520 _aGeographic Information Systems (GIS) are used to collect, store, analyze and present information describing physical and logical aspects of real world entities. They deal with several areas, such as georeferencing, topology, visualization, representation of continuous information and so on. Most of GIS applications are hardly adapted to new requirements, like changing of the reference system, integrating vector and raster models, or handling continuous information, among others. 2. THE ARCHITECTURE Our model was divided in four main pieces. The first is aimed to solve the georeferencing problem. The second is the Topological Model, which allows defining the relationship between geographical objects. The third deals with continuous fields, allowing to define and to operate them. Finally, we have a visualization model that let us customize geographical entities's aspects according to the context. This work presents an pattern driven architecture for building GIS applications. The result is a framework that is focused on flexibility and adaptability features.
