摘要
以华中科技大学主校区的查询和漫游为例,在VisualC++6.0下使用ESRI提供的GIS控件MapObjects2.0,编制三个程序,通过MFC中的CSocket套接字实现了三个程序间的多机协作,并给出了通信控制协议.演示效果表明对于在多块大屏幕上进行监控的大型GIS应用,多机协作方式在表现与空间位置有关的数据之间的联系更加有效。
Take the query and roam of the main campus of HUST for example,three programs using GIS ActiveX control MapObjects2.0 provided by ESRI have been developed in Visual C++6.0, and the multi computer cooperation has been implemented through CSocket class of MFC among three programs. The protocol of communication and control is given in the end of this paper. The demonstration shows that the multi computer cooperation is more efficient for large GIS applications monitoring on several projection screens on representing connection among data which relate to spatial location.
