Abstract : Nowadays, sensors networks linked to databases are more and more used in many geographic fields, such as environmental and industrial monitoring. The real time management of spatio-temporal data resulting from sensors seems problematic in accordance with real time structuring and storage in databases. Moreover, this management needs complementary information in order to simplify the decision making process in critical situations (network and sensor status, context and environment description of data acquisition, accuracy and reliability of data transmission, etc.). The whole of this information is added into metadata allowing end-user to be better informed about the quality of received and queried data in real time. Therefore, the goal of this paper is to present an analysis of real time spatio-temporal metadata in order to provide users with complementary information in real time, especially in critical situations.
