The standard for the Synthetic Training Environment (STE)

Cesium works with Vricon, a Maxar Company, to build the US Army’s One World Terrain (OWT) Well Formed Format on 3D Tiles for high-speed creation, processing, and dissemination of high resolution terrain.

This realistic, common, accessible and automated 3D terrain dataset is usable by all simulation trainers that represent the complexities of the Operational Environment (OE) in support of training as provisioned through the STE.
