A Novel Model Driven Framework for the Development of Web-based Graphical Information Systems

Abstract

Web-based Geographic Information Systems (Web-based GIS) are crucial for organizations that provide Internet-based locational services to their users, however, the development of Web-based GIS requires expensive professional expertise, making it challenging for resource-constrained organizations to develop their own Web-based GIS from scratch. While Google Maps can automate any simple Web mapping scenario, it does not allow for custom feature development. To add custom features, Google Maps API is used, but high-level implementation raises the overall development costs, making it expensive for budget-limited companies due to the increase in developers’ costs and development time. To overcome these challenges, we propose a GeoLocation System (GLS) framework with a model-driven approach that will allow the automatic development of a Web-based GIS with customized features developed using the built-in functions of Google Maps API. The framework provides a meta-model that incorporates essential concepts for Web-based GIS development. We have also proposed two novel features using OCL constraints to enhance the framework's capabilities. Furthermore, our framework includes a customized Tree Editor, Graphical Modeling Tool, and Transformation Engine that is capable of automatically transforming the models created by the tool into executable Web-based GIS code. The source code generated through the framework can be directly opened on any Web browser without any need for manual modification. The proposed framework is validated using a realworld case study which demonstrates its effectiveness in reducing the overall development complexity, developers’ cost, and overall development time.
