National Geospatial - Intelligence Agency Terrain

National Geospatial-Intelligence Agency Terrian are creating games and visual simulations to load geospatial datasets such as elevation girds, satellite imagery, and road maps. Using advanced techniques NGIATP is enhancing the datasets with procedurally generated detail. This creates more compelling and immersive environments.

NGIATP uses the SOARX terrain algorithm, which combines dynamic level-of-detail rendering with automatic high-frequency detail generation. The paging system loads 1 degree by 1 degree DTED cells as SOARX blocks complete with skirts to hide seams between blocks and coloring based on elevation. The Rendering code uses OpenGL Shading Language for efficiency and compatibility.
