DESCRIPTION
WARNING: This module is superseded and will be removed in future versions of GRASS. Use the much faster
r.out.gdal instead. r.out.gdal.sh 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 ’gdal_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.
For possible metaopt parameters see the 'supported formats' pages of GDAL. The createopt may be used to
create TFW or World files ("TFW=YES", "WORLDFILE=ON").
SUPPORTED FORMATS
The set of supported formats written by r.out.gdal.sh depend on the local GDAL installation. Available
may be (incomplete list):
AAIGrid: Arc/Info ASCII Grid
BMP: MS Windows Device Independent Bitmap
BSB: Maptech BSB Nautical Charts
DTED: DTED Elevation Raster
ELAS: ELAS
ENVI: ENVI .hdr Labelled
FIT: FIT Image
GIF: Graphics Interchange Format (.gif)
GTiff: GeoTIFF
HDF4Image: HDF4 Dataset
HFA: Erdas Imagine Images (.img)
JPEG2000: JPEG-2000 part 1 (ISO/IEC 15444-1)
JPEG: JPEG JFIF
MEM: In Memory Raster
MFF2: Atlantis MFF2 (HKV) Raster
MFF: Atlantis MFF Raster
NITF: National Imagery Transmission Format
PAux: PCI .aux Labelled
PCIDSK: PCIDSK Database File
PNG: Portable Network Graphics
PNM: Portable Pixmap Format (netpbm)
VRT: Virtual Raster
XPM: X11 PixMap Format
NOTES
When writing out GeoTIFF format for users of ESRI software or ImageMagick, the band interleaving should
be switched to pixel interleaving using createopt="INTERLEAVE=PIXEL". Multiple options have to be
specified as comma separated list (createopt=TFW=YES,COMPRESS=DEFLATE).
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 type as well.
Moreover, some GDAL-supported formats do not support all the data types possible in GDAL and GRASS. Use
r.info 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 Typical boundaries of primitive
integral types for details.
EXAMPLE
Export of the map 'elevation.dem' from the Spearfish data set:
r.out.gdal.sh elevation.dem format=GTiff type=Int16 output=elev_dem.tif
