- Options: none,packbit,deflate
- Default: none
DESCRIPTION
This program converts a GRASS raster file to a TIFF raster file. Output may
be 8 or 24 bit (TrueColor). Optionally, a TIFF World file compatible with
ESRI's and other's products may be output.
The program prompts the user for the name of a GRASS raster file, an output
TIFF file, whether an 8 or 24 bit format is desired, and whether or not to
create a TIFF world file. Currently only uncompressed, packpit, or deflate
TIFF files are written. These output formats are known to be compatible
with r.in.tiff.
When writing with "-l" option, tiles are written at 128x128 pixels. For
programs that can utilize tiles, it can help speed up some drawing
operations.
The user may adjust region and resolution before export using
g.region.
A better choice to export GRASS raster data might be
r.out.gdal.
