Towards Systematic Selection of Terrain- and Ground Cover-Specific LiDAR Filtering Parameters
… of multiple bare-earth classifications in LAStools using a range of parameter combinations and compares each to a small but representative manually-classified control surface. From these automated comparisons, the best performing parameters can be rapidly determined and subsequently applied …

Evaluating the quality of ground surfaces generated from Terrestrial Laser Scanning (TLS) data
… Four popular ground filter tools (ArcGIS, LASTools, PDAL, MCC) were applied to both ALS and TLS data. The output ground point clouds were then compared with a DTM generated from ALS data of the same region. Among the four ground filter tools employed in this research, the distances from TLS …

Use of Lidar Data to Investigate the Influence of Bottom Friction Coefficients for Storm Surge Modeling of Hurricane Michael in the Florida Panhandle
… District, were processed using ArcGIS, Python, LAStools, and a random forest model to calculate spatially variable Manning’s roughness coefficients (<em>n</em>). This is the first time the process has been applied at the multi-county scale. Using the numerical hydrodynamic modeling code ADCIRC, …
