The next release of DIRSIG will feature two major internal optimizations. One which will significantly speed thermal runs. The other which will speed unpolarized radiometric calculations--especially noticeable in hyperspectral cases. New functionality includes a user-configurable interactive mode, which allows for a user-specified ray/solid angle to be traced and for arbitrary data to be extracted from the solution. The output can be either easily-parsable XML or human-friendly plaintext.
A blog about the Digital Imaging and Remote Sensing Image Generation (DIRSIG) model featuring posts contributed by the developers. This is not a user manual and it is not a training class. But, it is a place to see what the developers are doing and a little about how we do it. So think of this as a place to learn cool tips, tricks, etc.
