Abstract (EN)
This paper deals with issues related to the exchange and integration of geographic data between producers and users. Once a producer has delivered a geographic database to a user, who uses it as a reference for his specific applications, the database may be updated on both sides. Consequently, the integration of updates - delivered by the producer -in the user's geographic database is a complex operation due to possible conflicts between updates performed by both actors. The resulting database may be in an inconsistent state and user's added information may be lost. Therefore, users need mechanisms to help them in the process of update integration. This paper provides a methodological framework for the updating of geographic databases. It relies on a multiversion GIS, allowing an automatic detection of conflictual updates between two map versions.
