Check whether LASfiles are spatially indexed — is

is_indexed() whether LASfiles are spatially indexed (either via external .lax file or internally)

Usage

is_indexed(path, full.names = FALSE)

Arguments

path: Character. Path(s) to a LAS/LAZ/COPC file, a directory containing such files, or a Virtual Point Cloud (.vpc).
full.names: Logical. If TRUE, return full file paths; otherwise return base filenames only (default).

Value

A data.frame with columns:

file: Filename of the LASfile.
is_indexed: Logical indicating whether point cloud is spatially indexed

Details

The input may be a single file, a directory containing LASfiles, or a Virtual Point Cloud (.vpc) referencing LAS/LAZ/COPC files. Internally, file paths are resolved using resolve_las_paths().

Examples

folder <- system.file("extdata", package = "managelidar")
las_files <- list.files(folder, full.names = T, pattern = "*20240327.laz")
