Get the spatial extent of LASfiles (individuially or combined)

Source: R/get_spatial_extent.R
get_spatial_extent.Rd

get_spatial_extent() extracts the spatial extent (xmin, xmax, ymin, ymax) from LASfiles. Can return extent per file or the combined extent of all files.

Usage

get_spatial_extent(
  path,
  per_file = TRUE,
  full.names = FALSE,
  as_sf = FALSE,
  verbose = TRUE
)

Arguments

path

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

per_file

Logical. If TRUE (default), returns extent per file. If FALSE, returns combined extent of all files.

full.names

Logical. If TRUE, filenames in the output are full paths; otherwise base filenames (default). Only used when per_file = TRUE.

as_sf

Logical. If TRUE, returns an sf object with geometry. If FALSE (default), returns a data.frame.

verbose

Logical. If TRUE (default), prints extent information.

Value

When per_file = TRUE: A data.frame or sf object with columns:

filename

Filename of the LASfile.

xmin

Minimum X coordinate.

xmax

Maximum X coordinate.

ymin

Minimum Y coordinate.

ymax

Maximum Y coordinate.

geometry

(optional) Polygon geometry if as_sf = TRUE.

When per_file = FALSE: A single-row data.frame or sf object with the combined extent.
