Paper Abstract

GIS middleware is a mediator between application (or logical level) and basic services (or physical level), which is a key part of GeoInformation web services, can adapt to the context changes including spatial-temporal data, devices, situation of user, and services. There are many researches achievements of context-sensitive pervasive computing middleware existed. But in the GIS Field, it is very little about research on architecture of context-sensitive spatial information service middleware. This paper focuses on the system architecture of GIS middleware to support the building of context-sensitive applications. Four main components of GIS middleware: GIS Core Service, Context Manager, Data Adapter, and GIS Service Provider, are introduced in detail.GIS middleware is a mediator between application (or logical level) and basic services (or physical level), which is a key part of GeoInformation web services, can adapt to the context changes including spatial-temporal data, devices, situation of user, and services.
