Meta Raster Format (MRF) Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
User attributes are not supported.
Because an MRF raster contains multiple pyramided levels, a single MRF will usually contain many features. Each of these features will have the following attributes.
Attribute Name |
Contents |
---|---|
mrf_type |
This will always be mrf_raster. |
mrf_compression_strategy |
JPEG, PNG, JPNG, TIFF, or NONE, indicating how the raster was compressed. |
mrf_interleave_strategy |
BIP (band interleaved by pixel) or BSQ (Band sequential interleave), indicating how the bands were interleaved. |
mrf_pyramid_level |
Indicates which level of the pyramid this raster defines. |
mrf_pyramid_level{n}_num_[columns/rows] |
Indicates the dimensions nth pyramid level. Will only be present on the base (0) pyramid level raster. |
mrf_subdataset_description |
A brief description of the subdataset. |
mrf_subdataset_name |
The internal name of the source subdataset. |
mrf_tile_columns/rows |
The dimensions of the current raster. |
mrf_z_size |
The number of z-slices. Will only be on the base (0) pyramid level raster. |
mrf_z_slice |
Identifies which z-slice this raster came from. |
