Method and systems, for executing an interactive computer simulation of a simulated vehicle, comprising a remote data management system, a central repository, a remote repository and an interactive computer simulation station. The central repository comprises a synthetic natural environment database (SNEDB) that comprises data of a plurality of data types for geographically-located terrain skin representations. The remote data management system maintains the remote repository storing a subset of the SNEDB. The station comprises data consumers each requiring one or more data types and sends, over the network, a data request for geographical locations from the SNEDB. The station allows users to interact in the simulation for controlling the simulated vehicle. The remote data management system determines a set of data types considering requesting data consumers and updates the subset of the SNEDB for the geographical locations with data of only the set of data types.
