Abstract
We have formulated a layered model of the environmental database which may be applied to the storage, management, interpolation, and retrieval of geo-acoustic parameters. The lowest level involves a discrete representation of measured and inferential environment data which may be obtained from a variety of sources. The highest level involves a continuous representation of environment data which is required to support propagation modelling codes. The transition from discrete to continuous domairs is facilitated by an interpolation layer. A commercial database management system is recommended to implement much of the database functionality at the lower level. This functionality, however must augmented by a spatial indexing scheme.
