This paper describes an approach to reusing Synthetic Training Environment (STE) One World Terrain (OWT) content in both legacy simulators and modern real-time 3D engines using the CDB synthetic terrain standard. Having synthetic terrain standards is important because having a shared understanding of the data representing the environment is necessary in order to achieve interoperability between simulation systems. A government funded project executed by Maxar and SimBlocks has resulted in a tool to convert existing One World Terrain content in the Well-Formed Format (WFF) into CDB. The Well-Formed Format is largely based on 3D Tiles, and both 3D Tiles and CDB are terrain standards adopted by the Open Geospatial Consortium (OGC). The generated CDB terrain has been demonstrated in Unreal Engine 5. This paper will cover the benefits of the One World Terrain content, advantages and differences between 3D Tiles and CDB, lessons learned from developing the conversion tool, how the tool will be used by the government funding agency, and future recommendations.
