Designing adaptable geographic objects for mobile applications

In this position paper we discuss the evolution of an object-oriented framework for GIS applications into a platform for dealing with mobile users and geographic objects. We first motivate our research by discussing the state of the art of mobile GIS applications, the so-called location-based services using a simple scenario. We briefly describe an object-oriented architecture for dealing with discrete and continuous geographic data and show how good design practices allowed us to make geographic objects adaptive to mobile users. Some concluding remarks are finally presented.
