基于Java Applet的WebGIS的瓶颈问题研究

Research on the Bottleneck Problem of WebGIS Based on Java Applet

WebGIS是将Internet技术应用于GIS开发的产物,是GIS发展的趋势之一。首先,比较了几种主要的WebGIS技术,并对基于Java技术的WebGIS系统开发方式作了总结。然后,结合具体系统实例,介绍了系统的框架,阐述了基于Java Applet的实现机制。最后着重探讨了瓶颈问题的解决措施。

It leads to the birth of WebGIS to combine Internet with GIS,which is one of the GIS development trends in the future.Firstly,it carries through the comparison among several primary WebGIS technologies and summarizes the WebGIS development manners based on the Java technology.Then,introduced the framework with specific system,and it expounds the mechanism of the WebGIS based on Java Applet.Finally,Focused on the measures to solve the bottleneck problem.
