add_images: Add images to an existing image collection

In gdalcubes: Earth Observation Data Cubes from Satellite Image Collections

Add images to an existing image collection

Description

This function adds provided files or GDAL dataset identifiers and to an existing image collection by extracting datetime, image identifiers, and band information according to the collection's format.

Usage

add_images(
  image_collection,
  files,
  unroll_archives = TRUE,
  out_file = "",
  quiet = FALSE
)

Arguments

image_collection	image_collection object or path to an existing collection file
files	character vector with paths to image files on disk or any GDAL dataset identifiers (including virtual file systems and higher level drivers or GDAL subdatasets)
unroll_archives	automatically convert .zip, .tar archives and .gz compressed files to GDAL virtual file system dataset identifiers (e.g. by prepending /vsizip/) and add contained files to the list of considered files
out_file	path to output file, an empty string (the default) will update the collection in-place, whereas images will be added to a new copy of the image collection at the given location otherwise.
quiet	logical; if TRUE, do not print resulting image collection if return value is not assigned to a variable

Value

image collection proxy object, which can be used to create a data cube using raster_cube

Examples

L8_files <- list.files(system.file("L8NY18", package = "gdalcubes"),
                         ".TIF", recursive = TRUE, full.names = TRUE)
L8_col = create_image_collection(L8_files[1:12], "L8_L1TP") 
add_images(L8_col, L8_files[13:24])
