http://www.discerningtruth.org/ WebNov 2, 2024 · DIRSIG is a first-principle radiative transfer image and data simulation tool. It generates airborne and satellite imagery through unified path-tracing approaches for light transport. This process generates sensor-reaching radiance from geometric objects and the Earth’s surface, attributed with reflectivity and emissivity models.
