Multi-resolution terrain depiction on an embedded 2D/3D synthetic vision system

The multi-resolution terrain concept is integrated into a hi-level certifiable 2D/3D scene graph rendering system. It runs on an aviation certifiable embedded rendering graphics board. The optimized combination of multi-resolution terrain data, scene graph organization, and graphics board allows it to handle dynamically terrain models up to 3 arc second post spacing. The system and data processing acknowledges standard certification rules for terrain database requirements, aeronautical data processing and software development (DO-178B, DO-254, DO-200A, and DO-276).
