Using UML for Real Time Geomatic Modelisation

Facing the increase of applications around spatial or spatio-temporal databases, the assistance brought to the designer of these bases remains very poor. As in the classic data base domain (no spatial) the use of conceptual models, methods and tools of design is very current, in the real time geoprocessing application domain it is the exception. Yet, these databases are very often complex and would require a phase of detailed design. The subject of this article is to present the disadvantages of different existing methods and to propose a profile UML dressing real time constraints in the field of real time geoprocessing applications. The GRT (Geographic Real Time) profile target the design of real-time geomatic applications.
