Advances in Spatiotemporal Interoperability based on HLA and OGC Standards

The Distributed Spatiotemporal Interoperability (DALI) approach addresses the issue of Interoperability between the separate domains of geoinformation (GI) and modeling & simulation (M&S) technology. While interoperability is often limited to a specific domain, DALI tries to exploit the synergies of coupling OGC-compliant services and HLA-based simulations in a standardized manner. The paper describes the status of the evolving DALI concept in its current third development stage and takes a closer look at the latest advances in addressing open questions of cross-domain interoperability based on the OGC and HLA specifications. 1
