Drone LiDAR Survey with combination of Drone Photogrammetry Data

UAV/UAS LIDAR Survey

Land Surveying and related services using Drone LiDAR

UAV/UAS LiDAR is installed on a drone for collecting data. It's is performed looking down on the ground. As soon as it’s activated, LiDAR emits light towards the ground surface, which returns to the sensor immediately after hitting the object, giving an exact measurement of its distance.

Drone survey covers larger portions of the terrain and are not limited to ground navigable terrain. It's point density is almost uniform and drone LiDARs have more flexibility of where they can collect data. It had the best rating for post-processing efficiency.

UAV LiDAR as an active sensor technology penetrates vegetation. LiDAR is able to get through gaps in the canopy and reach the terrain and objects below, so it is useful for generating Digital Terrain Models. LiDAR is also particularly useful for modelling narrow objects such as power lines or telecom towers. LiDAR sensor is coupled with IMU (inertial motion unit) and GNSS receiver, which provide information about the position, rotation, and motion of the scanning platform. It allows achieving high relative accuracy (1-3cm). High absolute accuracy requires adding 1-2 Ground Control Points (GCPs) and several checkpoints

FAQ

1) What is LiDAR?

2) What is LiDAR Survey?

Lidar means “light detection and ranging.” It is sometimes called “laser scanning” or “3D scanning.” A typical lidar sensor emits pulsed light waves. These pulses bounce off surrounding objects and return to the sensor. The sensor uses the time it took for each pulse to return to the sensor to calculate the distance it traveled. Repeating this process millions of times per second creates a real-time 3D map.

LiDAR Scanner uses the pulse from a laser to collect measurements to create 3D models and maps of objects above the surface. The system calculates how long it takes for beams of light to hit an object or surface and reflect back to the laser scanner. The distance is then calculated using the velocity of light. LiDAR scanning units can fire million of pulses per second. Each of these pulsed laser measurements, or returns, can be processed into a 3D visualisation known as a ‘point cloud.’

3) What is Point Cloud?

A point cloud is made up of millions of points within the scans captured by a 3D laser scanner. These points represent a point on the surface of, for instance, a scanned building. The scanner automatically combines the vertical and horizontal angles created by the laser beam to calculate a 3D XYZ coordinate position for each point to produce a set of 3D coordinate measurements.

The point cloud data can then be transformed into a digital 3D model that gives you an accurate detailed picture of AOI (Area of Interest). The denser the points, the more detailed the representation, which allows smaller features and texture details to be more clearly and accurately defined.

4) What are benefits of LiDAR Surveying?

1) Fast method of surveying
2) Collects Extremely Dense Data
3) Results are highly accurate
4) Can be mounted on to Cars, Trains, Boats or Drones
5) LiDAR systems work relatively safety and can be operated remotely

Mobile lidar scans very close to ground. So, it is prefered for Highway and railway survey. Drone lidar can be operated over hazardous and inaccessible area, i.e., forests and mashy lands. So, it is prefered for Green Field Alignments, bypasses and re-alignments.

5) How much is it cost for lidar survey?

Where the places you work?

Based on the scope of work, required accuracy , size of the project, location of the project and list of deliverable, we quote between Rs.1,000/- to Rs.12,000/- per acre. For linear projects kindly send us the Area of Interest (kml) and survey specifications. We shall send a free quotation.

Goodland works in all over India include Andaman Nichobar Islands for surveying and mapping. We also worked in Addu (Maldives), Gabon (Africa), Brisbane (Australia) and Gulf countries. We takes LiDAR data post processing from many countires.
