Introduction to the model

Banner image for Power Line Classification model

The classification of point cloud datasets to identify distribution wires is useful for identifying vegetation encroachment around power lines. Such workflows are important for preventing fires and power outages and are typically manual, recurring, and labor-intensive.

This model is designed to extract distribution wires at the street level. Its predictions for high-tension transmission wires are less consistent with changes in geography as compared to street-level distribution wires. In the case of high-tension transmission wires, a lower recall value is observed as compared to the value observed for low-lying street wires and poles.

License requirements

To complete this workflow, the following are the license requirements:

  • ArcGIS DesktopArcGIS 3D Analyst extension for ArcGIS Pro

Model details

This model has the following characteristics:

  • Input—Point cloud in LAS dataset file format (.lasd) or as per Classify Point Cloud Using Trained Model tool.
  • Output—Classified point cloud with three classes: distribution wires, poles, and background.
  • Compute—This workflow is compute intensive and a GPU with compute capability of 6.0 and 8 GB dedicated VRAM is recommended.
  • Architecture—This model uses the PointCNN model architecture as implemented in ArcGIS API for Python.
  • Extra attributes—Input point clouds should have at least x, y, and z.
  • Accuracy metrics—For the validation dataset, the F1 score is 0.896915 for distribution wires and 0.642938 for poles.
  • Class mapping—Points predicted as distribution wires are mapped to class code 14, poles are mapped to class code 15, and background is mapped to class code 0.
