The performance of RIT's Digital Imaging and Remote Sensing Image Generation (DIRSIG) model is validated. The model is robust enough to treat solar, atmospheric, target/background, and sensor interactions. It operates over the 0.28 - 28 micrometers (Ultraviolet- Long Wavelength Infra-Red) spectral region. However, this study focuses only on the 0.4 - 1.0 micrometer (reflective) region. To validate the model, reference (actual) imagery from an airborne frame sensor is compared to synthetic imagery of the same scene. This study also evaluates DIRSIG's treatment of reflectivity and recommends improvements.
