R: Class "GDALDataset"

GDALDataset-class {rgdal}

R Documentation

Class "GDALDataset"

Description

GDALDataset extends GDALReadOnlyDataset-class with data update commands.

Usage

putRasterData(dataset, rasterData, band = 1, offset = c(0, 0))
saveDataset(dataset, filename)
copyDataset(dataset, driver, strict = FALSE, options = '')
deleteDataset(dataset)
saveDatasetAs(dataset, filename, driver = 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
`driver`	GDAL driver name to use for saving raster data object
`strict`	Driver specific options (currently passed to GDAL)
`options`	Driver specific options (currently ignored)

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

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. Class "GDALMajorObject", by class "GDALReadOnlyDataset".
