What is LIDAR?

 Light Detection and Ranging

LIDAR surveying (Light Detection and Ranging) is a technology that uses lasers to measure distance to objects or surfaces. Typically, LIDAR sensors mount on platforms such as drones or cars. These sensors emit lasers that bounce off objects and return to the sensor. By measuring the time it takes for the lasers to return, the sensor calculates the distance. As a result, it creates a detailed 3D map of the surrounding area.

LIDAR serves various applications, including mapping, surveying, self-driving cars, and robotics. In particular, it excels where high accuracy and precision matter. This is because LIDAR sensors capture detailed 3D data with millimetre-level accuracy.

Often, LIDAR works alongside other sensors, such as cameras and radar, to provide a more comprehensive view. Additionally, it supplements GPS data, which can suffer errors in some environments.

What is Lidar Surveying?

LIDAR surveying uses LIDAR technology to measure distance and create detailed 3D maps of the surrounding area. The sensors emit lasers that bounce off objects and return to the sensor. By measuring the laser’s return time, the sensor calculates the distance accurately.

LIDAR surveying finds applications in many fields, including mapping, geology, construction, and transportation. It works especially well where high accuracy and precision are required. LIDAR sensors capture detailed 3D data with millimetre-level accuracy, making them ideal for such tasks.

Often, LIDAR surveying combines with other sensors like cameras and radar to provide a fuller view of the environment. Additionally, it supplements GPS data, which can sometimes be inaccurate in certain conditions.

You can perform LIDAR surveying using various platforms, such as drones, cars, boats, and airplanes. This method captures detailed 3D data quickly and efficiently over large or hard-to-reach areas.

How Does Lidar Surveying Work?

Lidar (Light Detection and Ranging) surveying accurately measures distance by emitting a laser pulse and timing its return. The sensor calculates distance using the speed of light and the pulse’s travel time. Typically, a lidar sensor mounts on a vehicle or aircraft for detailed earth surface mapping. The sensor emits laser pulses and measures the time they take to bounce back from the ground, buildings, and objects. Then, it uses this data to create a precise 3D map of the surveyed area.

Lidar surveying offers accurate and efficient data collection. Consequently, it suits many applications, including topographic mapping, engineering, and geospatial analysis.

LIDAR Drone

A LIDAR drone is any aerial drone with a LIDAR sensor attached.

In recent years, innovation in LIDAR technology has dramatically lowered both the cost and size of LIDAR sensors, making it more feasible to attach a LIDAR payload to a drone. And as LIDAR drones become more common, the information they can provide is far more accurate and far less expensive
