LiDAR Point Data
Network Mapping typically captures 6 million points per route-mile of survey. Using the standard Network Mapping operating parameters, this equates to 11 first points and 11 last points per square meter of transmission survey. This point density ensures that sufficient detail of transmission structures is captured. The huge number of hits on wires provides excellent definition of the catenaries as well as modelling the ground, vegetation and other objects in precise detail.
Digital photography is obtained simultaneously with the LiDAR data. This is used in the classification of LiDAR points to ensure that the relevant code clearances are respected in the engineering model.
Network Mapping capture high definition digital photography with a pixel size of around 2 inches. When this is overlain over the LiDAR data a 3D photo-realistic representation of the transmission route is obtained.
