Deprecated function replaced by exec and reader_las
Usage
processor(pipeline, ncores = half_cores(), progress = FALSE, ...)
reader(x, filter = "", buffer = 0, ...)
reader_coverage(x, filter = "", buffer = 0, ...)
reader_circles(x, xc, yc, r, filter = "", buffer = 0, ...)
reader_rectangles(x, xmin, ymin, xmax, ymax, filter = "", buffer = 0, ...)Arguments
- pipeline
a LASRpipeline. A serie of algorithms called in order
- ncores
integer. Number of cores to use. Some stages or some steps in some stages are parallelised but overall one file is process at a time.
- progress
boolean. Displays a progress bar.
- ...
passed to other readers
- x
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](https://www.lutraconsulting.co.uk/blog/2023/06/08/virtual-point-clouds/) file or a `data.frame` containing hte point cloud. It supports also a `LAScatalog` or a `LAS` objects from `lidR`.
- filter
the 'filter' argument allows filtering of the point-cloud to work with points of interest. The available filters are those from LASlib and can be found by running filter_usage. For a given stage when a filter is applied, only the points that meet the criteria are processes. The most common strings are "-keep_first", "-keep_class 2", "drop_z_below 2". For more details see filters.
- buffer
numeric. Each file is read with a buffer. The default is 0, which does not mean that the file won't be buffered. It means that the internal routine knows if a buffer is needed and will pick the greatest value between the internal suggestion and this provided value.
- xc, yc, r
numeric. Circle centres and radius or radii.
- xmin, ymin, xmax, ymax
numeric. Coordinates of the rectangles
