Edit an attribute of the points — edit

Edit an attribute of the points by filtering the point based on criteria.

Usage

edit_attribute(filter = "", attribute = "", value = 0)

Arguments

filter: the 'filter' argument allows filtering of the point-cloud to work with points of interest. For a given stage when a filter is applied, only the points that meet the criteria are processed. The most common strings are Classification == 2", "Z > 2", "Intensity < 100". For more details see filters.
attribute: string. The name of an attribute to edit
value: numeric. The value to assign. Be careful, if the user try to assign a value out of range of representable value for a given data type it will be clamped.

Value

This stage transforms the point cloud in the pipeline. It consequently returns nothing.

Examples

f <- system.file("extdata", "Example.las", package="lasR")

edit = edit_attribute(filter = c("Z < 975", "Z > 974"), attribute = "UserData", value = 2)
io = write_las(templas())
pipeline = edit + io
ans = exec(pipeline, on = f)
