What other software do I need to use DIRSIG?

By Scott D. Brown - Posted on 05 September 2008

DIRSIG leverages the U.S. Air Force's atmospheric radiation code "MODTRAN". Although there are ways to run the model using empirically based atmospheric contributions, this is strongly advised against for use in rigorous studies. The MODTRAN software is currently available from www.modtran.org.

The output image data created by the model is easily read into the ENVI image processing and analysis package. However, the most common output data is a simple, double precision floating-point, band interleaved by pixel format that can be easily read into most packages.
