JPL will formulate, design, and implement an architecture to search, locate, store, retrieve and maintain a semantic-based digital library for the environmental and terrain models for mobility context. The library will be based on an expansion of the SWEET ontology. When completed, this task will provide a detailed ontology for the diverse and large set of terrains and environments for the DoD mobility context.

JPL will also develop high-fidelity, first-principles models of deformable terrains and particulate matter such as sand, clay and snow to provide detailed insight and statistical information associated with the mechanics of their interactions with mobility systems. These models are based on detailed modeling of millions of particulates using massively parallel computing systems. When completed, this task will provide models of mobility on particulate material at an unprecedented level of fidelity as well as quantitative understanding of sensitivity of mobility as a function of uncertainties in the terrain properties.

For this research, JPL is team member of the larger effort led by BAE Systems, Land & Armaments in Minneapolis.
