Move results of an EE task saved in Google Drive to a local directory.
ee_drive_to_local(task, dsn, overwrite = TRUE, consider = TRUE, quiet = FALSE)
task | List generated after finished correctly a EE task. See details. |
---|---|
dsn | Character. Output filename. If missing, a temporary file will be assigned. |
overwrite | A boolean argument which indicates indicating whether "filename" should be overwritten. By default TRUE. |
consider | Interactive. See details. |
quiet | logical. Suppress info message |
filename character vector.
The task argument needs a status as task "COMPLETED" to work, since the
parameters necessary to identify EE objects into google drive are obtained
from ee$batch$Export$*$toDrive(...)$start()$status()
.
consider
argument is necessary since Google Drive permits users to
create files with the same name. consider
uses an interactive R
session by default to help users identify just the files that they want to
download. Additionally, the options "last" and "all" are implemented. "last"
will download just the last file saved in Google Drive while with "all" all
files will be downloaded.
