Rapid GIS Development: a model-based approach focused on interoperability

We present a framework for rapid development of GIS web applications tightly integrated with web database applications, with several innovations: a georeference abstraction, simplifying use of complex geographical geometries; use of SQL column data types to specify the user interface without scripting; interface and symbology personalization, persisting in user preferences; and a flexible implementation based on open source components, including full auditing. The framework is already used in a mission critical application.
