Abstract

This paper explores a new approach towards the distributed e-map service with CORBA. The architecture of a distributed e-map service model is described. This model mainly contains a distributed map database, a database connection layer, an application service layer and a client layer. For the sake of convenient transmission of map data, a combination of CORBA and GML method is introduced. Furthermore, in order to keep the loading balance among distributed servers, object migration is implemented among servers and security is considered.
