GDALTransientDataset-class {rgdal} | R Documentation |
GDALTransientDataset
is identical to
GDALDataset-class
except that transient datasets are not associated with any
user-visible file. Transient datasets delete their associated file
data when closed. See saveDataset
and
saveDatasetAs
.
Objects can be created by calls of the form new("GDALTransientDataset", driver, rows, cols, bands, type, options, handle)
.
