Use this as a template for writing your own script, changing the arguments as needed. Here is a copy of the example_spectral_index.bat script. Where idl_install_dir and envi_install_dir are the IDL and ENVI installation paths on your system.

An NDVI image will be created in the sandbox directory.

Run the script from the directory that has write permission. Run the script with the required arguments, as follows.Create a scratch directory with write permission, where temporary output can be written.This example creates a Normalized Difference Vegetation Index (NDVI) image from an input QuickBird image, by invoking envitaskengine through a Windows batch script.
