摘要
探索基于自定义协议开发网络地理信息系统的方法。自定义一套工作于TCP/IP应用层的协议,基于该协议利用Winsock网络编程实现网络通信,基于组件GIS开发实现空间数据操作,并在通信接口中加入了自定义的通信可靠性和安全保障机制,实现了一个3层C/S结构的网络地理信息系统,验证了这种开发方式的可行性。
This paper proposes and implements a methodology for developing WebGIS. Key elements of the methodology include establishment of the self-defined protocol working on application layer of TCP/IP model, implementing communication between client and server based on the self-defined protocol by utlizing Winsock programming and realizing spatial data access interface based on COMGIS development. Based on these technologies, a WebGIS with C/S structure is implemented, andthe feasibility of the methodology is validated.
