.SH DESCRIPTION
WARNING: \fBThis module is superseded and will be removed in future versions of GRASS.
Use the much faster \fIr.out.gdal\fR instead.\fR
\fIr.out.gdal.sh\fR outputs GRASS raster maps into various GIS formats
as supported by GDAL. This script is based on 'gdal_translate',
it's parameters are similar to those of 
\(cqgdal_translate'.
It requires the installation of either GDAL with GRASS support or
of the GDAL-OGR-GRASS plugin which is available from the 
GDAL web site.
.PP
For possible \fImetaopt\fR parameters see the 'supported formats' pages
of GDAL.
The \fIcreateopt\fR may be used to create TFW or World files ("TFW=YES",
\(dqWORLDFILE=ON").
.SH SUPPORTED FORMATS
The set of supported
formats written by \fIr.out.gdal.sh\fR depend on the
local GDAL installation. Available may be (incomplete list):

.SH NOTES
When writing out GeoTIFF format for users of ESRI software or ImageMagick,
the band interleaving should be switched to pixel interleaving using
\fIcreateopt="INTERLEAVE=PIXEL"\fR. Multiple options have to be
specified as comma separated list (\fIcreateopt=TFW=YES,COMPRESS=DEFLATE\fR).
.PP
Out of the GDAL data types, the closest match for GRASS CELL, FCELL and DCELL
rasters are respectively Int32, Float32 and Float64. These are not exact
equivalents, but they will preserve the max possible data range and number of
decimal places for each respective GRASS raster data type. Please keep in mind, that
not all CELL rasters will require Int32 - e.g., 0-255 CELL raster are covered
by the Byte \fItype\fR as well. Moreover, some GDAL-supported formats do not
support all the data types possible in GDAL and GRASS. Use
\fIr.info\fR to check the data type and range for your
GRASS raster, refer to specific format documentation
(GDAL website, format vendor's docs) and
e.g. the Wikipedia article
\fITypical boundaries of primitive integral types\fR
for details.
