Summary: It is widely known that modeling and design are key activities in developing information systems. A good design model helps to achieve modularity and ease of evolution and maintenance. Unfortunately these aspects have often been neglected in the area of geographic information systems (GIS), as performance and accuracy issues have been favored instead of more conceptual ones. In this paper a survey of existing approaches for modeling and designing GIS applications is presented. The nature of design activities in GIS applications is first discussed; some notations and methods related with GIS design are then analyzed; finally an object-oriented approach, based on design patterns and integrating discrete and continuous data into an uniform design model is shown.
