Powerline Design Project

Project Features
- 102km corridor
- 500m corridor width

Project Deliverables
- 25cm colour ortho photo mosaic
- LiDAR point data (better than +/- 20cm vertical accuracy) classified as:
       - Ground
       - Vegetation greater than 2m in height
       - Above ground features excluding vegetation
       - Existing conductors and wires of adjacent transmission lines
       - Existing structures of adjacent transmission lines

Work Required
- Detailed aerial laser survey of the entire route to determine the ground and vegetation, including towers and wires (conductors and earthwires) of adjacent transmission lines within the corridor, provided in separate files
- Ortho-corrected aerial colour photographs of the entire route providing a resolution of 25cm

The objective of the aerial survey work was to obtain digital elevation data containing ground points and vegetation and subsequent processing to enable direct input into PLS Cadd for 3D modelling of the corridor to assist in optimising tower location and transmission line design.
