The transition from DIRSIG 3 to DIRSIG 4 was a major shift towards a more modern code architecture and a more flexible simulation design. The goal was to address the development challenges faced at that time and to be ready for the new features and capabilities that would come. During the past few years, we have added new modalities (particularly LiDAR), new platform support (Windows), an entirely new GUI interface, native 3D radiative transfer code, extensive sensor and platform modeling, support for more complex scene radiometry, and many other features to support user needs. Every new piece of code has expanded, and in some cases, stressed, the underlying DIRSIG 4 framework and its original design. While this evolution has been successful functionally, we have made sacrifices to execution speed and our agility adapting to new challenges and projects well beyond the scope of what was imagined, or even possible, when that framework was constructed. DIRSIG 5 (D5) represents another maj...
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.
