What is LIDAR?

 Light Detection and Ranging

LIDAR surveying (Light Detection and Ranging) is a technology that uses lasers to measure the distance to an object or surface. LIDAR sensors are mounted on a platform, such as a drone or a car, and emit lasers that bounce off objects and return to the sensor. By measuring the time it takes for the lasers to return, the sensor can calculate the distance to the object and create a detailed 3D map of the surrounding area.

LIDAR is used in a variety of applications, including mapping, surveying, self-driving cars, and robotics. It is especially useful for applications that require high accuracy and precision, as LIDAR sensors can capture detailed 3D data with millimetre-level accuracy.

LIDAR is often used in conjunction with other sensors, such as cameras and radar, to provide a more comprehensive view of the surrounding environment. It is also used to supplement GPS data, which can be prone to errors in certain environments.

LIDAR surveying can be performed using a variety of platforms, including drones, cars, boats, and aeroplanes. It is a quick and efficient way to capture detailed 3D data of large areas or hard-to-reach locations.

How Does Lidar Surveying Work?

Lidar (Light Detection and Ranging) surveying is a method used to accurately measure the distance to a target by emitting a laser pulse and measuring the time it takes for the pulse to return after it is reflected off the target. The distance to the target can then be calculated using the speed of light, and the time it took for the pulse to return. Lidar surveying is typically conducted using a lidar sensor, which is mounted on a vehicle or an aircraft and can be used to map the surface of the earth in great detail. The sensor emits laser pulses and measures the time it takes for the pulses to bounce back from the ground, buildings, and other objects. This information is then used to create a 3D map of the area being surveyed.

Lidar surveying is a very accurate and efficient method for collecting data, and it can be used for a variety of 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
