GDALDataset-class: Class "GDALDataset"
Usage
putRasterData(dataset, rasterData, band = 1, offset = c(0, 0))
saveDataset(dataset, filename, options=NULL, returnNewObj=FALSE)
copyDataset(dataset, driver, strict = FALSE, options = NULL, fname=NULL)
deleteDataset(dataset)
saveDatasetAs(dataset, filename, driver = NULL, options=NULL)
Arguments
dataset
An object inheriting from class 'GDALDataset'
rasterData
A data array with length(dim(rasterData)) = 2
band
The band number (1-based) to read from
offset
Number of rows and columns from the origin (usually the
upper left corner) to begin reading from
filename
name of file to contain raster data object; will be normalized with normalizePath returnNewObj
until and including 0.5-27, saveDataset returned an invisible copy of the new file handle, which was then only finalized when the garbage collector ran. The old behaviour can be retained by setting to FALSE, the default behaviour is to close the hande and not return it.
driver
GDAL driver name to use for saving raster data object
strict
TRUE if the copy must be strictly equivalent, or more normally FALSE indicating that the copy may adapt as needed for the output format
options
Driver specific options (currently passed to GDAL)
fname
default NULL, used internally to pass through a file name with a required extension (RST driver has this problem)
Objects from the Class
Objects can be created by calls of the form new("GDALDataset", filename, handle), where name: a string giving the name of a GDAL driver, handle: used internally; not for public consumption (default = NULL).Slots
handle:- Object of class
"externalptr", from class "GDALReadOnlyDataset", used internally; not for public consumption
Extends
Class "GDALReadOnlyDataset", directly.

Details
putRasterData:- writes data contained in
rasterData to the dataset, begining at offset rows
and columns from the origin (usually the upper left corner). Data
type conversion is automatic.
saveDataset:- saves a raster data object in a file using the driver of the object
saveDatasetAs:- saves a raster data object in a file using the specified driver
copyDataset:- make a copy of raster data object in a file using the specified driver
deleteDataset:- delete the file from which the raster data object was read (should only delete files opened as GDALDataset objects
