We make inventories of overhead power lines using airborne laser scanning. This makes measurement and processing a rapid process, while maintaining the required accuracy.

We precisely measure thousands of points on the wires and then process the data using specialized software.

During the flight, we also acquire detailed information about the terrain around the lines.

LIDAR scanning makes it possible to acquire data around a power line in a fast way.

Aerial techniques work well in areas with difficult access.

A digital terrain model supplemented with orthophotomap and data from the real estate cadastre gives a complete set of spatial data.

Point classification makes it possible to accurately determine the location of wires and poles.

We classify the point cloud obtained during aerial scanning to extract the wires. Specialized software allows us to fit a catenary, making the whole process very precise.

We also determine the exact location of the poles, and vectorize the poles in a schematic way.

On the basis of this data, power line profiles are produced, which are important both for planning line upgrades and for planning network load increases, where information on the distance between the line and the terrain or buildings is crucial.
