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 stores a synthetic natural environment database (SNEDB) that comprises data records for a plurality of geographically-located terrain skin representations of a computer generated environment. The remote data management system maintains the remote repository storing a subset of data records from the SNEDB. Each one of the subset of data records has a priority tag. The station sends a data request for geographical locations from the SNEDB and allows users to interact in the simulation for controlling the simulated vehicle. The remote data management system monitors remaining storage capacity of the remote repository and, upon reaching a high-level threshold value, removes the most extraneous data record considering priority tags until reaching a low-level threshold value.
