Large Scale LiDAR Processing for Wellington Region in New Zealand

Using the Sorted Pulse Data software library (SPDLib) was used in collaboration with Landcare Research to process a regional capture of airborne LiDAR by Wellington Regional Council. The SPDLib software was used on a high performance computing (HPC) system to provide a fully automated processing chain. During the project over 2 Tb of LiDAR point clouds was processed to produce a 1 km tiled grid from which the point clouds were classified to identify ground returns, populate the SPD height field and interpolate digital terrain and surfaces models.
