After photogrammetric data processing, Agisoft PhotoScan Pro performs a three-dimensional reconstruction of wires and PTL towers using special software.

As a result, you receive the necessary materials for the subsequent evaluation of the HVL condition, the determination of the parameters and characteristics of HVL and tree and shrubbery vegetation in the corridors and within the protection zone:

Photos

aerial photography in JPG format (resolution is 5 cm/pix and higher)

Orthophotos

in KMZ format (plane accuracy is not worse than 15 cm)

Digital Environment Model

in GeoTIFF or KMZ formats (height accuracy is not worse than 15 cm)

Power lines inspection cards

provided in the PTL (XML) format

3D wires’ reconstruction

models are provided in KML format

Besides the report and all data sets, we provide a specialized GIS "Sputnik PTL" with the uploaded survey results. “Sputnik PTL” is a convenient tool for analysis and evaluation of power lines

Parameters for analyzing in “Sputnik PTL”:

  • Corridor wideness within the PTL protection zone;
  • Heights of detached trees, distinguishable on the DEM;
  • Quantity and location of threatening trees within the PTL protection zone;
  • Quantity and location of trees within the PTL protection zone, which height do not exceed permissible level;
  • Area of threatening tree and shrubbery vegetation within the PTL protection zone;
  • Falling zones of detached trees within the PTL protection zone;
  • Characteristics of the wires within the spans: wire deflection sizes, maximum and minimum deflection;
  • Lengths of spans of PTL;
  • Horizontal and vertical distances from the wires of the HVL to the vegetation within the protection zone;
  • Vertical and horizontal alignments of spans of PTL within the guard zone with metric information;
  • Report in the form provided by the customer, with the possibility of exporting it to the XLS format. Report parameters are filled in automatic and manual mode;
  • Metric characteristics referenced to the DEM.

PTL inspection using quadcopter

Possible additional inspection of detached PTL towers with a copter, which makes it possible to detect defects in insulators, defect of towers, and defects in the armature.
