Abstract
Recent advances in web technologies, such as those used by Google Maps, have facilitated the development of more interactive geospatial mapping technologies. The technology behind these mapping tools is known as Asynchronous JavaScript and XML (AJAX), which is aimed at more stable functionality, fast interactivity between servers and clients, and cost-effective data exchanges between the servers behind the scenes. Although Google Maps takes full advantage of this recent technology, there are still many restrictions in terms of customization, source modification, and licensing issues. We propose to use ka-Map, which is a very powerful tool for customizing user components such as graphical user interfaces (GUI). Ka-Map can be coupled with MapServer, which was developed at the University of Minnesota. Since both ka-Map and MapServer are open source web-mapping technologies that are compliant with Open Geospatial Consortium (OGC) standards, application of these tools for water resources management is of great interest.
