An Esri .hdr file is a header file that stores the georeferencing information of an associated raw raster file. The georeferencing information is read from or written to an Esri world file but is also 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.

Notice that the current version of Esri .hdr Raster reader/writer does not support the bandrowbytes, totalrowbytes, and bandgapbytes keywords. This format also supports an optional colormap ASCII file that allows for an RGB palette to be stored in a separate .clr file if present.

The raw data file for Esri .hdr datasets can have multiple extensions depending on the interleaving type of the file. The extension becomes one of the following allowable interleaving options: BIP, BSQ, BIL. Thus an Esri dataset with a band order by pixel interleaving would have a .hdr file and a .bip file.

Esri world files will be read if present and written alongside Esri .hdr datasets. World file extensions also match the interleaving type of the dataset.

  • BIP – .bpw
  • BSQ – .bqw
  • BIL – .blw

Reader Overview

FME considers a single file to be a dataset.

Writer Overview

The Esri .hdr writer creates and writes data into a single folder specified in the Destination parameter in the Workbench Navigator.

The Esri .hdr writer 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.

For comprehensive information about how FME processes raster data, see Rasters.

Esri .hdr supports rasters with an arbitrary number of bands, provided all bands are the same data type and no band has a palette. Esri .hdr also supports rasters with a single band that has a palette.
