a variety of purposes. It can be used to create detailed topographical maps, measure elevations, map riverbeds and seabeds, and even detect changes in terrain over time. It can also be used for engineering projects such as road construction or bridge building. Lidar surveying is an incredibly powerful tool that can be used for a variety of applications.
It is accurate, efficient, and cost-effective, making it an invaluable tool for surveyors and engineers alike. With its ability to accurately measure distances, it can be used to create detailed maps of any area with ease.
