The Digital Imaging and Remote Sensing Image Generation (DIRSIG) model is a first principles based synthetic image generation model developed by the Digital Imaging and Remote Sensing Laboratory at Rochester Institute of Technology. The model can produce passive single-band, multi-spectral or hyper-spectral imagery from the visible through the thermal infrared region of the electromagnetic spectrum. The model also has an very mature active laser (LIDAR) capability and an evolving active RF (RADAR) capability. The model can be used to test image system designs, to create test imagery for evaluating image exploitation algorithms and for creating data for training image analysts.
