Scalable and Interoperable Tourism Information System based on the WebGIS
5. XML-Based Virtual Map Interfaces
In TATIS, query results are returned as map and tabular data from the mediator to the user interface on a Web client based on SVG rendering capabilities of Internet Explorer 5. The results of the integration of GIS data and tourism data will be touristic maps including the information where touristic objects are, how they can be reached, and which objects are located nearby. SVG allows to interact, analyze, and use screen-related functions, such as zooming and panning. It will lead to change in maps from static raster graphics to interactive graphical representations that allow the presentation of the most extensive information possible thus satisfying the demands of the users.
6. Conclusion and Future Work
As discussed in the previous section, TATIS framework based WebGIS and XML-based technologies, for integrating distributed and heterogeneous data elements of TISs have been proposed. In contrast to exiting most conventional TISs in the world, this new design poses fundamentally new challenges: the geographic searching for tourist objects and dynamically generating scalable and interoperable tourist maps. The architecture of this system is logical integration for geographic information stored in a GIS system and tourism information stored in database management system. This approach to present integrated GIS and tourism information is based on the following concepts: a powerful geographic search which is the base to create dynamically generated vector maps in SVG which are enriched with additional tourism layers, to offer the users fast, flexible and meaningful access to the data to fulfill their requirements. The value of this study and its implications lie in providing us with an initial set of relevant technologies, requirements and issues to consider the in development of WebGIS-based TIS using XML and SVG.
We also create some API using XML and SVG programming. We will develop a prototype for implementing and testing, and this prototype will be implemented fro the tourism information system in Tel Aviv City of Israel.
