Modeling and Simulation

The DIRS Modeling and Simulation group is primarily responsible for development of our remote sensing simulation capabilities. These tools are used in the precise radiometric representation of remote sensing scenes over a wide spectral regime. They not only develop simulation capabilities for DIRS, but they also maintain expertise in external modeling codes such as atmospheric and in-water radiative transfer simulation tools.

The primary RIT-developed tool is DIRSIG, the Digital Imaging and Remote Sensing Image Generation simulation package. It is a leading package for remote sensing scene and image chain analysis simulations. Common uses include sensor / system performance evaluation, algorithm training and evaluation, and analyst hypothesis testing. Additionally, RIT continues to develop the Forecasting and Analysis of Spectral Sensor Performance, or FASSP, model. This simulation does not model a specific scene, but allows for rapid sensor parametric analysis for specific tasks of interest.
