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 section.

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.
