Moving objects spatiotemporal reasoning model for battlefield analysis
Gunwoo Park, Seong Seung Park · International Conference on Systems · 2008
In order to predict future variations of moving objects which general attributes, locations, and regions of spatial objects are changed over time, spatiotemporal data, domain knowledge, and spatiotemporal operations are required to process together with temporal and spatial attributes of data. However, conventional researches on temporal and spatial reasoning cannot be applied directly to the inference using moving objects, because they were studied separately on temporal or spatial attribute of data. Therefore, in this paper, we not only define spatial objects in time domain but also propose a new type of moving objects spatiotemporal reasoning model that has the capability of operation and inference for moving objects. The proposed model is made up of spatiotemporal database, GIS tool, and inference engine for application of spatiotemporal reasoning using moving objects and they execute operations and inferences for moving objects. Finally, to show the applicability of the proposed model, proper domain is established for battlefield analysis system supporting commander's decision making in the army operational situation and it is experimented with this domain.
