Abstract
The increasing popularity of the Internet has led to the development of Web applications, known as Web GIS, intended for dissemination and manipulation of spatial knowledge. In this paper we present a method for the development of Web GIS based on the WebML approach. In particular, we adapted the WebML development process to this specific domain, by defining the required steps and actors and by extending the visual formalism to capture specific GIS concepts. The resulting method consists of two orthogonal perspectives: Geodata and Metadata Conceptual Model and Hypertext and Web Mapping Model. In particular, the Spatial E-R model by Calkins has been exploited to design the conceptual schema of spatial data. While, the WebML Hypertext Model has been extended to include new notations specifically tailored for GIS concepts and tasks.
