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. |
