Dynamic Interoperable Geoprocessing and Geosimulation An OpenGIS/HLA based Interoperability Architecture

The HLA addresses interoperability issues in the distributed simulation domain successfully. Similar approaches are noticeable in the geo-processing domain. The future of geo-processing applications will be based on the interoperability of geographic data and geographic services that are distributed over heterogeneous networks. In view of the inherent space-time nature of most of the dynamic models that are developed for analysis, training, forecasting, and other purposes, the integration of both the temporal and the spatial dimension would be highly beneficial. Based on the discussion of the potential as well as the current shortcomings of the two initiatives to support distributed spatio-temporal processing and integrating web based architecture will be presented and demonstrated by an emergency management system example. This approach includes a generic customization of the given standards as well as the specification of web-based integration services to make geo-services available to HLA federations and vice versa. The long term goal of this approach is making standardized off-the-shelf GIand simulation services usable for highly specialized simulation and controlling applications.
