Use Convert Interleave to convert between common data storage conventions. Often, it is more efficient to use image data stored in a specific manner for specific processing operations or interactive analysis.

You can also write a script to convert the interleave of a raster using the ConvertInterleave task.

  1. From the Toolbox, select Raster Management > Convert Interleave.
  2. Click the Browse button next to Input Rasters and select an image whose interleave you want to convert.
  3. Chose an option from the Interleave drop-down list. The choices are:
    • (Undefined)
    • BSQ: Band sequential
    • BIL: Band-interleaved-by-line
    • BIP: Band-interleaved-by-pixel
  4. Select a filename and location for the Output Raster.

  5. Enable the Display result check box to display the output in the view when processing is complete. Otherwise, if the check box is disabled, the result can be loaded from the Data Manager.

  6. To reuse these task settings in future ENVI sessions, save them to a file. Click the down arrow and select Save Parameter Values, then specify the location and filename to save to. Note that some parameter types, such as rasters, vectors, and ROIs, will not be saved with the file. To apply the saved task settings, click the down arrow and select Restore Parameter Values, then select the file where you previously stored your settings.

  7. To run the process in the background, click the down arrow and select Run Task in the Background. If an ENVI Server has been set up on the network, the Run Task on remote ENVI Server name is also available. The ENVI Server Job Console will show the progress of the job and will provide a link to display the result when processing is complete. See ENVI Servers for more information.

  8. Click OK.
