RRASTER – R Raster

Driver short name


New in version 2.2.

Driver built-in by default

This driver is built-in by default

This is a read-only reader for the datasets handled by the R Raster package. Those datasets are made of a .grd file, which is a text header file, and a .gri binary file containing the raster data itself. The .grd is the file opened by GDAL. Starting with GDAL 2.3, the driver will read ratvalues as RAT or color tables. Layer names will be assigned to GDAL band description. The ‘creator’ and ‘created’ attributes of the ‘[general]’ section will be assigned to the GDAL ‘CREATOR’ and ‘CREATED’ dataset metadata items.

Starting with GDAL 2.3, the driver has write capabilities. Color tables or RAT will be written. The ‘CREATOR’ and ‘CREATED’ dataset metadata items will be written as the ‘creator’ and ‘created’ attributes of the ‘[general]’ section. Band description will be written as the ‘layername’ attribute of the ‘[description]’ section.

The following creation options are supported:

  • INTERLEAVE=BIP/BIL/BSQ. Respectively band interleaved by pixel, band interleaved by line, band sequential. Default to BIL

  • PIXELTYPE=SIGNEDBYTE. To write Byte bands as signed byte instead of unsigned byte.
