Unmanned Aerial Vehicles Used in Aerial High-Voltage Power Line Survey

Сorridor mapping services for high voltage lines by unmanned aerial vehicles Geoscan. The survey technology Geoscan allows you to restore the wires in a photogrammetric way, which makes the process cheaper and faster than laser scanning.

Power Lines Survey

Results:

Orthomosaics

As KMZ file (plan accuracy not worse than 15 cm)

Digital Terrain Models

As TIFF or KMZ file (height accuracy not worse than 15 cm)

3D reconstruction of wires

Models are provided as KML file

Power lines inspection cards

Provided as an XML file.

Besides the report and all data sets a specialized GIS "Sputnik PTL" with uploaded survey results is provided.

“Sputnik PTL” is a convenient tool for power lines analysis and assessment

Our model allows you

• measure slack of the wire and its clearance to earth;
• measure the forestry area;
• find out the vegetation dangerous to wires;
• measure distances with respect to the terrain;
• measure slops, a difference of height, ground distance;
• measure the area on the digital terrain model (DTM) and digital surface model (DSM);
• export the reports as an XML file;
• render the trees impact zones.

Application fields

Prevention of emergency situations (dangerous vegetation, wire slack)

• Monitor trees and shrubs dangerous to wires
• Define the compliance of wire slack
• Model the impact of the tree zones

Scheduled monitoring

• Detect irregularities within exclusion zones of HVL
• Monitor trees and shrubs growth
• Measure wire clearance to earth

Power lines maintenance (maintenance, lines reengineering)

• Plan the forest corridors widening
• Plan ground maintenance
• Plan power lines reengineering

Mapping

• Count the number of trees growing in the exclusion zone
• Measure the height and diameter of the trees of trunks
• Zone trees and shrubs by height
• Value the cut and slash
