Process the pipeline. Every other functions of the package do nothing. This function must be called on a pipeline in order to actually process the point-cloud. To process in parallel using multiple cores, refer to the multithreading page.
Arguments
- pipeline
a pipeline. A serie of stages called in order
- on
Can be the paths of the files to use, the path of the folder in which the files are stored, the path to a virtual point cloud file or a
data.framecontaining the point cloud. It supports also aLAScatalogor aLASobjects fromlidR.- with
list. A list of options to control how the pipeline is executed. This includes options to control parallel processing, progress bar display, tile buffering and so on. See set_exec_options for more details on the available options.
- ...
The processing options can be explicitly named and passed outside the
withargument. See set_exec_options

tri <- triangulate(15)
dtm <- rasterize(5, tri)
lmf <- local_maximum(5)
met <- rasterize(2, "imean")
pipeline <- read + tri + dtm + lmf + met
ans <- exec(pipeline, on = f, with = list(progress = TRUE))
