The Export BIL/BIP/BSQ/ERS/RAW command allows the user to export any loaded raster, vector, and/or elevation grid data to a BIL, BIP, BSQ, ERS (ERMapper Grid), or RAW format file. Note that ERS and RAW files are the same as BIL, which is just a flat binary file with one or more header files describing the file layout.
When selected, the command displays the BIL/BIP/BSQ Export Options dialog which allows the user to setup the export. The dialog consists of an Options panel (pictured below), which allows the user to set up type of export to perform, the sample spacing, vertical units, and other applicable options, a Tiling Panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
