RMF – Raster Matrix Format
Driver short name
RMF
Driver built-in by default
This driver is built-in by default
RMF is a simple tiled raster format used in the GIS “Integration” and “Panorama” GIS. The format itself has very poor capabilities.
There are two flavors of RMF called MTW and RSW. MTW supports 16-bit integer and 32/64-bit floating point data in a single channel and aimed to store DEM data. RSW is a general purpose raster. It supports single channel colormapped or three channel RGB images. Only 8-bit data can be stored in RSW. Simple georeferencing can be provided for both image types.

Metadata
ELEVATION_MINIMUM: Minimum elevation value (MTW only).
ELEVATION_MAXIMUM: Maximum elevation value (MTW only).
ELEVATION_UNITS: Name of the units for raster values (MTW only). Can be “m” (meters), “cm” (centimeters), “dm” (decimeters), “mm” (millimeters).
ELEVATION_TYPE: Could be either 0 (absolute elevation) or 1 (total elevation). MTW only.
Open Options
- RMF_SET_VERTCS: set to ON, the layers spatial reference
will include vertical coordinate system description if exist. This feature can be enabled via config option with same name.
Creation Options
MTW=ON: Force the generation of MTW matrix (RSW will be created by default).
BLOCKXSIZE=n: Sets tile width, defaults to 256.
BLOCKYSIZE=n: Set tile height. Tile height defaults to 256.
RMFHUGE=NO/YES/IF_SAFER: Creation of huge RMF file (Supported by GIS Panorama since v11). Defaults to NO.
COMPRESS=NONE/LZW/JPEG/RMF_DEM: (From GDAL 2.4) Compression type. Defaults to NONE. Note: JPEG compression supported only with RGB (3-band) Byte datasets. RMF_DEM compression supported only with Int32 one channel MTW datasets.
JPEG_QUALITY: (From GDAL 2.4) JPEG quality 1-100. Defaults to 75.
NUM_THREADS=number_of_threads/ALL_CPUS: (From GDAL 2.4) Enable multi-threaded compression by specifying the number of worker threads. Default is compression in the main thread.
