LiDAR analysis and reporting of 11,000 miles of fiber and electric networks in the United States.

In response to the increasing demand for line surveys for fiber installation, Dielmo 3D has created methodologies that allow accurate results to be obtained from LiDAR data.

Here, we explain it in detail presenting one of the multiple projects carried out from LiDAR data -over 2 years long- using this new methodology, with which there are already more than 11,000 miles surveyed. Keep reading about this project!

The objective of the project

This project aims to study and analyze existing power networks, both transmission and distribution lines. Its purpose: to detect risk areas where the installation of possible new fiber optic lines (on these structures) could produce a safety risk or a non-compliance with current regulations.

For this purpose, Dielmo 3D developed its own 100% automated methodology. This system allows the detection of the potential risk, the identification of the risk typology, the measurement and reporting of safety distances -for all the elements of the network-, such as: the inclination of poles, the lowest point of the span, the distance between telecom and power cables, etc.

The meaning of the project

To understand the project, one question must be asked: why is it requested? It was born out of a clear need: to extend the Fiber Optic network throughout the territory, and in the fastest and most efficient way possible. To achieve this, in many cases the reuse of existing infrastructures is proposed, incorporating a new FIBRA/Telecom line to the network.

Usually, in this type of projects, Dielmo 3D offers its clients one or both of the following products:

  • A detailed study of the network and the loads it could support (performing PLS-CADD modeling).

  • Verification that the installation on existing fiber lines complies with national NESC safety parameters.

This requires launching measurements from multiple key elements of the network. In this way, it can be confirmed that the current network complies with current regulations.

In the case of non-compliance, centimeter-accurate detection, measurement, classification and reporting would be required.

The actions carried out

  • Acquisition of LiDAR data.

  • The identification and classification of all the elements of study, from the electrical wiring by voltages, to existing electrical elements in each pole or span (transformers, risers, guy wires, etc.).

  • The development of algorithms for each study element detected, as well as clearance measurements, simple and combined, to confirm if each span and structure meets or does not meet the requirements, with automatic reports, classified according to risk, type of element and distance detected.

So that the data can be exploited in different areas, the results obtained are generated in different formats, according to your needs:

  • In a complete Excel report, containing all the coordinates, distances, codes and references necessary to identify and evaluate the risk.

  • In a PLSCADD file, with all the study performed and the simulation, complying with the regulations of the new fiber line in the existing network.
