Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (seeAbout Feature Type Attributes), this format adds the format-specific attributes described in this topic.
ERDASRAW features specify a matrix of x, y, and z coordinates. For each raster, there will only be a single feature returned.
Attribute Name |
Contents |
erdasraw_type |
This will always beerdasraw_raster. |
erdasraw_layer_type |
This indicates whether the image is thematic or athematic. The valid values for this attribute are THEMATIC and ATHEMATIC. |
erdasraw_binary_extension |
This represents the extension to be used for the binary raster file that is written along with the ERDAS .raw header. The default is no file extension, there is also a feature type default parameter which may be set. |
erdasraw_padding_value |
This represents the byte value of each byte in the header being written out. It must be an integer between 0 and 255 inclusive. The default is zero, there is also a feature type default parameter which may be set. |
erdasraw_header_size |
This represents the number of bytes of the header in the file before where the actual raster data locates. It must be an integer and non-negative. The default is zero, there is also a feature type default parameter which may be set. |
erdasraw_interleaving_type |
Sets the interleaving of the output file. Valid values areBILandBSQ. The default isBSQ. This is a writer attribute. |
erdasraw_byte_order |
Sets the byte order of the output file. Valid values areMSB,LSB, andmachine(meaning the native byte order of the machine running FME). The default ismachine. This is a writer attribute. |
