Feature Representation

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this topic.

MrSID features specify a matrix of x, y, and z coordinates. For each raster, there will only be a single feature returned.

Attribute Name	Contents
mrsid_type	This will always be mrsid_raster.
mrsid_image__dynamic_range_window	This represents a custom contrast setting. This is a reader attribute.
mrsid_image__dynamic_range_level	This represents the custom brightness setting. This is a reader attribute.
mrsid_image__input_file_size	This represents the size of the input image or mosaic in bytes. This is a reader attribute.
mrsid_image__input_format	This represents the name of the input image type. This is a reader attribute.
mrsid_image__input_lut	This represents a color lookup table stored as an array of 256*3 values, one value for each band (R,G,B) for each of the 256 entries in the table. This is a reader attribute.
mrsid_image__input_name	This represents the filename of the input image. This is a reader attribute.
mrsid_image__compression_ block_size	This represents the block size used in MRSID encoding. This is a reader attribute.
mrsid_image__compression_ gamma	This represents the g-weight value used in MRSID encoding. This is a reader attribute.
mrsid_image__compression_ version	This represents the version of encoder used. This is a reader attribute.
mrsid_image__compression_ weight	This represents the weight value used in MRSID encoding. This is a reader attribute.
mrsid_image__creation_date	This represents the date and time of image encoding. This is a reader attribute.
mrsid_image__compression_ nlev	This represents the number of zoom (resolution) levels in the image. This is a reader attribute.
mrsid_image__statistics_ max	This represents the maximum sample values for each band in the input image. The number and data type of the values correspond to the number of bands and sample type of the image. This is a reader attribute.
mrsid_image__statistics_ min	This represents the minimum sample values for each band in the input image. The number and data type of the values correspond to the number of bands and sample type of the image. This is a reader attribute.
mrsid_image__statistics_ mean	This represents the average value of all samples for each band. This is a reader attribute.
mrsid_image__statistics_ standard_deviation	This represents the standard deviation of all samples for each band. This is a reader attribute.
mrsid_image__target_ compression_ratio	This represents the compression ratio used for encoding. This is a reader attribute.
mrsid_image__z_origin	This represents the z-coordinate of the origin. Cell values in the raster are relative to this origin. This is a reader attribute.
mrsid_image__z_resolution	This represents the georeferencing pixel resolution in the z-direction. This is a reader attribute.
mrsid_image__no_dither	The presence of this attribute indicates the image is not dithered. This is a reader attribute.
mrsid_version	The version of the MRSID file. This is a reader attribute.
