RPB file is created. The default value is Configuration options This paragraph lists the configuration options that can be set to alter the default behaviour of the GTiff driver.

The Create method also supports creating streamable compatible files, but the writer must be careful to set the projection, geotransform or metadata before writing image blocks so that the IFD is written at the beginning of the file. The default is 6.

See Internal nodata masks section. The first “extrasample” is marked as being alpha if there are any extra samples.

The specification defines a set of TIFF tags to describe all geographic information associated with TIFF imagery that originates from satellite imagery systems, scanned aerial photography, scanned maps, digital elevation models, or as a result of geographic analyses.

GTiff — GeoTIFF File Format

GeoTIFF is commonly used for satellite imagery, scanned aerial photography, scanned maps, digital elevation models, or as a result of geographic analyses. First mentioned sources are the most prioritary over the next ones. Note that this creation option will have no effect if general options i.
