Generate DTM from LiDAR Data

Builds a Digital Terrain Model from the ground points with lidR::rasterize_terrain.

Parameter	Type	Required	Description
`in_las_folder`	directory	Yes	Folder containing the input LAS/LAZ tiles.
`out_folder`	directory (output)	Yes	Folder for the output rasters.
`style`	`tin` \| `idw` \| `kriging`	Yes	Interpolation algorithm. The default is `tin`. An invalid value falls back to `tin`.
`processes`	int	No	Requested number of parallel workers (see How all the tools behave).

`style`	lidR algorithm	Tile output	Merged output
`tin`	`tin()`: Delaunay triangulation	`<tile>_TIN_DTM.tif`	`Merged_TIN_DTM.tif`
`idw`	`knnidw()`: k-nearest-neighbour inverse distance weighting	`<tile>_IDW_DTM.tif`	`Merged_IDW_DTM.tif`
`kriging`	`kriging()`: local ordinary kriging with `gstat`	`<tile>_K_DTM.tif`	`Merged_K_DTM.tif`
