LiDAR technology: What it is and how it works in the electrical sector

Topography has contributed a lot when carrying out studies on the conditions in which the different power line systems work or could work. The LIDAR technology has meant a revolution for the industry, thanks to the possibilities that it grants at the moment of making mappings, because it delivers great precision and level of details, which translates into more information at a lower corporate cost. At Ignous we explain you about this tool.

 

What is LIDAR?

 

LIDAR (or Light Detection and Ranging) is an optical remote sensing system that uses laser technology and allows to obtain terrain samples or specific topography routes, facilitating the data extraction on exact measurements. This information can be digitized and then managed, analyzed or shared using the ArcGIS platform.

 

Its operation is with an aerial collection system (in Ignous we use RPAS or drones), a laser scanner, a global positioning system (GPS) and a navigation system by inertia (INS), which calculates the header, tilt and rotation of the LIDAR.

 

How does it work?

 

The LIDAR performs the inspection through the use of laser beams, seeking to analyze their reflection in the sensor’s receivers. In this way, the time from when the laser left the system to its return is recorded, thus calculating the distance between the initial point and the target point. Once that information is collected and adding the information obtained with the GPS and INS, the data is obtained in a three-dimensional format or cloud point.

 

What is a cloud point?

 

The amount of data that is obtained with LIDAR, once organized, is known as cloud point data. The initial data corresponds to a large collection of 3D elevation points, together with additional attributes. Then, the specific entities are classified, earth elevations, freeways elevations, buildings and any other that the laser reaches during the overflight.

 

How does it apply in the electrical industry?

 

Thanks to the capacity of our RPAS pilots, the advances of modern drones and the adaptation of these to any terrain, the overflight of electrical transmission areas allows to obtain precise and exact data.

 

On the other hand, the topographic quality of LIDAR technology, when planning new areas for transmission lines, is very useful, because it provides information about any object or element within the studied area, since it’s capable of analyzing sectors with high forest density, facilitating planning for development or maintenance.

 

Other uses with Ignous:

In addition to our services for power lines, we’ve found other uses using the LIDAR technology for other industries. These are:

  • Agriculture and forestry
  • Archeology and cultural heritage
  • Creation of maps
  • Topography in open-pit mining
  • Inspection of works
  • Urban topography
  • Resource management
