Accessing Spatial Data Based on Java
基于Java的空间数据访问

As information descric the characteristics of spatial entities, spatial data is regarded as the most important part in the whole geographic information system. It is very significant to research the accessing methods of spatial data. In this paper, the authors discussed some problems of implementing Java-Based WebGIS. First, the authors investigate of the storage format of spatial data,then discussed the process of how to utilize the network advantages of Java language to implement the access of spatial data through Internet, and how to set up Java Applet to display the map, and finally developed a simple WebGIS using Java.
