Data representation for sensor models within a synthetic natural environment (SEDRIS)

The Synthetic Environment Data Representation and interchange Specification (SEDRIS) methodology enables representation and interchange of environment al data between heterogeneous simulation systems. Central to the SEDRIS met hodology is the correlation of local Synthetic Environment data models with the generalized SEDRIS Data Representation Model prior to the interoperati on of a distributed system. The Unified Modeling Language and associated Da ta Dictionary provide the means to umambiguously articulate information abo ut the Data Representation Model. We consider the general representation of sensor systems in the SEDRIS Data Representation Model, provide a survey o f sensor simulations, and discuss enhancements to SEDRIS Data Representatio n Model stemming from our investigation. Future extensions to this methodol ogy are also suggested.
