Telegeomatic system and real time spatio-temporal Database

Abstract : Telegeomatics, geomatic and telecommunications, is currently in strong growth. Many applications require tools to manage and locate information on mobile data and/or real time. The management of fleet vehicles in real time (transport, taxis...), the follow-up of the environment, management of crises (catastrophes, fires...), urban risk management (motorway, road, industrial...) or environmental risk (risings, avalanches, volcanos...) require information processing systems able to exploit spatio-temporal and real time data. These data are issued from sensors and fixed or mobile systems of localization. Current GIS manage and allow managing of spatial data. These data are spatial and temporal and moreover, real time. The real time we deal with here is the immediate real time about the second what has strong implications on the management and the exploitation of these data (structuring, storage, indexing, interrogation, visualization...). The temporal aspect of the data is still badly introduced and no real time DBMS is marketed nor a spatial-temporal and real time DBMS. However, the need is crucial in particular in terms of structuring and of querying of these data. Several questions arise: how to store this mass of data quickly without overflow? How to index these data in real time while privileging recent data rather than the old ones while allowing the requests in continuous time? How to manage mobility? Which are the specifications of architectures of collection, communication, of storage in the database? Few works exist on this field. Current researches relate to the telegeomatics one binding GIS and systems of telecommunication. Existing works focus on the management of mobile telecommunications but not on the management and the exploitation of spatio-temporal and real time data. The objective of the paper is to present the problems of databases and information system concerning spatio-temporal and real time aspects.
