GIS applications manage information with a spatial component, usually in the form of points, lines, polygons, or variants of these basic data types, in domains where the spatial information plays a central role. They provide the user with different functionalities on different application domains, but they are usually developed according to a common architecture and using a common set of technologies. Hence, they share a significant number of elements that make some aspects of their development quite repetitive. Our DSL allows developers to specify the entities, geographic layers, and maps of the applications using a declarative language. Then, the specification is transformed into a working GIS application. We present the language, its implementation, and a case study on two sample projects that allowed us to evaluate the resulting software, paying special attention to the savings in the development effort.eng© 2020 River PublishersDomain specific languageGeographic information systemsOpen source toolsWeb applicationsjournal articleembargoed access10.13052/jwe1540-9589.1923
