renameDataset() renames a dataset in a format-specific way (e.g., rename associated files as appropriate). This could include moving the dataset to a new directory or even a new filesystem. The dataset should not be open in any existing GDALRaster objects when renameDataset() is called. Wrapper for GDALRenameDataset() in the GDAL API.

Usage

renameDataset(new_filename, old_filename, format = "")

Arguments

new_filename

New name for the dataset.

old_filename

Old name for the dataset (should not be open in a GDALRaster object).

format

Raster format short name (e.g., "GTiff"). If set to empty string "" (the default), will attempt to guess the raster format from old_filename.

Value

Logical TRUE if no error or FALSE on failure.

Note

If format is set to an empty string "" (the default) then the function will try to identify the driver from old_filename. This is done internally in GDAL by invoking the Identify method of each registered GDALDriver in turn. The first driver that successful identifies the file name will be returned. An error is raised if a format cannot be determined from the passed file name.

Examples

b5_file <- system.file("extdata/sr_b5_20200829.tif", package="gdalraster")
b5_tmp <- file.path(tempdir(), "b5_tmp.tif")
file.copy(b5_file,  b5_tmp)
#> [1] TRUE

ds <- new(GDALRaster, b5_tmp)
ds$buildOverviews("BILINEAR", levels = c(2, 4, 8), bands = c(1))
#> 0...10...20...30...40...50...60...70...80...90...100 - done.
ds$getFileList()
#> [1] "/tmp/Rtmpi7gt4V/b5_tmp.tif"     "/tmp/Rtmpi7gt4V/b5_tmp.tif.ovr"
ds$close()
b5_tmp2 <- file.path(tempdir(), "b5_tmp_renamed.tif")
renameDataset(b5_tmp2, b5_tmp)
#> [1] TRUE
ds <- new(GDALRaster, b5_tmp2)
ds$getFileList()
#> [1] "/tmp/Rtmpi7gt4V/b5_tmp_renamed.tif"    
#> [2] "/tmp/Rtmpi7gt4V/b5_tmp_renamed.tif.ovr"
ds$close()

deleteDataset(b5_tmp2)
#> [1] TRUE
