Typical File Extensions

.bil, .bip, .bsq, .*

This module provides FME with access to ENVI .hdr header files and the associated raw raster files.

ENVI .hdr is a header file that stores the georeferencing information of an associated raw raster file. The georeferencing information is stored in the .hdr file with the keywords listed in the table below.

For each raster, there is only a single feature returned, since this feature will contain the entire raster.

Reader Overview

FME considers a single file to be a dataset.

Writer Overview

The ENVI .hdr writer creates and writes data into a single folder. It distinguishes duplicate output files by appending numbers to the filenames.

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.

About FME Rasters Tiling and Mosaicking
Raster Properties Band Combining and Separating
Band Properties Band and Palette Selection
Palette Properties Raster Processing
Compression Raster versus Vector Features
Pyramiding Raster File Naming
Interleaving World Files
Interpretation and Data Type TAB Files
Palette Resolution  

ENVIHDR files can only be written with square pixel dimensions.

ENVIHDR supports rasters with an arbitrary number of bands, provided all bands are the same data type and no band has a palette.
