文摘
- •
We introduce a spike-free algorithm for generating Lidar-derived pit-free DSM raster.
- •
The algorithm systematically prevents the formation of spikes during the TIN construction.
- •
Our algorithm takes a raw point cloud as input and produces a spike-free TIN and its corresponding raster.
- •
The algorithm considers all relevant returns instead of using only first-returns.
- •
The algorithm significantly improves the accuracy of treetop detection, especially for small trees.
