Intergraph Raster Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The Intergraph Raster Reader/Writer allows FME to access data in the INGR format.

Overview

INGR is a file format used by Intergraph to store raster data. It supports several different data formats for reading and writing, each of which is specialized for the performance of the Intergraph software.

Reader Overview

FME considers a single INGR file to be a dataset. Each dataset contains a single FME raster feature.

Writer Overview

FME considers a dataset to be a folder name.

The name of the INGR output file written to the output dataset folder is determined by the interpretation type of the raster.

If the raster contains color bands, it will be written to an .rgb file.
If the raster contains a band with a palette, it will be written to a .cot file.
If the raster is numeric, it will be written to a .grd file.

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.
