Spatio-temporal processing of geoinformation for decision making in critical situations

摘要

The effective spatio-temporal processing of geoinformation is crucial in the area of civil protection. The article covers essential aspects including security side related to the deployment of a complex spatial data infrastructure for decision making in critical situations. Nine civil protection and risk management pilots have been deeply analysed in order to find and solve common issues for accessing and processing the available spatial datasets. The key emphasis was placed on temporal aspect of the spatial data, as the time dimension is crucial in civil protection applications. The consideration of time dimension, as the key aspect for the management of particular emergency situations (i.e. earthquakes) has brought to the novel use of the granularity and the update frequency in the set of metadata elements. The final software architecture uses a modular methodology based on a federated approach to data collection, processing and distribution of spatio-temporal data.
