Get the Coordinate Reference System (CRS) of LASfiles

Source: R/get_crs.R
get_crs.Rd

get_crs() efficiently extracts and returns the coordinate reference system (EPSG code) of LASfiles.

Usage

get_crs(path, full.names = FALSE)

Arguments

path

Character. Path to a LAS/LAZ/COPC file, a directory containing LASfiles, or a Virtual Point Cloud (.vpc) referencing LASfiles.

full.names

Logical. If TRUE, the returned filenames will be full paths; if FALSE (default), only base filenames are used.

Value

A data.frame with two columns:

filename

The filename or full path of each LASfile.

crs

The EPSG code of the file's coordinate reference system.

Details

This function efficiently reads the Coordinate Reference System of LASfiles from VPC. It is suitable for quickly inspecting the CRS of multiple LAS/LAZ/COPC files.

Examples

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

las_files |> get_crs()
#> Error in loadNamespace(x): there is no package called ‘lasR’
