build_raster_header: Builds a raster header for a flat binary file.

In spatial.tools: R Functions for Working with Spatial Data

Description

Builds a raster header for a flat binary file.

Usage

build_raster_header(
  x_filename,
  reference_raster,
  out_nlayers,
  datatype = "FLT8S",
  format = "raster",
  bandorder = "BSQ",
  setMinMax = FALSE,
  additional_header = NULL,
  verbose = FALSE
)

Arguments

x_filename	Character. The filename of the input binary file.
reference_raster	Raster*. A Raster* object containing the header information to be used.
out_nlayers	Numeric. The number of layers in the flat binary file (defaults to nlayers(reference_raster)).
datatype	Character. The dataType of the flat binary file. See ?dataType for available datatypes. Default is 'FLT8S'.
format	Character. The format of the header. See ?hdr for valid entries. Default is 'raster'. CURRENTLY UNSUPPORTED.
bandorder	Character. The bandorder ('BIP','BIL','BSQ') of the file. Default is 'BSQ'.
setMinMax	Logical. Set the min/max for the file (will take longer to execute)? Default=FALSE.
additional_header	Character. Create additional output headers for use with other GIS systems (see hdr). Set to NULL (default) to suppress.
verbose	logical. Enable verbose execution? Default is FALSE.
