IDRISI Raster Reader/Writer

FME can access data in the IDRISI Raster format.

IDRISI Raster is the raster format used by Clark Lab’s TerrSet (formerly IDRISI) geographical information system. An IDRISI Raster will either store a single band (with potential for a palette) or an RGB dataset with bands interleaved in the order Blue, Green, Red.

Two files in conjunction define a conventional RST dataset: An .rst containing the raw image file, and an .rdc containing the description of the raster.

Two additional sidecars may also define the dataset if they are necessary: An .smp containing a color palette for the dataset, and a .ref containing geographical reference data for the dataset.

FME Raster Features

FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data.
