Extensis (Formerly LizardTech) MrSID Reader

Licensing options for this format begin with FME Desktop Professional Edition.

The MrSID reader allows FME to read data in the MrSID format1.

With the MrSID format, large raster image files such as aerial photographs or satellite imagery are compressed and can be quickly viewed without having to decompress the entire file.

Reader Overview

FME considers a single MrSID file to be a dataset.

MrSID files contain pixel data and each pixel in the file is a point in a single FME raster feature.

FME Raster Features

FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. The topics below describe how FME processes raster data.
