With ever increasing challenges in spatially-related managing and decision making applications, wired GIS cannot meet the demands of users for easy access to spatial data and spatial analysis. Wireless spatial data service is one of the fastest growing areas in the information technology. Most of mobile users tend to access location information via wireless network. Many efforts have been made to reach this goal, and lots of technologies have been introduced in wireless world for serving spatial information. This paper discusses the process of constructing a wireless GIS, using Java and XML technologies. Using some spatial data layers in XML format and applying in a Java program, an interface with a search module to select requested region has been developed, which uses Java code, and XML parsers to act on XML and results are displayed using java graphical procedures. Integrating these two nouvelle technologies makes better results in performance and transaction speed, in comparison with conventional systems. |
