export
Export the BooleanField to files in geoTIFF format. This enables a BooleanField to be saved, persisted, and shared.
Regardless of the original data format:
A BooleanField is always exported as 2-bit unsigned integer data
A value of 2 is used to represent NoData in the exported files
Small spatial fields are saved as a single file named outputDirectory/filenamesPrefix.tiff. Large spatial fields will be saved as multiple files using the following naming convention: outputDirectory/filenamesPrefix_0.tiff, outputDirectory/filenamesPrefix_1.tiff, ..., outputDirectory/filenamesPrefix_N.tiff. Whether a field is saved as multiple files depends on the amount of information contained by the field and the memory resources available on the host device. The .tiff extension is automatically appended to each file name.
The output directory is expected to exist and have appropriate write permissions. There should be no existing files at the export location.
To read a BooleanField from files created by this method, use BooleanField.createFromFiles with the paths returned from this method and a band identifier of 0.
An error is returned if file export is unsuccessful.
Return
A Result containing the paths of saved geoTIFF files, or an error if file export is unsuccessful.
