The u-GIS spatial information technology requires the processing of Geosensor information. Geosensor information processing generates real-time and high-volume location and data streams related to locations. To process this kind of data, Data Stream Management Systems (DSMS) and Spatio-Temporal Data Stream Management System (ST-DSMS) are being researched. However DSMS deals with general data streams that do not consider spatial and temporal domains. ST-DSMS supports the processing of spatial and temporal domains. However, ST-DSMS is based on continuous query processing over sliding windows the queries in ST-DSMS that are limited to expressing various spatio-temporal predicates.
