Ministry for the Environment, Land Use Carbon Analysis System collection of swaths of LiDAR over planted forests of interest (raw and classified returns) from 2006 to 2015.
LiDAR swaths were captured with Optech sensors as part of a plot-based forest inventory system developed for pre-1990 planted forests. Plot sites cover a circular area with a radius of 85m (0.06 ha). LiDAR data and aerial photography typically was collected between plots where the inter-site area was also planted forest.
Typically Precise Point Positioning (PPP) algorithms were used to improve the POS GPS/IMU locating data.
DTM point cloud classification was undertaken using editing software such as TerraSolid TerraScan.
