An Urban Planning Web Viewer Based on AJAX

The Program for Promoting the Urbanism Network is a Spanish project promoted by red.es. The main goal of this project is the systematization of the urban planning of all the municipalities of the country using a single conceptual model that will end with the regional differences. The program has two main goals: first, building a Transactional Planning Management System based on a service-oriented architecture (SOA) of spatial services for processing the urban information, and second, providing an environment for publishing the information in the urban planning based on the standards for the creation of Spatial Data Infrastructures (SDIs). In a first phase, a collection of databases for the urban planning of different areas was generated, as well as a collection of services for the exploitation of the databases, and finally, different versions of viewers for the urban planning information. The services isolate the designers of urban data systems from the internal complexities of the data model, whereas the viewers allow final users to access the information in an easy and fast way. We show in this paper the Urban Planning Web Viewer for the Spanish municipality of Abegondo. The main features of the application are the modular architecture based on standard services, and the exclusive use of both AJAX (Asynchronous JavaScript and XML) and DHTML (Dynamic HTML) technologies in order to provide an extensible and very useful application with a high level of accessibility.
